Eremanthus praetermissus and E. ovatifolius, two new species from Brazil, are here described and illustrated. Eremanthus praetermissus is endemic to Serra do Mar, in the northeastern part of São Paulo state and the southern part of Rio de Janeiro state; it is characterized by hemispherical, brown syncephalia, heads connate for 1/3 to 2/5 of their length, with 3–4 florets per head and brown phyllaries with purple apices. Eremanthus ovatifolius is endemic to campos rupestres of Pico da Aliança, in the eastern part of Minas Gerais state, and is characterized by ovate leaves, hemispherical syncephalia, heads connate for 1/4 to 1/2 of their length and 3–4 florets per head. The affinities of these species are discussed. A key to all species of Eremanthus is provided.

Three New Species

Encholirium is an exclusively Brazilian genus of Bromeliaceae that occurs principally in the South American dry diagonal, with only a few species found on inselbergs within the Atlantic Forest. The center of diversity of the genus falls within the Campos Rupestres of the Espinhaço Range of the state of Minas Gerais, followed by rocky outcrops found within the Caatinga and Cerrado biomes. Three new species are described and illustrated, two of which occur on limestone outcrops in western Bahia (Encholirum splendidum and Encholirium fragae), while the third, Encholirium kranzianum, occurs in the Campos Rupestres of the Espinhaço Range of Minas Gerais.

Two New Species

Two new species of Pseudotrimezia are described and illustrated. Both species are endemic to localities of “campos rupestres” in Diamantina Plateau, Minas Gerais State, Brazil. Pseudotrimezia nana is remarkably distinguished by the overall size, one of the smallest within the genus, bracts on the flowering stem and leaf anatomy. Pseudotrimezia striata is noteworthy due a partly bifacial leaf that encloses the flowering stem. Morphological comparisons with similar species are also provided.

Centers Of Endemism

Abstract—We describe and illustrate Stenandrium diamantinense and Stenandrium eustachyum, two new species from campos rupestres in a region of high endemism in southeastern Brazil. Stenandrium diamantinense is differentiated from other congeners by its unique indurate, small leaves with revolute margins. Stenandrium eustachyum is most similar to Stenandrium villosum, the only congener with which it shares the combination of oval bracts and caulescent habit; it can be distinguished from the latter species by its ovate to widely ovate leaves (vs. lanceolate in S. villosum). Stenandrium eustachyum differs from other species of Stenandrium from the Serra do Espinhaço by its oval (vs. linear in all other regional species) bracts. Photographs of living plants in the field are supplemented by scanning electron micrographs of pollen, seeds, and trichomes. A distribution map and a key to the Stenandrium species of the southern Serra do Espinhaço are provided. Stenandrium diamantinense is informally and provisionally assessed as Endangered and S. eustachyum as Critically Endangered. The distribution of Stenandrium in the Serra do Espinhaço supports proposed centers of endemism and key biodiversity areas.

Abstract—Lychnophorella comprises eleven species. It is characterized by the presence of a pad-like leaf sheath, strongly imbricate persistent phyllaries, glabrous corolla lobes, and apical anther appendages that are constricted at the base. The genus is restricted to the campos rupestres of Chapada Diamantina, Bahia State, Northeastern Brazil. Lychnophorella hindii is morphologically similar to L. santosii and Lychnophorella saxicola is similar to L. leucodendron. These new species are described and illustrated, their affinities discussed and an updated key for the genus is provided.

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.
