Abstract

Pachmarhi, a popular hill station of Madhya Pradesh, having in it the highest hill top (Dhupgarh) of central India, presents very interesting features in its flora. It has received attention by several botanists due to its popularity and importance from floristic point of view and a number of contributions to the flora were made by them (Gamble 1892, Graham 1914-15, Pandey & Srivastava 1952, Rao & Narayanaswamy 1960, Kapoor & Yadav 1962 and others). The present paper records 304 species of flowering plants and ferns, which are reported for the first time from Pachmarhi. Sixteen species are new records for Madhya Pradesh (marked by single asterisk) and twelve for central India (marked by double asterisk). The species, of which previous record was found to be based on wrong identifications have been excluded from the flora, namely Fimbristylis podocarpa Nees & Meyen, Arthraxon serrulatus Hochst., Arundinella nepalensis Trin., Eragrostis nutans (Retz.) Nees ex Steud., Sporobolus elongatus R. Br. and Tripogon pauperculus Stapf.

Abstract

Eighty three plant samples collected from the forests of erstwhile Kalahandi, Keonjhar, Koraput, Cuttack, Dhenkanal and Khurda districts of Orissa were screened for finding out new sources of therapeutically important active compounds. Tannins were found in 33, saponins in 4, flavonoids in 19 and alkaloids in 7 samples. Out of 83 samples screened, 40 samples belonging to 34 species were found to respond negatively for all the above ingredients. Garuga pinnata was found to contain 24.7% of tannins in its bark and the presence of saponins was recorded for the first time in the fruits of Eriolaena hookeriana.
