Yucca baileyi Wooton & Standley var. intermedia (McKelvey) Reveal
(Bailey's Yucca)


Family: Agavaceae

Status: Endemic

Synonyms:
Yucca intermedia McKelvey

Yucca baileyi var. intermedia reaches the southwest most extent of its range in the Gila/Apache National Forest. It is not the Yucca baileyi var. baileyi seen more to the north which is quite a bit more diminutive. Rather, it is the Yucca commonly seen in the central portion of New Mexico including the Albuquerque, Bernalillo and Santa Rosa areas. The leaves of Yucca baileyi var. intermedia are about 5mm wide and have frequent filaments coming from the whitish edges. Yucca baileyi var. intermedia is acaulescent (no stem) and the flower stalk bears flowers from below the level of the leaves. We use the nomenclature of Allred here for consistency-- FNA uses Yucca intermedia McKelvey.
