Números cromossômicos em espécies de Acosmium Schott e Leptolobium Vogel (Leguminosae, Papilionoideae)

Morphological and micromorphological characteristics of Desmodium fruits (Leguminosae: Papilionoideae).

The genus Desmodium is represented in Santa Catarina State, Brazil, by 13 species, all with lomen- taceous fruits. Shape, size and isthmus margin of loments vary, while the surface is glabrous, or covered by trichomes of different types. Morphological diversity of trichomes becomes particularly relevant to taxonomic description. The trichome types present on the surface of Desmodium fruits prov...
