A new haplostemonous species of Graptopetalum (subg. Glassia, Crassulaceae) from the Sierra de Coalcomán, Michoacán, is described and illustrated. It differs from its morphologically closest species, G. pentandrum, by having a smaller rosette diameter, broadly oblong leaves, its basal inflorescence branch with fewer flowers than in the rest of branches, a smaller flower diameter, wider petals, and its petal color pattern. It was assessed as Critically Endangered (CR) following the IUCN criteria. A key to the haplostemonous species of Graptopetalum (subg. Glassia) is provided.
Graptopetalum trujilloi (subg. Glassia, Crassulaceae), a new haplostemonous species from San Gabriel municipality, Jalisco, Mexico is described and illustrated. Its morphologically closest species is G. rosanevadoense. It differs from the latter in having a smaller habit, more numerous primary branches per inflorescence, larger mean flower density per 10 cm of the scape, fewer flowers per basal branch, smaller flower diameter, petals greenish with transversal inconspicuous red stripes, narrower petals, filaments greenish to distally reddish and carpels abaxially obtuse. A key to the haplostemonous species of Graptopetalum is provided and, according to IUCN criteria, the species was assessed as critically endangered (CR).
We describe and illustrate Agave infiernilloensis, a new species of the section Choritepalae (Agavoideae, Asparagaceae). It is morphologically similar to A. gypsicola from which it differs by having larger rosettes and leaves, shorter terminal spine, shorter and recurving inflorescence, more flowers per node, as well as longer flowers, ovary, and filaments. We assessed the species as Endangered (EN) according to the IUCN criteria. We provide a distribution map and a key to the choritepalous species of Agave.
A revision of Echeveria pringlei var. parva was made based on morphological and biogeographical comparisons. The results show that this taxon should be raised to the species level and that it belongs to E. ser. Nudae. Since the epithet parva is unavailable for use due to the existence of E. parva, E. flammigera is proposed as a new replacement name. An updated description of the taxon is provided, as well as a distribution map.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
