Racemes short-pedunculate; peduncle shorter than corresponding petiole; boat-shaped floral bracts sessile, without markings, ovate, margins entire, hispid. Flowers: calyx 3–5 mm; petals 7–11 mm. Mericarps 3 mm, smooth with reticulate veins, minutely puberulent to pubescent.
Phenology: Flowering year-round.

Elevation: 0–500 m
Distribution
Fla., West Indies (Cuba, Puerto Rico).
Discussion
The name Malachra fasciata Jacquin is sometimes misapplied to M. urens, but the former is white-flowered rather than yellow-flowered, and differs in other characters, as noted by F. Areces B. and P. A. Fryxell (2007).
Selected References
None.
