Contributions from the University of Michigan Herbarium 23: 83–105.0091-1860http://nrs.harvard.edu/urn-3:HUL.InstRepos:6620998Lophopterys Adr. Juss. is a South American genus of Malpighiaceae comprising seven species, two of which are described here as new (L. floribunda W. R. Anderson & C. C. Davis and L. occidentalis W. R. Anderson & C. C. davis). The taxonomic history, morphology, circumscription, and systematic position of the genus are discussed, with the conclusion that while the genus is coherent and easily recognized, its relationships in the family are still somewhat obscure. The taxonomy is revised with descriptions, keys, and notes on phenology, habitat, and distribution, and all specimens studied are cited. Illustrations include a distribution map, SEMs of pollen from two species, and drawings of six species.en-USJournal Article
