ESTUDIOS SOBRE RUBIACEAS MEXICANAS XLV Bouvardia juarezana (Rubiaceae, Spermacoceae) una nueva especie en Oaxaca

摘要

A new species named as Bouvardia juarezana (Spermacoceae tribe) was collected in the State Oaxaca (South Mexico) at the foothills of the Sierra de Juarez near Oaxaca city. It belongs to the relation of B. erecta, a xeromorphic shrubby plant of the dryareas of Central Mexico, spreading from Puebla y Tlaxcala to Oaxaca, where it is represented by several closely related taxa, like B. candidissima Borhidi, E. Martinez et Salas-Morales 2011 and B. mitlensis Borhidi et Salas-Morales 2010. The differencebetween these species is in the shape and indumentum of the small leaves, the inflorescences and mainly in the hairiness of the corolla tube inside, which is an important distinctive feature in several species groups of the genus.
