Discussion
(Plate CXXV)
The var. carthagenensis is variable in pubescence. Modern collections from prov. Bolivar in Colombia, whence the original Psoralea carthagenensis is thought to have come, are glabrous up to the spikes, as are the specimens in Jacquin’s herbarium preserved under the latter name. The same glabrous form occurs on Curaçao, but the populations sampled from stations in Santa Marta have thinly pubescent leaves and branchlets, intermediate to the usually villosulous Venezuelan plant to which the name Psoralea emphysodes was originally given. The few records from the Magdalena valley in Colombia are likewise more or less pubescent.
The representatives of D. carthagenensis found on Hispaniola, which Clausen referred, together with our var. floridana, to a subsp. domingensis, thought to differ in hooked calyx- teeth, is scarcely different from the villous phase of the South American mainland. The teeth in the holotypus of D. domingensis are, moreover, straight, and in other collections seen from Hispaniola almost imperceptibly incurved distally. On the other hand it seems preferable to exclude from var. carthagenensis the Porto Rican elements assigned by Rydberg to Parosela emphysodes; these have the habit and glabrous foliage of strictly typical var. carthagenensis but differ consistently in their smaller flowers. Curiously, the one collection that I have seen from the Virgin Islands is not var. portoricana, but typical var. carthagenensis.
