Salvia penghuana (Lamiaceae), a new species from Guizhou, China

Abstract

Salvia penghuana, a new species from Guizhou Province of southwestern China, is described and illustrated. Morphologically, Salvia penghuana is similar to S. filicifolia, but can be easily distinguished from the latter by ovate-lanceolate bracts, purple corolla, and foot-shaped fused lower arms of connective. In addition, S. penhuana is morphologically similar to S. cavaleriei, but differs by having 3–4-pinnate leave, ovate-lanceolate bracts, puberulent calyx, and longer upper arms of connective. Based on the fibril root, small calyx and corolla, and completely reduced posterior thecae, S. penghuana should be placed in section Sobiso of subg. Glutinaria.
