Abstract

RODRIGUES, Rodrigo Schütz  and  TOZZI, Ana Maria Goulart de Azevedo. A taxonomic revision of Leptolobium (Papilionoideae, Leguminosae). Acta Bot. Bras. [online]. 2012, vol.26, n.1, pp. 146-164. ISSN 0102-3306.  http://dx.doi.org/10.1590/S0102-33062012000100016.

This revision of Leptolobium Vogel includes an identification key, descriptions, illustrations, and distribution maps for the taxa. Leptolobium comprises 12 species, and is characterized by its arboreal or shrubby habit, flowers with white, actinomorphic or slightly zygomorphic corollas, 10 free stamens, a stipitate ovary with many ovules, indehiscent (samara-like or nut-like) fruits, compressed seeds, and a bulbose hypocotyl-radicle axis. Leptolobium is a neotropical genus that occurs from Mexico to northern Argentina. Eleven species are found in Brazil, seven of which are endemic to the country. The lectotype of Sweetia glazioviana Harms is designated in this paper. In addition, information about uses, common names, geographical distribution, and habitats are provided.

Keywords : Fabaceae; Sophoreae; genistoid clade; taxonomy; Acosmium.
