Type in the U. S. National Herbarium, No. 2046312, collected in flood-plain forest at Cerrejón, Department of Magdalena, Colombia, 100 meters altitude, December 3, 1949, by Oscar Haught (No. 6729).

Justica leucerythra bears a general resemblence to the Peruvian species J. glabribracteata Lindau., but in that species the bracts are relatively broader and often obtuse or rounded instead of sharply acute, and the capsules are more or less hirtellous. The specific epithet is from the Greek λevrépupos, meaning pink, in allusion to the pink corollas.
