Abstract

Phytosociological studies of grassland communities of Southern Aravalli Hills of Rajasthan are reported in the present communication. It was observed that Heteropogon contortus and Sehima nervosum are more frequent on plain and hillock areas of grassland communities respectively. Heteropogon contortus had the highest density (98.4 individuals/m²) on plain area and Aristida funiculata had the highest density (104.8 individuals/m²) on hillock area. Aristida funiculata was most abundant grass on plain as well as hillock area. Maximum importance value index was shown by Heteropogon contort us and Aristida funiculata on plain and hillock area respectively. The high value (0.047) of dominance index was recorded on hillock area, while low value (0.039) on plain area. Diversity index was found to be negatively correlated (r =-1.00) with dominance index.

Abstract

Ethnobotanical survey among the tribals inhabiting Southern Rajasthan brought to light a number of wild plant species used as edibles. The plant parts, viz., tubers, stems, leaves, flowers, fruits and seeds are used in raw or cooked form. The health, vitality and longevity enjoyed by the tribals have been attributed by them to these wild edibles. However, most of the tribals today are deprived of their traditional food choice due to depletion of forest resources and destruction of forest areas. These tribals are malnutritioned and are susceptible to many diseases. This paper enumerates and discusses various aspects of the contribution of some wild edible plants in the diet of tribals of Southern Rajasthan.

Abstract

The biological spectrum of protected and grazed watershed areas of South Rajasthan, reveals that the vegetation of this area is Therophytic. Total 98 species were present in the study area. The life forms observed in protected site were Phanerophytes (16.4%), Chamaephytes (3.5%), Cryptophytes (18.8%), Hemicryptophytes (2.4%) and Therophytes (58.8%), while in grazed site were Phanerophytes (3.5%), Chamaephytes (5.3%), Cryptophytes (19.6%), Hemicryptophytes (3.5%) and Therophytes (67.8%). The percentage of Therophytes and Cryptophytes is higher in comparison to Raunkiaer's normal spectrum. The higher percentage of Therophytes in grazed site is due to biotic interferences particularly due to grazing by cattle.

Abstract

Hitherto unreported folk medicinal uses of 41 species of plants belonging to 29 families used by the tribals of Southern Rajasthan have been dealt in this paper. Some plants with important ethnomedicinal new uses are Aegle marmelos, Leucas aspera and Pongamia pinnata in migraine; Acacia leucophloea as contraceptive; Borassus flabelifer, Grewia orientalis and Ziziphus xylopyra in developing complete sterility in female while Cocculus villosus in male; Citrus medica in kidney stone; Crinum asiaticum in breast cancer; Cryptolepis buchanani in piles; Gardenia turgida and Luffa acutangula as antidote in animal bite; lchnocarpus frutescens in swollen gums; Lannea coromandelica in earache; Nyctanthes arbortristis in obesity; Euphorbia acaulis, Grewia dumine, Xeromphis spinosa in skin diseases and Clitoris ternatea in colic.
