Discussion

Species 3 (3 in the flora).

Species of Hoita are known from streamsides to moist banks and humid wooded slopes of coastal mountains and foothills of the Sierra Nevada.

J. W. Grimes (1990) recognized only three species in Hoita, reducing four of the 11 species recognized by Rydberg to synonymy under H. macrostachya, transferring one to Otholobium C. H. Stirton, and three to Rupertia. Hoita in the sense of Grimes is distinguished from other genera of Psoraleeae by the presence of the extra, internal wall in the fruit, and it is the only genus of the tribe in which the calyx does not enlarge or change shape through flowering and fruiting. Separation of Hoita from other Psoraleeae is further validated by a molecular phylogenetic study of the tribe (A. N. Egan and K. A. Crandall 2008).
