Taxonomie : "It seems likely, but not demonstrable from hard evidence, that an earlier name for var. unijuga is M. pudica β glabrata DeCandolle, Prodr. 2: 426. 1825, based on Mimosa humilis, frutescens et spinosa, siliquis conglobatis Plumier ex Burman, Pl. amer. fasc. 9: t. 202. 1759, "in ins. Sancti-Domingi et Sancti-Thomasii." —All modern collections from Hispaniola that I have seen represent var. unijuga, the dominant form of the species throughout the Antilles, as do all the five known collections from St. Thomas. However, Plumier's plate, at least in Burman's reproduction, lacks the fine detail on which varietal identity hinges, and I therefore follow Brenan in discarding var. glabrata as ambiguous" (Barneby 1991).
