BSIP Plant megafossils comprising leaf-impressions, fruits and fossil woods from Ghish River, Lish River, Sukha Nala and Sevoke Road cutting sections in the Himalayan foot-hills <strong>of</strong> Darjeeling District, West Bengal were studied. The leaf-impressions were identi fied belonging to modern angiospermous taxa-Xanthophyllum /lavescens, Pterospermum semisaggi/atum, Swin/oniafloribunda, Millettia albi/lora, Glochidion hirsu/um, Dipterocarpus tubercula/us, Shorea buchananii, Zizyphus apetala and Polyalthium longifolium. The fossil woods which form the first record from West Bengal Siwaliks, belong to modern taxa Bauhinia malabarica and Diospyros kurzii. The presence <strong>of</strong> these taxa indicates the existence <strong>of</strong> tropical climate with plenty <strong>of</strong> rainfall during Siwalik sedimentation as well as a fair exchange <strong>of</strong> floral elements between Malaya Peninsula and India. Visited the Himalayan foot-hills <strong>of</strong> Darjeeling District, West Bengal and a good number <strong>of</strong> well-preserved leaf-impressions, fruits and some carbonised woods were collected. Besides, Central National Herbarium, Howrah was visited for identification <strong>of</strong> fossil leaves collected from different localities <strong>of</strong> Bengal Siwaliks. Programme 9.12 : SEM studies on the pollen morphology <strong>of</strong> arborescent monocots <strong>of</strong> India with special reference to palms K. Ambwani In order to assess the affinities <strong>of</strong> fossil monocotyledonous taxa, SEM observations <strong>of</strong> the pollen <strong>of</strong> monocot taxa were carried out on: Areca catechu, A. triandra, RoyslOnea oleraceae, Iriatella setigera, Oncosperma tegillarium, Arenga engleri, Caryota mitis, C. urens and Cocos nud/era. SEM photomicrographs were also taken for their detai led interpretations. Studies on fossi I Sclerospenna-like pollen and the extant Sclerosperma manii were completed. Programme 9.13: Palynological studies on the Late Cretaceous sediments <strong>of</strong> central India R.S. Singh The spore-pollen recovered from areas around Jabalpur and Nagpur are scanty and mostly represented by pteridophytic spores. The assemblage from Lameta Formation from Nagpur includes Cicatricosisporites, Cyathidi/es, Todisporites, Appendicisporites, Ariadnaesporites and few pollen belonging to Palmae, whereas the Intertrappean sed iments apart from above have Tricolpites, Nypa and some porate-pollen. Maestrichtian marker genus Ariadnaesporites is found in both Lameta Formation <strong>of</strong> Nagpur and Intertrappean beds <strong>of</strong> Jabalpur area.
