PEREZ-CALIX, Emmanuel. Sedum reptans (Crassulaceae) and three related taxa from central Mexico. Rev. Mex. Biodiv. [online]. 2007, vol.78, n.2, pp.281-289. ISSN 2007-8706.

Sedum reptans subsp. carinatifolium R.T. Clausen (Crassulaceae) is raised to specific rank, as S. carinatifolium (R.T. Clausen) E. Pérez-Calix, based on morphological differences in leaves, inflorescences and flowers observed in plants of this taxon and those of Sedum reptans R. T. Clausen. They also differ in their ecological preferences. Additionally, two new species are described and illustrated: S. jerzedowskii, known from the northeastern portion of Querétaro and S. glassii, from northeastern Guanajuato. Based on habit and leaf size, as well as the morphology and yellow color of their flowers, all of the taxa treated in this publication belong to the "parvum group" of Sedum.

Keywords : Crassulaceae; Sedum; parvum group.
