TAYLOR, Nigel P  and  ZAPPI, Daniela C. Cactaceae of Jequitinhonha river valley (Minas Gerais). Acta Bot. Bras. [online]. 1991, vol.5, n.1, pp.63-69. ISSN 0102-3306.

During an initial visit to collect material for the projected "Cacti of Eastern Brazil", a remarkable great diversity of species of Cactaceae in the region of middle drainage of the Rio Jequitinhonha (mainly in the localities of Itinga, Itaobim and Pedra Azul) was noted. Twenty one species in the genera Pereskia, Opuntia, Tacinga, Pseudocanthocereus, Arrojadoa, Brasilicereus, Cereus, Coloecephalocereus, Melocactus, Pilosocereus e Selenicereus representing all three subfamilies of Cactaceae were recorted. The phytogeographic affinities of the Cactaceae from this region are discussed.

Keywords : Cactaceae; floristics; geographical distribution; Minas Gerais.
