Description 

Polypogon schimperianus (Hochst. ex Steud.) Cope is a tropical grass. It is a caespitose, tufted perennial grass, which grows to a height of 30-75 cm. Culms are geniculate, ascending or decumbent, 30-120 cm long. Leaves are 6-15 cm long x 3-5 mm wide. The leaf-blade surface is rough. Flowers are borne in a linear, contracted panicle, 6-20 cm long and 0.6-2.5 cm wide (Clayton et al., 2006). Information on Polypogon schimperianus is almost non-existent. It has been considered "data deficient" for the assessment of its status for the IUCN Red list of threatened species (Lansdown et al., 2013).

Distribution 

Polypogon schimperianus is native to a relatively small area of East Africa, from Zambia north to Rwanda and Ethiopia, with a small population confined to the highlands of the western escarpment in Southern Saudi Arabia and Western Yemen. It grows in swamps, usually as low growth between larger tufts of coarse grasses and sedges. It competes poorly with other grasses. It grows at an altitude between 1800 and 2900 m (Lansdown et al., 2013).

Nutritional aspects
Nutritional attributes 

The only sample available in the literature indicates a high protein content of 18% of DM (Dougall et al., 1958).

Ruminants 

Polypogon schimperianus has been described as well grazed and with a high feeding value (Dougall et al., 1958).
