Description
Urochloa texana has fibrous roots and leaves finely pubescent on both sides, with pubescent sheathes and a split sleeve. The ligules are membranous and fringed with dense trichomes. The plant forms simple inflorescences 7.0–25.0 cm (2.8–9.8 in) in length.[4]
In habit, Urochloa texana is decumbent or creeping up to 80.0 cm (31.5 in) tall. It is found commonly in areas such as cultivated areas, pastures, fields, roadsides.[4]
Distribution
Ecology
Urochloa texana is considered a crop weed.[4][5][6] The weed is especially problematic in peanut cultivation[5] as the tight, fibrous roots of the plant intertwine with the crop. This can cause peanut pods to be stripped from the plant during harvesting, and can also slow the drying process.[7]
The plant utilizes C4 carbon fixation.[8]
