Conteúdo: | In the "cerradoes", or xeromorphic forest, remaining alongside the road Belo Horizonte- Brasilia, we found a small leguminous tree which yielded latex when its leaves or branchie- ts we wounded. Since it was recognized as a Mimosa species, the presence of latex is a remarkable peculiarity and the same holds true for the makedly corky bark, very thick as well as soft. This charater, associated with leathery, hairy folioles, leads to the conclusion that the present tree represents the first genuine Mimosa species for the "cerradao". The closest species is Mimosa obovata Benth., very similar to the one referred to above if only dried material is to be considered. Notwithstanding, the living specimens are quite different M. obovata is large liana, devoid of latex and covered with a thin cortex. A few other sma- ller differentes can be noted, such as leaf vesture, nervation, etc. It is worth noting that herbarium material of Mimosa laticifera had been already sent to Burkart (according to his own information) some 17 years ago by AMARO MACEDO, from Ituiutaba (Minas Gerais).
