Leucophyllum (Greek, while leaf). Scrophulariaceae. Three spreading shrubs in Texas and N. Mex. with small alternate, elliptic to obovate entire leaves covered beneath with silvery white wool: flowers axillary; calyx 5-parted; corolla campanulate or funnelform, with 5 rounded spreading lobes; stamens 4, didynamous, included, fixed at the base of the corolla; ovary 2- celled: caps. 2-valved; seeds many, oblong, wrinkled. Only the following species is cultured in S. Fla., and deserves cultured everywhere in the S. According to C. S. Sargent, "There is no shrub of the desert portions of the valley of the lower Rio Grande more generally distributed, and certainly there is not one of them which more delights the traveler in the early spring months, when the large, violet-purple flowers of this plant heighten the effect of its brilliant silvery foliage."
