The paper presents the results of an investigation carried out at the arboretum of Regional Research Laboratory, Bhubaneswar, Orissa, to find out the effect of pre-treatments on two exotic fast growing N2 fixing leguminous tree species. Pre-treatments with hot water and concentrated H2SO4 were found to hasten the germination rate from 80 to 85% in Enterolobium cyclocarpum and from 67 to 80% in Hymenaea courbaril. With out pre-treatment, the germination per cent was found to be nil. Fire scorching gave lower per cent germination i.e. 47 to 60% than the other treatments. Hot water is recommended as an effective and cheap pre-treatment for nurseries in Agro or Farm or Social forestry programmes.- Flora and Vegetation of Malkangiri District, Orissa, India - an Assessment

Extensive and intensive field surveys have been conducted in different forest pockets of Malkangiri with a view to assess the floristic wealth of the district. A sum total of 381 species belonging to 275 genera and 92 Families were collected, identified and incorporated. Out of these, 373 species represent Angiospermae (304 species of Dicot and 69 species of Monocot families), 7 species of Pteridophytes (7 species of Ferns belonging to 7 genera) and 1 species of Gymnosperms. The ratio of monocot to dicot families, genera and species are 1:4.25, 1:4.13 and 1:4.40 respectively. Present exploration enumerates 235 herbs, 51 shrubs, 69 trees and 26 climbers. Out of total 84 families of angiosperms, the dominant families in ascending order are Fabaceae, Poaceae, Acanthaceae, Asteraceae, Euphorbiaceae, Malvaceae, Caesalpiniaceae, Rubiaceae, Lamiaceae, Combretaceae, Cyperaceae, Mimosaceae, Amaranthaceae and Scrophulariaceae. Study highlights the rich floristic diversity of the district.Keywords

Phytochemical screening of 236 plant species from Orissa has shown the presence of tannins in 74, saponins in 14, flavonoids in 74 and alkaloids in 51 species. The presence of alkaloids in 13 species is reported for the first time. The tannin content of 32 species is found to be between 0.4 to 21.2 percent.- Phytochemical Screening of some Orissa Plants for Tannins, Saponins, Flavonoids and Alkaloids

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.- Floristic and Vegetational Analysis of Nabarangapur District of Orissa, India
