U. guyanensis is native to Central (Honduras and Nicaragua) and South America (Brazil, French Guiana, Guyana, Suriname, and Venezuela). It grows as a terrestrial plant on wet or damp sandy savannas at lower altitudes, but up to 1,100 m (3,609 ft) in Bolívar. It has been collected in flower between January and November. It was originally published and described by Alphonse Pyrame de Candolle in 1844 and placed in its own section, Stylotheca.
