Abstract
Dichanthium is one of the dominant genus of family Poaceae. Locally called marvel. Flora of Buldhana district has been already studied by Diwakar and Sharma (2000). During last 24 years no survey was conducted of the area. It is Perennial grasses, tufted, leaves narrow, linear leaves with a smooth or slightly rough texture. Inflorescence Panicle-like or raceme-digitate or subdigitate, flowering structures with spikelets. Many species are used as grazing and are drought-tolerant, flourish in arid and semi-arid regions
During present study visited to the different areas of Buldhana district and 4 different species of Dichanthium have been collected. i.e. D. annualatum, D. pertusum, D. caricosum, and D. foveolatum. During collection field diary has been maintained. Field characters such as density, frequency, height, habitat, etc. were recorded. After collection specimens were dried with the help of plant presser. After drying specimens were mounted on herbarium sheets by stiching. After preparation of herbarium all specimens were observed under stereoscopic binocular microscope. Spikelets were dissected, glumes, lemmas, palea were observed; specimens were identified with the help of standard floras i.e. Grasses of Maharashtra by Dr. G. G. Potdar et al., Grasses of Marathawada by Dr. B. W. Patunkar, Flora of Marathawada by Dr. V. N. Naik, Flora of British India by Hooker, and all available literature. After identification all the specimens were discribed on the basis of actual specimens, during description all the vegetative as well as floral characters were covered.
Keywords: Dichanthium, Spikelets, Herbarium, Flora, Sterioscopic Binocular.
