Two new species of Athenaea Sendtn. (Solanaceae) from the Brazilian Atlantic Forest are described and illustrated. Athenaea altoserranae I.M.C. Rodrigues & Stehmann, sp. nov. from the Serra do Mar range, in São Paulo State and Athenaea hunzikeriana I.M.C. Rodrigues & Stehmann, sp. nov. from a restricted area in the north-eastern region of Minas Gerais State and the southern part of Bahia State. Both species have brown to purple-brown or purple mature fruits, a character not found in other species of Athenaea. Descriptions, illustrations, complete specimen citations and maps of both species are provided. A dichotomous key to all species of Athenaea is also presented.

Portulaca hirsutissima (Portulacaceae) is a succulent herb occurring in open fields, sandy or rocky soil of separate Brazilian areas. On the basis of the analyses of seeds and pollen grains macro- and micromorphology, a significative variation, which is related to the distribution pattern, was found. Two new species are here proposed, described and illustrated. Portulaca giuliettiae sp. nov. occurs in Eastern Brazil, from Paraiba to Rio de Janeiro and P. goiasensis sp. nov. is restricted to the Chapada dos Veadeiros, in Central Brazil. P. hirsutissima is now to be considered as a restricted species from Minas Gerais State. A lectotype for the name P. hirsutissima is designated from a specimen preserved at P.

Two new species of Astyanax are described from eastern Brazil: A . microschemos from the córrego Palmital, rio Itapemirim drainage, Espírito Santo, and A . pelecus from the rio Pardo drainage, Bahia. Astyanax microschemos differs from its congeners by its shallower body depth, 26.9-29.7% of standard length, the presence of one vertically elongate humeral spot that extend above and below the lateral line, smaller interorbital width, 26.9-30.4% of head length, and the possession of 14-18 branched anal-fin rays. Astyanax pelecus differs from its congeners in the possession of only one humeral spot limited to the region dorsal to the lateral line, conspicuous, dark, midlateral body stripe extending from the upper margin of the opercle to the caudal-fin base, a shallower body depth, 26.7-34.8% of standard length, and the possession of 16-18 branched anal-fin rays, 38-39 scales in the lateral-line series, and four scales between the lateral line and the pelvic-fin origin. Astyanax microschemos has a massive head, short snout, usually smaller than the orbital diameter, shallow body depth, and vertically-elongate humeral spot that serve to include it in the A . scabripinnis species complex. A comparative synopsis of this complex is provided.

Two new species and one new nothospecies of Tacinga from semi-arid Eastern Brazil are described. The new taxa were discovered on the basis of material collected during field trips carried out by staff of the Cactarium Guimarães Duque of the Instituto Nacional do Semiárido. A morphologic comparison of all the Tacinga species currently known, together with the cytogenetic analysis of the new taxa, are made. Full descriptions, illustrations, taxonomic discussions for all three new taxa are given as well as an identification key for all known Tacinga species. IUCN categories for the new taxa were assessed, resulting as endangered or critically endangered, due to their small population size and restricted distribution.
