Para Grass - Urochloa mutica
Family: Poaceae

THIS PAGE IS UNDER CONSTRUCTION.

Description

Urochloa mutica is a robust, stoloniferous perennial that may be as much as 1 m or more tall. The lower portion of the stem is decumbent and roots at the nodes. Nodes of the stem are swollen and have dense hairs. The leaf sheath also has hairs that are often deciduous with age. Leaves are up to 30 cm long and 10 to 15 mm wide. The ligule is a collar of short stiff hairs. The inflorescence is a primary axis with alternately arranged "branches" that have numerous spikelets. Spiklets are subsessile and about 3 mm long with a purple tint.

Interesting facts

Para grass reproduces from seed and vegetatively by creeping stolons. It often grows in cultivated or disturbed areas with moist soil. Once established, it can spread horizontally by floating stolons into shallow water areas of lakes, ponds, and streams and form dense, floating mats (Tarver et al. 1986, Hoyer et al. 1996).

Floating mats of para grass can impede water flow in drainage ditches and irrigation canals, and restrict recreational activities and navigation in shallow water (Tarver et al. 1986, Hoyer et al. 1996).
