To build up the floristics for interpretillg palaeoecology, phytogeography<br />
alld evolutionary pallerns <strong>of</strong> the Himalayanflora<br />
A number o[ leaf-impressions, collected from the Himalayan foot-hills near<br />
Oodlabari and Sevoke Road cutting section in DaJjeeJing District, have been identified with<br />
the modern taxa Mitrephora macrophylla, Polyalthia simiarum, Milletia pachycarpa, Shorea<br />
Imchall(lnii, Phyllanthus hirstum, Swintonia floribunda, L(lgerstroemia collelli and<br />
/)ipreroc(lrpus macrocarpus. The OCCUlTence<strong>of</strong> these elements in the Siwalik sediments<br />
indicates the prevalence <strong>of</strong> waJ'm and excessive moist conditions in the aJ'ea at the time o[<br />
sedimentation.<br />

Collection <strong>of</strong> extant plant material from the foot-hills <strong>of</strong><br />
Himalaya<br />
Objective To enhance the collection <strong>of</strong> extalll plant material and their<br />
preparationsfor development <strong>of</strong> Herbarium <strong>of</strong> the fnstitute as<br />
repository <strong>of</strong> the authentic plant specimens alld samples<br />
To provide (I11/helltieally idel1lified extallt plant material to<br />
rhe scientists as per their requirements<br />
Preparatioll <strong>of</strong> fnventol)' and Atlases <strong>of</strong> Herbarium holdings<br />
About 600 plant specimens and eighty samples <strong>of</strong> fruits and seeds have been collected<br />
[rom Allahabad, Raibareilly and Llicknow in Utta;' Pradesh and Kaltli, Jabalpm,<br />
Scorn and Balaghat districts in Madhya Pradesh and their identification was completed.<br />
Preparation o[ Inventory <strong>of</strong> HerbaJ'ium holdings (Carpothek and XylaJ'ium) is under<br />
progress. Prepared about 2,000 cards <strong>of</strong> XylaJ'ium [or computer [ceding. Physical verilication<br />
<strong>of</strong> wood samples present in the HerbaJ'ium has been completed.<br />
HerbaJ'illITIhas been shifted to the hall originally meant for it, repository has been<br />
re-aJTanged and exllibits aJ'e being displayed.<br />
