Abstract
Two new species are described and illustrated. Echeveria cuevasii shares with E. flammigera typical characteristics of Echeveria of the Nudae series, for instance, a subshruby habit, medium-sized rosettes and short sub spicate inflorescences. However, it differs from the latter by having fewer shorter branches, longer leaves, more flowers per inflorescence, longer bracts; shorter stamens and petals with bright yellow margins. Echeveria vazquezii is similar to E. marianae and E. novogaliciana by having large and glabrous rosettes, short caudex, and paniculate inflorescence with several cincinni, typical features of Echeveria series Gibbiflorae, in addition to the presence of appendages on the inner side of the petals. However, it differs from both species by the deciduous bracts, fewer cincinni per inflorescence, and whitish to pale yellow nectaries. A classification of the risk status of the two species proposed as new is provided.
