Geographical Distributions

Paspalum conjugatum is originated from the American tropics. It is then naturalised throughout Southeast Asia and in many tropical countries of the world. It is abundant in Indonesia, the Philippines and the Pacific Islands. [2]

P. conjugatum grows from near sea ­level up to 1700 m altitude in open to moderately shaded places. It is adapted to humid climates. It is found under plantation crops and also along stream banks, roadsides and in disturbed areas on a variety of soils, and often growing gregariously. [2]

Botanical Description

P. conjugatum is a member of the Gramineae family. It is a vigorous and creeping perennial with long stolons. [2]

The leaf sheath is strongly compressed, usually 30-50 mm long and ciliate on the margins. The ligule is collar-shaped and about 1 mm long. The leaf blade is linear or lance-shaped-acuminate, measuring 8-20 cm x 5-12 mm and hairless to sparsely hairy. [2]

The inflorescence is well exserted with two or occasionally three diverging racemes. It is 7-16 cm long. The spikelets are solitary, imbricate, flattened ovate, measure up to 2 mm long and with long hairs on the margins. The lower glume is absent while the upper glume is with a fringe of long hairs (1 mm) along its margin. [2]

The fruit is broadly ovoid, plano-convex, measures about 1 mm long and dark brown. [2]

The roots are at the nodes, with culms ascending to erect, measures 40-80(-100) cm tall, branching, solid and slightly compressed. [2]
