The genus Abronia (Nyctaginaceae) in Colorado, with notes on Abronia Bolackii in New Mexico

摘要

Several taxonomic observations on the genus Abronia in Colorado and New Mexico are presented. First, Abronia argillosa Welsh & Goodrich is a synonym of A. glabrifolia Standl. Second, Abronia carletonii Coult. & Fisher is a synonym of A. fragrans NULL. ex Hook., and specimens of A. carletonii from New Mexico and Texas should be called A. nealleyi Standl. Third, Abronia elliptica is a species distinct from A. fragrans, as noted by several fruit and habit characteristics. Lastly, recognition of the newly described A. bolackii appears unwarranted and should be included in synonymy under A. elliptica. A distribution map of Abronia in Colorado is presented as well as photographs of fruits of each species.
