In order to investigate biogeographic influences on xeric biota in the Brazilian Atlantic Forest (BAF), a biodiversity hotspot, we used a monophyletic group including three cactus taxa as a model to perform a phylogeographic study: Cereus fernambucensis subsp. fernambucensis, C. fernambucensis subsp. sericifer, and C. insularis. These cacti are all...

Cereus (Cactaceae; Cereeae) comprises c. 30 predominantly South American species distributed among the subgenera Oblongicarpi, Ebneria, Mirabella and Cereus. To study patterns of diversification in time and space, the trnS-trnG plastid region was sequenced from representatives of Cereus and the closely related genera Cipocereus and Praecereus. For...

Discocactus petr-halfarii was previously regarded as synonym or subspecies of D. bahiensis. On the basis of field surveys and literature analyses, taxonomic investigations and phylogenetic studies, this species is placed as a subspecies of D. zehntneri. New synonymy is also established for D. heptacanthus.

Summary: Rhipsalis flagelliformis, sp. nov., is described from Rio de Janeiro state, where it is narrowly endemic. It superficially resembles the Mexican Disocactus flagelliformis and cannot be confused with any other Rhipsalis species. In habit the plant appears to be highly neotenic, retaining the seedling characters typical of some members of it...

The genus Haageocereus (Cactaceae) is almost endemic to Peru, occupying arid areas of river valleys draining westwards off the Andes. Extensive fieldwork, morphological studies, literature revision and a study of the types led to the delimitation of 9 species and 6 heterotypic sub-species. Nomenclatural innovations include H. acranthus subsp. backe...
Article
The invalidly published Monvillea kroenleinii Kiesling, recently described from the Chaco of western Paraguay, is validated as Cereus kroenleinii N. P. Taylor and its range significantly extended to include north-eastern Bolivia and western Brazil.
