The seeds of Hedychium spicatum, an important medicinal herb were treated with six different concentrations of Gibberellic Acid (GA3) as pre-sowing treatments viz., GA3 100ppm, GA3 200ppm GA3 300ppm, GA3 400ppm, GA3 500ppm and GA3 600ppm and untreated control to study their effect on germination and seedling vigour index. Significant differences were observed in germination percentage and seedling vigour index of H. spicatum treated with different pre-sowing treatments. Maximum germination of 98 per cent was recorded in seeds treated with GA3 400ppm followed by 91 per cent germination in seeds treated with GA3 300ppm, 90.33 per cent germination in seeds treated with GA3500ppm and 88.00 per cent in seeds treated with GA3 600ppm. Minimum germination of 74.33 per cent was recorded in seeds which were not given pre-sowing treatment. Similarly, maximum seedling vigour index (561.85) was also recorded in seeds treated with GA3 whereas, minimum seedling vigour index (422.40) was recorded in untreated seeds. Therefore, seeds of H. spicatum should be treated with GA3 400ppm before sowing in the nursery for better germination and seedling vigour.

The paper deals with 20 species of plants used for ear problems by the tribes of Adilabad district, Andhra Pradesh. Neptunia oleracea and 15 practices were found to be new.

Poor viability of spores and germination and slow growth in conventional vegetative propagation are major constraints in the in vitro culture of Asplenium aethiopicum, an important medicinal fern. In the present study, a procedure for in vitro propagation of this endangered fern through croziers has been established. Maximum sporophytes efficiency was obtained on KC media supplemented with growth regulators such as 0.5 mg/l NAA & 0.5 mg/l 2,4-D with 2 sucrose under photoperiod condition. Maximum frequency (33.2%) of callus formation and germination of sporophyte was observed on KC medium with growth regulators.

A new variety of Syzygium caryophyllatum is described and illustrated.

The paper deals with 35 species of plants used by the tribes of Khammam district, Andhra Pradesh, for curing boils, burns and bruises. Leaf is used in maximum of 16 practices. Gyrocarpus asiaticus and 23 practices were found to be less known.

The preliminary investigations on crude resources of drugs used by Sugali tribes of Nallamada Mandal, Anantapuramu district, Andhra Pradesh with their recipes, preparation of drugs, administration, and usage from several centuries. 63 crude drug yielding species belonging to 31 families were collected based on folk-lore knowledge. Scientific names, first time provided Sugali vernacular names, family name, part used, photographs, mode of preparation and administration and purpose, for which it has been used were enumerated.

The present floristic account of Nandhaur Wildlife Sanctuary (NWS) is mainly concerned with flowering plants and provides first hand comprehensive information. Statistical analysis of the floristic diversity of Nandhaur Wildlife Sanctuary through intensive plant collection revealed that, it is composed of 112 families (Dicots-92 and Monocots-20), 662 species (Dicots-516 and Monocots-146), including infra-specific taxa and also some cultivated species of the angiosperms. The proportion of the dicots and monocots is 3.6: 1, where, Poaceae stands as largest family having 48 genera with 71 spp., followed by Fabaceae with 34 genera and 62 spp. Genus Cyperus with 13 spp. in monocots and Crotalaria with 8 spp. in dicots stand as largest genera in the sanctuary.
