Subspecies, varieties, forms and cultivars of plants belonging to the Agave parry group

Agave parryi is widespread over a vast territory giving rise to a corresponding amount of variability. This variability has been recognized by botanists and the current thinking by agave taxonomists is that Agave parryi consists of two subspecies: Agave parryi ssp. neomexicana and A. parryi ssp. parryi. The ssp. parryi is further divided into four varieties; the nominate form, var. couesii, var. huachucensis and var. truncata. The distinctions between the varieties are somewhat ambiguous and, although the varieties are weakly differentiated, it appears that there is some geographic separation between them.

  • Agave parryi Engelm.: (subsp. parryi var. parryi) Rosettes globose compactly imbricate, leaves broadly oblong, one-third to two-fifths as wide as long, 10 to 15 cm broad, 30 to 40 cm long, scape 4–6 m tall; perianth tube 6–12 mm, limb lobes 4–6(–7) mm wide; capsules 35-50 mm broad. Distribution: Central and southeastern Arizona.
  • Agave parryi var. couesiiAgave parryi var. couesii (Engelm. ex Trel.) Kearney & Peebles: it is a somewhat smaller plant with leaves less closely imbricate and smaller flowers 25 to 50 mm long. Distribution: Yavapai and Gila Counties from the north-western border of the species' range.
  • Agave parryi var. huachucensis (Baker) Little in L.D.Benson: is more robust, the leaves larger up to 35 cm wide and up to 65 cm long, and the panicle broader with larger flowers up to 75 mm long. Distribution: endemic of the Huachuca Mountains.
  • Agave parryi subs. neomexicana (Wooton & Standl.) B.Ullrich: has leaves that "tend to be some-what more narrow, rosettes flat-topped, scape shorter, 3–4,5 m tall with fewer branches. Distribution: New mexico.
  • Agave parryi var. truncata Gentry: it is distinguished by its very small leaves with acute to truncate apex, shorter marginal spines and doesn't sucker much if at all.
  •  Agave parry RUBYAgave parryi cv. Ruby: The leaves in full sun take a nice purple tinge (hence the name).
