Leaf anatomy of two genera of tribe Eragrostideae (Poaceae) from Mandal forest of Kedarnath wildlife sanctuary, Uttarakhand, India
Niteesh Kumar, S Nautiyal
The Poaceae is a grass family importantly covering all the cereals. The grasses are so vital in the economy of nations and particularly in an agricultural country like ours, where the provision of food and fodder is a constant problem for the populace and it is surprising that more time and energy have not been devoted to the study of the Poaceae. This tribe is characterized by unspecialized spikelets usually with several florets, 3-veined lemmas, and a rather cartilaginous texture, and also by a ciliate ligule, although there are exceptions to all these characters. Leaf anatomical investigations of two Generas belonging to tribe Eragrostideae (Poaceae) were carried out from. Maximum length of long cells was observed in genus Eragrostis. Microhairs with hemispherical distal cell, saddle shaped silica bodies and bulliform cells deeply penetrating the mesophyll are the diagnostic characters, which justify both the species in the same tribe.
