The ovary has 2 plumose (having feathers or featherlike growths) stigmas. The seed capsule is a strongly flattened caryopsis (grain).{{cite web |title=Urochloa trichopus (PROTA) |url=https://uses.plantnet-project.org/e/index.php?title=Urochloa_trichopus_(PROTA)&mobileaction=toggle_view_desktop |website=PROTA - Plant Resources of Tropical Africa |access-date=5 October 2023}} It flowers and fruits between June and August.

Urochloa trichopus

It was first published and described as Urochloa pullulans in D.Oliver & auct. suc. (eds.), Fl. Trop. Afr. vol.9 on page 589 in 1920, before later being called Urochloa trichopus.

It is class as Least Concern on the Red List of South African Plants.{{cite journal |last1=Raimondo |first1=D. |last2=von Staden |first2=L. |last3=Foden |first3=W. |last4=Victor |first4=J.E. |last5=Helme |first5=N.A. |last6=Turner |first6=R.C. |last7=Kamundi |first7=D.A. |last8=Manyama |first8=P.A. |title=Red List of South African Plants. |journal=Strelitzia |date=2009 |volume=25 |publisher=South African National Biodiversity Institute |location=Pretoria}}
