General Information


Themeda arguens is a member of the family Poacea. It usually grows in tufts rather than solitary and reaches up to 120 cm tall with leaves mostly at the base. The leaf-sheaths of basal leaves are compressed, keeled, usually glabrous except at the junction with the blades. The upper sheaths are longer and rounded. Leaf-blades are linear measuring 5-30 x 0.3-0.8 cm; green or purplish in colour, flat or slightly folded in shape. The inflorescence of spatheate spike-like racemes arranged in flabelliform clusters from the ends or upper nodes. Each raceme subtended by a spatheate bract bears 1 sessile bisexual, each reduced to a single glume. Fertile spikelet with the upper lemma extended into a long twisted awn of 3.5-9 cm. The awn remains attached to the grain; it twists and untwists hygroscopically helping to bury the grain. [3]
