Tatapania gen. nov., a possible cone of Schizoneura gondwanensis Feistmantelfrom the Late Permian in the Tatapani-Ramkola Coalfield, India. The Palaeobotanist 60(2): 251-263.Tatapania-a new genus of equisetalean fructifications, is represented by oblong-ovate bractless cones recorded fromthe Late Permian strata exposed in Banki Rivulet in Tatapani-Ramkola Coalfield, Chhattisgarh State, India. This is thefirst record of compact, conical and possibly terminal sphenophyte cones from the Lower Gondwana. The cones mayhave been related to Schizoneura gondwanensis as these are found in association with sterile equisetalean stems and leavesof Schizoneura gondwanensis in the same beds.Two new species, viz. Tatapania indica and T. obcordata, have been instituted for the genus. Both species closelyresemble cones of modern Equisetum. The presence of a compact cone similar to that of an extant Equisetum as early asLate Permian of Gondwana is interesting, especially when no member of Palaeozoic sphenophytes possessed suchcompact cones. The present find also supports the hypothetical model of Naugolnykh (2004a) wherein he proposed theevolution of the compact strobilus and peltate sporangiophore in modern Equisetum from the Late Palaeozoic ancestors.The double or single cones of Tatapania have been placed intermediate between Equisetites arenaceus with three conesattached together and Neocalamites carreri having single cone in the Naugolnykh’s evolution model of Equisetum. Areconstruction of Schizoneura gondwanensis plant having Tatapania cones attached on the apices of the leaf bearingbranches has been attempted.Key-words—Sphenophyte, Equisetales, Fructification, Peltate disc, Terminal cone, Late Permian.rkrkikfu;k uo oa'k] Hkkjr esa rkrkikuh&jkedksyk dks;yk {kss= ds Ik'p ifeZ;u ls izkIr lkbt+ksU;qjk xksaMokusfUllQkbLVesaVy dk ,d laHkkO; 'kadqdeythr flag] 'kSyk panzk ,oa vatq lDlsuklkjka'krkrkikfu;k&bDohlhVkyhu Qyu dk ,d uohu oa'k] rkrkikuh&jkedksyk dks;yk {ks=] NRrhlx

Modern pollen-vegetation relationship as an adjunct in theinterpretation of fossil pollen records in the Chilka Lagoon, Odisha, India. The Palaeobotanist 60(2): 265-271.In the present investigation, an attempt has been made to evaluate modern pollen-vegetation relationship in thesurface sediments of the Chilka Lagoon, Odisha. The ecosystem of the Chilka Lagoon has remained unique throughout itsexistence and the data generated from the analysis of surface sediments can be used for the interpretation of palynologicalresults in terms of past vegetation and climate around the Chilka Lagoon. The palynological investigations exhibited thedominance of midland taxa over the peripheral and fresh water taxa. The modern pollen-vegetation relationship asrepresented by the pollen spectra reflects the local and nearby vegetation in a consistent way. Core mangrove pollengrains were poorly registered in the pollen spectra as they are either absent or represented in a degraded form in the presentvegetation scenario. However, good representation of grasses showed a more or less close coherence with their actualcomposition in the present vegetation cover.Key-words—Modern pollen-vegetation, Palynology, Chilka Lagoon, Odisha.fpYdkySxwu] vksfM' k] Hkj r esat hok' e i j kx vfHkys[ ksadhO; k[; kesal gca/kds: Ikesavk/kqfud i jkx&ouLi frl aca/krkf' kYi kfl ag] c[ kZMZMCY; w- ' kQZ] vk' k[kaMsyoky ,oaeueksgu eksgarhl kj ka' k'ekSt wnkvUos"k.kesa] fpYdkySxwu] vksfM' kdsIk`"Bh; vol knksaesavk/kqfud i j kx&ouLi fr l aca/krkewY; kafdr djusdki z; kl fd; kx; kgSAfpYdkySxwudki kfj fLFkfrd ra= bl dhl ewphfon~; ekurkesavn~forh; j gkgSrFkIk`"Bh; vol knksadsfo'ys"k.kl sfudykvk¡dM+kfpYdkySxwu dspgqavksj xr ouLi fro t yok; qdsi j kxk.kfod i fj . keksaesafo'ks"k'kCnksal sO; k[; kgsrqi z; qDr fd; kt kl drkgSAi j kxk.kfod vUos"k. ksausi fj j s[kh; o vyo.kt y VSDl ki je/; ns'kh; VSDl kdhi zeq[krkfn[ kbZAi j kx Li sDVªkl s; Fkfu#fi r vk/kqfud i j kx&ouLi fr l aca/krkfLFkj : IkesaLFkuh; ,oavkl &i kl dhouLi fr i zfrfcafcrdj rhgSAi j kx Li sDVªkesaØksMeSaxzkso i j kx d.kvYi rkesant ZgSaD; ksafd osorZeku ouLi fr i fj n`'; esa; krksgSaugha] ; kde gSaAfQj Hkh] orZeku ouLi frvkPNknu usmudsokLrfod l a?kVu dsl kFk?kl ksadsvPNsfu: i .kusde ; kT+; knkl acn~/krkfn[ kbZAl aDsÿr&' kCn—vk/kqfud i j kx&ouLi fr] i jkxk.kqfoKku] fpYdkySxwu] vksfM' kA© Birbal Sahni Institute of Palaeobotany, India

Late Holocene vegetation, climate change and human impact in southwesternMadhya Pradesh, India. The Palaeobotanist 60(2): 281-289.Pollen analysis of a 2 m deep sediment profile from the dried Kachhar Lake, Sehore District, has demonstrated thatbetween 2050 and 1610 yr BP, open Acacia-scrub forest constituted of Acacia cf. nilotica, Grewia, Mitragyna, Sapotaceaeflourished in the region under relatively warm and humid climate with moderate monsoon precipitation, than that prevailstoday. The retrieval of fragmentary charcoals implies the repeated forest fire incidences. The presence of Cerealia andruderal plant taxa, viz. Cannabis sativa, Cheno/Am, Caryophyllaceae, etc. suggests the agricultural practices in the region.Between 1610 and 600 yr BP, Acacia-scrub forest turned profuse with expansion of Acacia cf. nilotica and otherarboreals, viz. Shorea robusta, Terminalia, Grewia and Madhuca indica in response to more-humid climate with the onsetof increased monsoon precipitation. Agriculture practice continued with same intensity as before. Since 600 yr BPonwards, the climate changed to less-humid as indicated by decline in Acacia-scrub forest.

Mid-Holocene vegetation shifts and climate change in the temperate beltof Garhwal Himalaya. The Palaeobotanist 60(2): 291-298.Pollen analysis of 3.06 m deep sediment core from the temperate lake-Nachiketa Tal, has brought out the vegetationshifts and climatic oscillations in the temperate region of Garhwal Himalaya since Mid-Holocene. The pollen sequencedepicts that between 5,304 and 3,912 yr BP the mixed conifer forests dominated by Pinus cf. wallichiana together withCedrus and Abies occupied most of the landscape under a regime of a cold and dry climate. The record of pollen of aquaticelement, Potomogeton and freshwater alga-Botryococcus implies the existence of the lake. The broad-leaved forestsmainly constituted of oak (Quercus cf. semecarpifolia) occurred sparsely in the moist and shady situations. Between3,912 and 2,975 yr BP the mixed conifer forests got transformed into mixed oak-broad-leaved forests as evidenced fromthe much expansion of Quercus and improvement of its close allies Alnus, Betula, Carpinus, Juglans, Salix, etc. Thischange in the vegetation pattern suggests that a warm and humid climate prevailed in the region. Around 2,975 to 1,872yr BP the abrupt decline in Quercus and its broad-leaved associates and a corresponding spurt in Pinus cf. wallichianareflect the re-establishment of pine dominated conifer forests with reversal of cool and dry climate. Subsequent expansionof Quercus and broad-leaved taxa around 1,872 to 767 yr BP and declining trend of conifers took place with theprevalence of warm and moderately humid climate. The sporadic encounter of Cerealia pollen during this phase indicatesthat the area was under cereal-based agricultural practice. Since 767 yr BP onwards a warm and less humid climate prevailedthan before and consequently relatively less-diversified mixed broad-leaved oak forests continued to thrive in the region,with relatively reduced frequencies of Quercus and other thermophillous broad-leaved elements.Key-words—Palaeovegetation, Palaeoclimate, Mid-Holocene, Nachiketa Tal, Garhwal Himalaya.x

Palynodating and correlation of subsurface sediments frombore-hole CMWY-95 of Wardha Valley Coalfield, Maharashtra, Central India. The Palaeobotanist 60(2): 299-307.Palynological studies have been carried out in the subsurface sediments of borehole CMWY-95 drilled near Pisagaonin Chandrapur District of Maharashtra. The studies have been aimed to palynologically date and correlate the sediments.On the basis of the statistical analysis of the spores and pollen from the productive samples, two palynoassemblages havebeen demarcated: Assemblage I recognised at a depth of 149.00 m is characterised by the dominance of the monosaccategenus Parasaccites and subdominance of Plicatipollenites which is typical of the Early Permian Upper Talchir palynofloraand Assemblage II identified between the depths 147.00-133.00 m is characterised by the dominance of Parasaccites andsubdominance of Callumispora which corresponds to the Early Permian Lower Karharbari palynoflora. Therefore,palynologically these sediments have been dated to be of Early Permian age.Further, within India, an inter and intra basinal correlation has been attempted while with the continents of theGondwanaland- Africa, Australia, Antarctica and South America, it is observed that the correlation with Antarctica isclosest when compared to other continents suggesting a closer genetic relationship with Antarctica. A close similarity withthe Early Permian palynosequences of Africa than that of Australia has also been noticed due to regional differencesamongst eastern and western Australia, while in South America correlation was feasible only in broader pattern of groupoccurrences as the differences were pronounced at finer levels.Key-words—Palynology, Gondwana, Karharbari, Barakar, Early Permian, Correlation, Wardha Valley Coalfield.o/ kZ?kVhdks; yk{ks=] egkj k"Vª] e/; Hkj r dsos/k&fNnzl h,eMCY; wokbZ&95 l si zkIr mi i `"Bh; vol knksadhi j kxk.kqvk; qfu/ kZj .k,oal gl aca/kegs' k,l -] i kWfyu l chukds- ,oa,y- egs' kfcYokl kj ka' kegkj k"Vªdspanzi qj ft ysesafi l kxk¡o dsut nhd os/ksx, os/k&fNnzl h,eMCY; wokbZ&95 dsmi i `"Bh; vol knksadki j kxk.kfod v/; ; u fd; kx; kgSAv/; ; uksadky{; vol knksadki j kxk.kfod : Ikl svk; qfu/ kZj .k,oal gl aca/kj gkgSA mRi knhuewuksal si zkIr cht k.kqo i j kx dsl kaf[; dh; fo'ys"k.kdsvk/ kj i j nksi j kxk.kql eqPp; i gpkusx, gaS%149.00 ehVj xgj kbZi j i gpkuhxbZi zFke l eqPp; ,dyl i qV oa'ki Sj kl SdkbV~l l si zHkohvkSjfIydsVhi kWysukbV~l l smi &i zHkohn~okj kvfHky{kf.kr gSt ksfd i woZi feZ; u Åi j rYphj i j kxk.kqi sM+&i kS/ ksadsi zfr: i hgSrFk147.00-133.00 eh- xgj kbZdse/; i gpkuhxbZn~forh; l eqPp; i Sj kl SdkbV~l l si zHkohvkSj dYyqfeLi ksjkl smi &i zHkohn~okj kvfHky{kf.kr gSt ksfd i woZi feZ;u fuEu djgjckM+hi j kxk.kqi sM+&i kS/ ksadsvuq: i hgSA vr%; svol kn i j kxk.kfod : Ikl si woZi feZ; u dky dsfu/ kZfj r fd, x, gSaA© Birbal Sahni Institute of Palaeobotany, India

Occurrence of the Genus Pachypteris in the Triassic of India. The Palaeobotanist 60(2):309-313.The leaf genus Pachypteris Brongniart occurs commonly in Mesozoic rocks throughout the world. In India, thegenus has hitherto been known only from the Lower Cretaceous strata of Rajmahal, Jabalpur, Bhuj and Pariwar formations.However, a few specimens collected from the Janar River beds of Tiki Formation, in their gross features and cuticulardetails, evidently represent a new species of the genus. The species, named as Pachypteris hirsuta sp. nov., in addition toits obvious hypostomatic lamina, is characterized by the presence of polygonal trichome bases. Each trichome base issurrounded by a ring of radially elongated cells.From Janar River beds, species of Lepidopteris, Dicroidium, Xylopteris, Sphenobaiera and Baiera have beendescribed earlier. Pachypteris is a further addition to this assemblage. On the basis of faunal and floral remains, TikiFormation has been dated as Upper Triassic. Occurrence of Pachypteris is hereby recorded for the first time from IndianTriassic strata.Key-words—Pachypteris, Tiki Formation, Upper Triassic, India.Hkj r dsVªkb,sfl d esai SdhIVsfj l oa' kdhmi fLFkfri adt ds- i ky ,oaekSferkcl ql kj ka' kl ewpsfo'o esae/; t hohpV~Vkuksaesai Rrhoa'ki SdhIVsfj l czk¡fXuvkVZl kekU; r%i k; kt krkgSAHkj r esavc rd ; g oa'kdsoy j kt egy] t cyi qj ] Hkqt,oai fj okj 'kSyl ewgksadsv/k%pkde; Lrj hesai gpkukx; kgSAfVdh'kSyl ewg dst uj unhl aLrj ksal sl ax`ghr dqNsd uewusmudsl exzy{k.kvkSj mi pehZfooj .k] oa'kdhuohu t kfr l qLi "V: Ikl s#i kf; r dj rsgSaAi SdhIVsfj l fgl qZVkuot kfr uked t kfr] vi uhl qLi "Vv/ ksj a/kzhi Vy dsvfrfj Dr] cgqHkqtRopkj kse vk/ kj ksadhekSt wnxhl svfHky{kf.kr gSAi zR; sd Ropkj kse vk/ kj f=T; r%nhf?kZr dksf'kdkvksadsoy; l sf?kj kgSAt uj unhl aLrj ksal sysfi MksIVsfj l ] fMØkWbfM; e] t k; yksIVsfj l ] LQsukscS,j kvkSj cS,j kdht kfr i gysof.kZr dht kpqdhgSaAbl l eqPp; esai SdhIVsfj lvkSj t ksM+hgSAi zkf.kt kr o i q"i hvo'ks"ksadsvk/ kj i j] fVdh'kSyl ewg dhvk;qÅi jhVªkb,sfl d ft ruhgSAHkj rh; Vªkb,sfl d Lrjhl si gyherZck,rnn~okj ki SdhIVsfj l dhi zkfIr vfHkfyf[kr dhxbZgSAl aDsÿr&' kCn—i SdhIVsfj l ] fVdh'kSyl ewg] Åi j hVªkb,sfl d] Hkj rA© Birbal Sahni Institute of Palaeobotany, India

Recognition of algal rich facies from the Umlatdoh Limestone of ShellaFormation, Jaintia Group, Meghalaya. The Palaeobotanist 60(2): 315-321.The carbonate rocks of the Shella Formation (Middle Eocene) belonging to the Jaintia Group in the Jaintia Hills ofMeghalaya are represented by two sandstone units in alternation with three limestone units, viz. Lakadong Limestone,Umlatdoh Limestone and Prang Limestone respectively in chronological order. Umlatdoh Limestone, the middle limestoneunit of Shella Formation is conformably underlain by the Lakadong Sandstone and overlain by Narpuh Sandstone. Samplesfrom the Umlatdoh Limestone were collected from the outcrop on the Jowai – Badarpur Road, about 1 km southwest ofLumshnong. Calcareous algae have been recovered from four samples and two distinct facies have been recognized. Oneof the facies is dominated by non-geniculate coralline red algae and benthic foraminifera. The non-geniculate corallinesare represented by Lithothamnion and Mesophyllum (Family Hapalidiaceae), Lithoporella (Family Corallinaceae) andSporolithon (Family Sporolithaceae). The other facies is rich in calcareous green algae along with benthic foraminifera.The green algal genera belong to families Dasycladaceae, Udoteaceae and Halimedaceae. Previously, a green algal assemblagewas recorded from the Umlatdoh Limestone Member of Shella Formation exposed in the low lying hills between Sutngaand Litang valleys of Jaintia Hills. However, this is the first report on the occurrence of non-geniculate coralline red algaefrom the Umlatdoh Limestone Member of the Shella Formation. Based on the algal-foraminiferal assemblages, interpretationhas been made on the palaeoenvironment and palaeobathymetry.Key-words—Algal rich facies, Growth-form, Taphonomy, Umlatdoh Limestone, Shella Formation, Jaintia Hills,Middle Eocene.t SafV; kl ewg] es?ky; ds' kSYyk' kSyl ewg dsmEyVnksg pwuki RFkj l si zkIr ' kSoky i zpqj l ay{kf.k; ksadhi gpkul qeu l jdkj] vfer ds- ?ks"k,oaek/ko dqekjl kj ka' kes?ky; dht SafV; ki gkfM+; ksaesat SafV; kl ewg ds'kSYyk'kSyl ewg ¼e/; vkfnuwru½dhi Sfy; kst hu dkcksZusVpV~VkusadkykuqØehØe esaØe'k%rhupwuki RFkj ,dka'ksauker%ykdkM¡kx pwuki RFkj ] mEyVnksg pwuki RFkj ,oai zax pwuki RFkj l fgr ,dkarj .kesarhu cyqvki RFkj ,dka' ksan~okj k: i kf; r gSaAmEyVnksgpwuki RFkj ] 'kSYyk'kSyl ewg dhe/; pwuki RFkj ,dka'kykdkMk¡x cyqvki RFkj l sv/k%' k; hvkSj uj i qg cyqvki RFkj l smi fj ' k; hdsl efoU; kl hgSAekSt wnkvè; ; u gsrqmEyVnksg pwuki RFkj dsuewusyE'kuk¡x l syxHkx 01 fdehnf{k.k&i f'pe t kWob&cnj i qj ekxZdscka, gkFkdhrj Qn`';ka'kl sl ax`ghr fd,x, FksApkj uewuksaesal spwusnkj 'kSoky feyhgSarFkorZeku ruq[kaMfo'ys"k.kesanksl qLi "Vl ay{kf.k; kai z: Iki gpkuhxbZgSaA,d l ay{k.khxSj &t kuqur i zokyhj Dr 'kSoky vkSj furyLFkQksj SfeuhQsj kl seq[; r%i zHkohgSAxSj &t kuqur i zokyhgsi yhfM,l hdqy dsfyFksFksfEu; u o ehl ksQk; Yye dht kfr] dksj yhuk,l hdqy dsfyFksi ksj sYykrFkLi ksj ksfy; k,l hdht kfr dsLi ksj ksfyFkWu dht kfr n~okj kfu: fi r gSaAvU; l ay{k.khi z: IkfuryLFkQksj SfeuhQsj kl fgr pwusnkj gfj r'kSoky esai zpqj gSAgfj r 'kSoky oa'kMsl hDysMsl h] mMksVh,l h,oagyhesMsl hdsl nL; gSaAi gyst SafV; ki gkfM+; ksadhl qrax ,oafyrax ?kfV; ksadse/; fupyhi gkfM+; ksaesavukofj r 'kSYyk'kSyl ewg dsmEyVnksg pwuki RFkj l nL; l s,d gfj r 'kSoky l eqPp; vfHkfyf[kr dhxbZFkhAfQj Hkh] ; g 'kSYyk'kSy l ewg ds© Birbal Sahni Institute of Palaeobotany, India

Palynological studies in the Lower Siwalik sediments of Nahan,Himachal Pradesh, India. The Palaeobotanist 60(2): 323-333.The present study highlights for the first time recovery of the Lower Siwalik palynoassemblage comprising algal,fungal, pteridophytic spores, gymnosperms and angiosperm pollen from an exposed section on Nahan-Ponta Saheb Road,Himachal Pradesh. The qualitative and quantitative analysis revealed that the algal and fungal spores are dominated byangiosperms, followed by pteridophytes and gymnosperms. The angiosperms show their maximum percentage in the totalassemblage. Algal remains are feeble in number. The important taxa recovered are: Psiloschizosporis microreticulatus sp.nov., Notothyrites sp., Lacrimasporonites barrelicus sp. nov, Lygodiumsporites lakiensis Saxena, Polypodiisporitesperverrucatus Nandi, Crassoretitriletes vanraadshooveni Germeraad et al., Todisporites kutchensis Sah & Kar, Pinuspollenitescrestus Kar, Araucariacites sp., Podocarpidites ruminatus sp. nov., Palmaepollenites kutchensis Venkatachala & Kar,Palmidites naviculus Kar & Saxena, Palaeomalvaceaepollis mammilatus Kar, Retimonosulcites circularis sp. nov.,Retitribrevicolporites nahanensis sp. nov., Ligulifloraedites pilatus Kar, Pseudonothofagidites kutchensis Kar, Meliapollisquadrangularis (Ramanujam) Sah & Kar. On the basis of their affinities with modern equivalents, a humid tropical to subtropicalclimate has been indicated encompassing some fresh water bodies during the deposition of these sediments in thisarea. The gymnospermous taxa (cf.

The present petrified flower was collected from well known fossiliferous localityMohgaonkalan, M.P., India, where Deccan Intertrappean beds are exposed. The previous diagnosis of the genus and thespecies is emended. The additional characters of Chitaleypushpam are especially about structure of carpels. In the presentfossil flowers gynoecia are seven carpeled and nine carpeled in Specimen-A and Specimen-B, respectively. Besides this, incross section the ovary reveals stellate structure. From the above discussion it is clear that present fossil flowers closelyresemble Chitaleypushpam mohgaoense Paradkar in many characters and hence are placed under the same genus andspecies with emended diagnosis.Key-words—Deccan Intertrappean, Angiosperms, Flower, Lythraceae.fprkysi q"i e eksgxkvksal i j kMdj dsKku esavkSj ; ksxnkui h-,l - dksdkVs] t h-oh- i kfVy] bZ-oh- mi k/; s,oavks-,l - l jkVsl kj ka' k; g ' ks/k&Ik= v'ehHkwr i q"Ikfprkysi q"i e eksgxkvksal i j kMdj dsvUos"k.kl aca/khgSrFki q"IkdsT+; knkl sT+; knkl aHko o.kZu dksi qu%of.kZr dj rkgSAorZeku v'ehHkwr i q"Ikl qi zfl n~/kt hok'ee; mi cLrheksgxk¡odyk¡] e/; i zns'k] Hkj r l sl ax`ghr fd; kx; kFkt gk¡nDdu var%Vªsfi ; u l aLrj savukofj r gSaAoa'k,oat kfr dki woZfunku l a' ksf/kr fd; kx; kgSAfprkysi q"i e dsvfrfj Dr vfHky{k.kfo'ks"kr%vaMi dhl aj pukdsckj sesagSaAekSt wnki q"Ikt hok'e esaØe'k%i zfrn'kZ, o i zfrn'kZchesat k;kaxh; l kr vaMi esa,oaukSvaMi esagSaAbl dsvykok] vaMk'k; vuqi zLFki fj PNsn esarkj kdkj l aj pukmn~?kfVr dj rkgSAmi ; qZDrfoospu l sLi "VgSfd ekSt wnki q"Ikt hok'e fprkysi q"i e eksgxkvksal i j kMdj l sdbZvfHky{k.kuksaesafeyrs&t qyrsgSavr%l a' ksf/kr funku l fgr ml hoa'k,oat kfr dsvarxZr fu/ kZfj r fd, x, gSaAl aDsÿr&' kCn—nDdu] var%Vªsfi ; u] vko`rcht h] i q"Ik] yhFksj sl hA

Gymnospermous woods from the Late Cenozoic sediments of Rajasthan, western India.The Palaeobotanist 60(2): 355-362.The paper describes two gymnospermous woods, namely Araucarioxylon Kraus, 1870 and Podocarpoxylon Gothän,1905 from the Late Cenozoic sediments (Shumar Formation) of district Jaisalmer, Rajasthan, western India. The woodsindicate favourable climatic conditions for the growth of mesic vegetation in Rajasthan till Plio-Pleistocene timecompared to the xeric vegetation and drier conditions in the area today.Key-words—Fossil woods, Araucarioxylon, Podocarpoxylon, Late Cenozoic, Jaisalmer, Rajasthan, India.Hkj r dsi fa' pehj kt LFku dsi ' p uwrut ho vol knksal si zkIr vuko`rcht hdk"Bsat s-,l - xqysfj; k,oavuqesgk' kqDykl kj ka' k; g ' ks/k&i = ft ykt Sl yesj ] j kt LFku] i f'pehHkj r dsi 'p uwrut ho vol knksa¼'kqej 'kSyl ewg½l si zkIr ,j ksdSfj vkWDl hykWu ØkSl ] 1870 ,oai ksMksdki ksZDl hykWu xksFku] 1905 uked nksvuko`rcht hdk"Bsaof.kZr dj rkgSAdk"Bsa] {ks= esavkt e#n~fHknhouLi fr ,oa'kq"dh; fLFkfr;ksadhrqyukesavfr&vR; aruwru l e; rd j kt LFku esaesfl d ouLi fr dhc

Occurrence of spore tetrads in the Pali sediments of South Rewa Basin, India and their climaticinference. The Palaeobotanist 60(2): 363-368.A group of spore tetrads with variable ornamentations have been recorded during the palynological analysis ofsubsurface Upper Pali sediments (Early to Middle Triassic), Sohagpur Coalfield, Madhya Pradesh, India. These tetrads areassignable to the form genera-Lundbladispora, Densoisporites, Lapposisporites and Verrucosisporites. It has been observedthat these spores were regularly released in unseparated tetrads indicative of failure to complete the normal processes ofspore development. This may be due to the anomaly in the temperature responsible for the non-dissolution of the callosewall which holds these spores in the form of tetrads. Occurrence of spore tetrads in certain group of plant community isa positive evidence which suggests that chronic environmental mutagenesis has taken place all over the world during theend Permian ecological crisis.Key-words—Palynology, Spore tetrads, Pali, Sohagpur Coalfield, Triassic, Gondwana (India).nf{k.khj hoknzks.kh] Hkj r dsi kyhvol knksaesacht k.kqprq"dksadhi zkfIr ,oamudkt yok; ohvuqekuj ke&vorkjl kj ka' kmi i `"Bh; i kyhvol knksa¼i zkjafHkd l se/; Vªkb,sfl d½] l ksgkxi qj dks; yk{ks=] e/; i zns'k] Hkjr dsi j kxk.kfod v/; ; u dsnkSj ku i fj orZuh; vyadj . ksal fgr cht k.kqprq"dksadkl ewg vfHkfyf[kr fd; kx;kgSA; sprq"d yqaMCykfMLi ksj k] Msafl vksLi ksj kbfVl ] ysIi ksfl Li ksj kbfVl ,oaos#ZdkWfl Li ksj kbfVl oa'ki zk#Ikdksfu; r gSaA i zsf{kr fd; kx; kgSfd cht k.kqfodkl dsl kekU; i zØe dksi w.kZdj usdsfy, foQyrkdsl wpd ; scht k.kqvfofPNUu prq"dksaesafu; fer : Ikl sfueqZDr gq, FksA ; g dSyl hdsxSj &foy; u gsrqmRrj nk; hrki eku esavl axfr dsdkj .kgSt ksfd bu cht k.kqvksadksprq"dksads: i esal aHkysj [krkgSAi kni l eqnk; dsfuf'pr l ewg esacht k.kqprq"dksadhi zkfIr l dkj kRed l k{; gSat kst rkrsgSafd vafre i feZ; u i kfj fLFkfrdh; l adVdsnkSj ku l ewpsl al kjesanh?kZdkyhIk; kZoj .kh; i fj orZu mRi fRr gqbZgSAl aDsÿr&' kCn—i j kxk.kqfoKku] cht k.kqprq"d] i kyh] l ksgkxi qj dks; yk{ks=] Vªkb,sfl d xksaMokuk¼Hkjr½A

Variations in Bennettitalean leaves of Indian Gondwana. The Palaeobotanist 60(2):369-376.The Bennettitales is a group of extinct seed plants characterized by pinnately compound crown of leaves whichoccur at the top of the stem and resembles cycads. These plants constitute a major portion of the Mesozoic vegetationand have a long geological history. The morphological variations in pinnate leaves exhibit primitive to advancedcharacters, i.e. simple to pinnately compound leaves with variable shapes, sizes and venation patterns. The interrelationshipsamong various genera of the group have been traced.Key-words—Bennettitales, Leaf Morphology, Variations, Mesozoic Gondwana, India.Hkj rh; xksaMokukdhcsusfVVsyh; i fRr; ksaesafofHkUurkuh: i zdk' k,oaek/ko dqekjl kj ka' kcsusfVVsYl ,d foyqIr i kni l ewg] ft l dsrusdsf'k[kj i j l fTt r fdj hVl erqY; fi PNkdkj i fRr; kal kbdsM~l l sl ekurkn’kZrhgSaA ; souLi fr; kae/; t hohdYi dsfo' ky Hkx dksl a?kfVr dj rhgSarFkvi usnh?kZHkw&oSKkfud bfrgkl dksi znf’kZr djrhgSaA bu fi PNkdkj i fRr; ksaesavkdkfj dh; fofHkUurk,avkfn: IkrFkmUur Lo: i ksavFkZr~i fj orZuh; : i ksa] vkdkj ksa,oaf'kj kfoU; kl i z: i ksadksi znf'kZr dj rhgSaAbl l ewg dsfofo/koa' ksaesavar%l aca/krkvksadkvuqj s[k.kfd; kx; kgSAl aDsÿr&' kCn—csusfVVsyht ] i Rrhvkd`frfoKku] fofHkUurk,a] e/; t hohxksaMokuk] Hkj rA
