Bothriochloa pertusa

This is a perennial grass that spreads via stolons. centimeters tall. At times they may extend along the ground for a distance, rooting where stem nodes contact the soil. The leaves are up to 30 centimeters long; the upper leaves longer than the lower. ==Habitat==

In general, it requires tropical climates, and it does not tolerate frost. It is able to grow in many types of soils. It withstands drought and disturbance, and it can sprout up in dry, degraded habitat, such as roadsides. It survives short-term waterlogging and fire. ==Human uses==

This grass is used as a lawn, as it can form a dense mat. It is occasionally seeded in landscaping projects, along roadsides and in degraded fields, for example. It tolerates trampling, grazing, and cutting. In heavily grazed fields it is favored, becoming dominant as other grasses are eliminated by grazing pressure. Palatability is reduced when the grass flowers. Cultivars include 'Ghana Marvel 20', a high yield type developed in India, and the rust-resistant 'Dawson', 'Keppel', and 'Medway' from Queensland. It is sometimes planted with companions such as the grasses Cenchrus ciliaris, Urochloa mosambicensis, and Digitaria didactyla, and legumes such as Centrosema pascuorum, Chamaecrista rotundifolia, and Lotononis bainesii. ==Ecology==

A widely introduced species, it has become naturalized in many regions, and at times has become a noxious weed. It has been especially difficult to control in the Virgin Islands. ==References==
