27th Mexican studies on Rubiaceae. A brief review and four new species of the genus Deppea (Hamelieae) [Estudios sobre Rubiáceas Mexicanas XXVII. Una revisión breve y cuatro especies nuevas del género Deppea (Hamelieae)]

摘要

The monographic treatment of the genus Deppea Schltdl. et Cham. published in 1988 by Lorence and Dwyer turned to be a broad sense approach with 23 species, including several alien elements and forming a polyphyletic unit. It was criticised by Borhidi et al. (2004) excluding 6 species belonging to 5 different genera. Since that time a number of real Deppea species of original sense has been discovered and described. Actually, the genus comprises 31 species without the excluded ones. In this volume 6 new species, in this paper 4 new ones: D. foliosa, D. nitida, D. rubrinervis, D. tubaeana and a new combination, D. arachnipoda are published, followed by a rectified generic description and a new analytic key.
