(Asclepiadoideae, Apocynaceae) from the semi-arid region of Brazil are decribed and illustrated: M. breviramosa (south-western Bahia) and M. nana (northern Minas Gerais). They are shrubs closely related to M. zehntgneri and, like that species are also associated with calcareous outcrops. The former can be recognised by linear leaves arranged in small, compact shoots and the latter is subshrub less than 50 cm high whose flowers are unique because of the adaxially villous corolla nd long-rostrate gynostegium. 4aBrasil 4aBahia 4aMinas Gerais 4aAsclepiadaceae 4aCaatinga 4aTaxonomía 4aSpecies Endangered0 tKew Bulletinx0075-5974gv. 66 n. 1 (2011)w238854  a(IBONE)81484246783  aAR-ReUNNbspacAR-ReUNNeaacr2
