Abstract:
Foliar anatomical investigations of some members belonging to tribe
Eragrostideae (Poaceae) were carried out. In total of 8 species
belonging to 6 genera were collected in wild from Salt Range region of
Pakistan for anatomical studies. Maximum length of long cells was
observed in genus Eragrostis. Macrohairs are found absent in all
species except Eragrostis papposa. Acrachne racemosa is
identified by dumb bell shaped or cross shaped silica bodies while
saddle shaped silica bodies are present in other species.
Desmostachya bipinnata is distinct by having a tall girder of
bulliform cells, from adaxial to abaxial side. Microhairs with
hemispherical distal cell, saddle shaped silica bodies and bulliform
cells deeply penetrating the mesophyll are the diagnostic characters,
which justify all the species in the same tribe.
