BOUVARDIA PASCUALII SPEC. NOVA (SECT. GYMNOSIPHON, RUBIACEAE) EN OAXACA, MEXICO

摘要

A new species of the genus Bouvardia belonging to the subgen. Bouvardiastrum, sect. Gymnosiphon was collected by Jose Pascual in the southern part of the state Oaxaca in Mexico. At first glance it is similar to the polymorphic B. multiflora (Cav.) Schult, et Schult, f. widely distributed in Mexico to El Salvador, but differs from it basically in having leaves with 3-5 veins, white flower and corolla tube glabrous on both sides.
