| Abstract: | Abstract. Galphimia (Malpighiaceae, Byrsonimoideae, Galphimieae) comprises 26 species of
suffrutescent herbs, shrubs, and treelets. Four species (G. amambayensis, G. australis, G. brasiliensis, G.
platphylla) occur in South America south of the Amazon basin, and the remainder in Mexico; one species
(G. angustifolia) extends into Texas and one (G. speciosa) into Central America. One species, G. gracilis,
is cultivated worldwide in warm regions. The genus is characterized by bilaterally symmetrical flowers
with yellow to red petals; in eight species the petals are persistent. The sepals lack oil glands, but a few
species bear calyx glands that resemble the leaf glands. The fruit is a globose schizocarp breaking apart
into three small 1 -seeded cocci. The base chromosome number is x=6. For each species a full synonymy,
detailed description, and range map are provided; all but two species are illustrated. Three new species
(G. calliantha, G. floribunda, G. speciosa) are proposed. |
