Abstract

ROMERO-HERNANDEZ, Carolina. Synopsis of the species of the genus Abarema (Leguminosae: Caesalpinioideae) growing in Colombia. Rev. acad. colomb. cienc. exact. fis. nat. [online]. 2019, vol.43, n.169, pp.705-727. ISSN 0370-3908.  https://doi.org/10.18257/raccefyn.793.

A synopsis of the species of the genus Abarema (Leguminosae) growing in Colombia is presented. Sixteen species are recognized, including five varieties, three endemic species (A. callejasii Barneby & Grimes, A. josephi Barneby & Grimes and A. lehmannii (Britton & Rose ex Britton & Killip) Barneby & Grimes) for the country and two new records for the Colombian flora (A. acreana (J.F. Macbr.) L. Rico and A. racemiflora (Donn. Sm.) Barneby & Grimes). Two dichotomous keys are provided for the identification of the species: One for specimens with the presence of flower and/or fruit, and another that uses strictly vegetative characters. A brief discussion is included for each taxon highlighting its diagnostic morphological characters, notes on their geographical and altitudinal distribution, flowering and fruiting times, common names and uses, as well as a list of the herbarium specimens studied. In Colombia, the species of Abarema are predominantly found in humid and rain forests, mainly in the Andean and Amazonian regions.
