A New Species, Habranthus sanavirone (Amaryllidaceae), from Argentina

A new species of Habranthus Herbert (Amaryllidaceae) is described and illustrated. Habranthus sanavirone Roitman, J. A. Castillo, G. Tourn & Uria is found in sandy soils of central Argentina. The new species resembles H. robustus Herbert in size but can be easily distinguished by the absence of bulblets, its glaucous leaves, and its recurved light yellow tepals, with this feature not found in any other species of the genus.
