A rich palyn<strong>of</strong>loral assemblage has been recovered from the sub-surface Early<br />
Miocene sediments at Turavur in the Alleppey District, Kerala. 39 genera and 45 species<br />
belonging to different botanical groups, such as din<strong>of</strong>lagellate cysts, fungal remains_<br />
pteridophytic spores and angiospermous pollen have been recognized. A manuscript<br />
dealing with palynological findings and palaeoenvirorunent has been finalized.<br />

A rich palyn<strong>of</strong>loral assemblage mainly consisting <strong>of</strong> fungal spores and<br />
microthyraceous ascostromata, pteridophytic spores, gymnospermous and angiospermous<br />
pollen grains has been recovered from the Dharamsala sediments exposed along Bilaspur<br />
Shimla Highway near the village Karoda in Bilaspur District <strong>of</strong> Himachal Pradesh. The<br />
distributional pattem <strong>of</strong> palyn<strong>of</strong>ossils in the Dharamsala sediments has been analysed and<br />
interpreted throwing light on its dating and environment <strong>of</strong> deposition.<br />

Critical morphotaxonomie evaluation <strong>of</strong> pteridoph)tie spores recorded from Indian<br />
sediments \\as carried out.<br />
Samir Sarkar & J. P. MandaI<br />
Studied the morphology <strong>of</strong> various fossil genera showing affinity with modem<br />
A /angillm pollen reported from various Lower Tertiary sediments <strong>of</strong> India. Their characteristic<br />
teatures have been critically evaluated and compared with extant A/angillm.<br />

Forty-one samples were macerated from the bore-core 128 drilled by the MEC<br />
Ltd. at Mannargudi area, Tamil Nadu. Qut <strong>of</strong> these, 23 samples were productive. The pal)<br />
nologieal assemblage comprises pteridophytie spores and angiospermic pollen. Among<br />
the pteridophytie spores Cyathidite.\· minor, Lygodillmsporiles klltchensis and<br />
J'o/ypodiisporiles repandlls are common. The common species <strong>of</strong> angiosperms are<br />
PiladiporocoJpiles caratinii, Meliapo/lis ramanlljamii, Ctenolophonidile.\· coslallls,<br />
Tri/alisporiles klltchensis, Triangllioriles belills, Margocolporiles tSllkadai and<br />
Verrllcolporites vermclls. The assemblage favours an Early Eocene age for the sediments.<br />

To enhance the reference collections <strong>of</strong> modem plants in the <strong>Institute</strong>'s herbarium,<br />
about 700 plant specimens, wood samples <strong>of</strong> 10 species and 20 samples <strong>of</strong> fruits and seeds<br />
were collected and identified.<br />
Identification <strong>of</strong> about 200 plant specimens were done for the sponsored project<br />
investigated by Dr Asha Khandelwal <strong>of</strong> the <strong>Institute</strong>.<br />
