Geographical Distributions

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


Paspalum conjugatum is a vigorous and creeping perennial with long stolons. It roots at the nodes, with culms ascen­ding to erect, measures 40-80(-100) cm tall, branching, solid and slightly compressed.

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.

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.

This grass fruit is broadly ovoid, plano-convex, measures about 1 mm long and dark brown.

Ecology / Cultivation

Paspalum 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, often growing gregariously.
