Agave vazquezgarciae (Agavaceae), a New Species from Jalisco, Mexico

Abstract

Agave vazquezgarciae Cházaro & J. A. Lomelí, a new species from the Sierra de Manantlán Biosphere Reserve, Sierra de Cacoma, and Sierra de Cuale in southern Jalisco, Mexico, is described and illustrated. It belongs to subgenus Littaea (Tagliabue) Baker, group Amolae, and appears to be closely related to A. pedunculifera Trelease, which also occurs in western Mexico, including Jalisco. It differs from the latter in having a taller spike, much larger flowers, and firm, fibrous leaves that are narrower and have a larger, stouter terminal spine.
