Abstract
-
Systematic studies on Erisma, one of the seven genera of the tropical family Vochysiaceae, are provided in this monograph. Erisma is distinguished from the other genera of the family by the inferior and unilocular ovary, the deciduous spurred-sepal, and the samaroid, four-winged fruits.;The 16 species of Erisma are tall trees predominantly in terra firme forests of the Amazon region, most of them with a limited distribution. Erisma uncinatum is the most common and widely distributed species of the genus with a range that follows the limits of Amazonia. Erisma arietinum, which is described as a new species from coastal forests of eastern Brazil, represents the first record of the genus outside Amazonia.;A key to the tribes and genera of Vochysiaceae is provided. A key to the species of Erisma, synonymy, descriptions, distribution, habitat, local names, uses, and specimens examined are presented. An overview of morphology and anatomy is provided and patterns of distribution, ecology, and phylogenetic relationships among the genera of Vochysiaceae and species of Erisma are discussed.;Erisma contains some of the most specialized members in the family. Erisma calcaratum, the only species in the genus found in inundated forests and with wingless fruits adapted for dispersal by water, is probably the most specialized member of the genus.
