The widespread Neotropical species Polygala glochidiata has traditionally been considered the only Polygala with uncinate seed hairs to occur in Mexico. A second species with such hairs is shown to occur partly sympatrically with P. glochidiata in Jalisco and Nayarit and is referred to P. minima, heretofore considered to be a species restricted to southern Brazil, Paraguay, and northern Argentina. A single collection from the state of Mexico is also referred to P. minima, while the situation from Oaxaca southeastward into Central America is more complex. Patterns of variation in the P. glochidiata complex require further study, but data are presented to dispute the synonymization of P. minima into P. glochidiata by Bernardi. |
