| 英文摘要 | Background and Aims: The genus Coutaportla is distributed from northern Mexico to Guatemala and Honduras. It is characterized by tetramerous or pentamerous flowers and loculicidal-dehiscent capsules. Its circumscription has been a matter of debate since the genus Lorencea was segregated. However, molecular studies and morphological characteristics do not support this separation, and therefore the genus includes five species. The objective of this work is to present an updated treatment of Coutaportla, , including recently described new species, identification keys, distribution maps by species, and taxonomic descriptions. Methods: A bibliographic review of taxonomic studies and protologues of Coutaportla was conducted. Herbarium specimens, including types, were examined, and online collections and specialized internet portals were consulted to update taxonomic information and generate distribution maps. Key results: Coutaportla includes five species, all of them found in Mexico, with four being endemic and one also distributed in Central America. Three of these are only known from the type locality within the country. Additionally, information about vegetation types where the species develop is presented, ranging from arid, temperate to tropical-humid. Morphologically, species recognition is based on ovary placentation (subapical, median, or basal), floral and leaf characteristics. Conclusions: The comprehensive morphological study of the Coutaportla genus supports the synonymy of Lorencea. . Furthermore, it highlights morphological differences and provides analyses of conservation status in which the importance of the genus as a subendemic element for Mexico with a restricted distribution of most of its species is highlighted. |
