Abstract
Six native and 1 naturalized speices of Fuchsia (Onagraceae) from Mexico and Central America are recognized, not including the recently revised sect. Encliandra. One species, F. jimenezii, sp. nov., and one section, Jimenezia, are newly described, and Ellobium is also recognized as a section. The recognition of subdioecy in F. paniculata (sect. Schufia) now strengthens evidence of a trend toward male sterility and eventual dioecy in the small, peripheral sections of the genus. The distinctions between that species and the closely related but entirely hermaphroditic F. arborescens are established. F. jimenezii (sect. Jimenezia) is a phylogenetically key species because it has the antipetalous stamens reflexed into the tube like sect. Encliandra, yet it has the more generalized many-seeded berry and hermaphroditic flowers of most other sections. The new sect, Ellobium joins F. splendens, F. fulgens and F. decidua into a morphologically and geographically coherent unit, with links to the Andean sects. Fuchsia and Hemsleyella. F. cordifolia is reduced to the synonymy of F. splendens on the basis of a study of populations from throughout its range.
