While the first Agaves of Arizona installment featured naturally occurring Agaves definitively placed in one subgenus (Agave) or the other (Littaea), our second installment continues with a venture into the somewhat more tenuous realm of naturally occurring hybrids and anthropogenic (literally, man-made) cultivars, in other words, the fun stuff! A peek back at Part I in vol. 89-6 might lend a sense of continuity, as reference is made to several taxa previously discussed. Please note that range maps exclusively represent sites we have personally visited and documented.

A new species, Agave cremnophila, is described from Cerro las Flores in the state of Oaxaca, Mexico. It is a small-sized species in the group Striatae and is endemic to Oaxaca; the closest relatives, based on flower and leaf morphology, are Agave dasylirioides Jacobi & Bouché from the cliffs near Tepoztlán, Morelosl the recently described A. kavandivi A. J. García-Mendoza & C. Chávez-Rendón from Cerro Kava Ndivi in western Oaxaca, and A. stricta Salm-Dyck from southern Puebla and northern Oaxaca. The addition of Agave cremnophila brings to 10, the total number of species in the Striatae, all found in Mexico.
