Senecio chipauquilensis (Asteraceae, Senecioneae), a new species from the Meseta de Somuncurá (Patagonia), Argentina

摘要

A new species, Senecio chipauquilensis, from the Meseta de Somuncurá in the province of Rio Negro (Argentina), is described and illustrated. The new species resembles Senecio subpanduratus, but it is clearly different by its sessile basal leaves, strongly auricu-late and amplexicaul cauline leaves, and less number of phyllaries in the head, dor-sally 1-2 veined.
