Plants acaulescent, freely suckering; rosettes cespitose, 6-12 × 8-14 dm, open. Leaves ascending, 50-80 × 6-10 cm; blade light glaucous green to yellow green, frequently lightly cross-zoned, spatulate, firm, adaxially concave toward apex, abaxially convex toward base; margins undulate, armed, teeth single, well defined, mostly 3-4 mm, ca. 1-2 cm apart; apical spine dark brown to grayish, conical, 1.2-2 cm. Scape 3-4 m. Inflorescences narrowly paniculate, prolifically bulbiferous; bracts persistent, triangular, 10-15 cm; lateral branches 10-16, slightly ascending, comprising distal 1/4 of inflorescence, longer than 10 cm. Flowers 12-21 per cluster, erect, (5.1-)6-7.5 cm; perianth cream, apex purplish or brownish, tube urceolate, 14-20 × (11-)14-19 mm, limb lobes erect, unequal, (14-)15-20 mm; stamens long-exserted; filaments inserted unequally at or slightly above mid perianth tube, erect, yellow, (3.3-)4.5-5 cm; anthers yellow, (16-)22-25 mm; ovary (1.8-)2.2-4 cm, neck slightly constricted, (0.5-)4-6 mm. Capsules short-pedicellate, obovate to oblong or ovate, 5-7 cm, apex short-beaked. Seeds (7-)9-11 mm. 2n = 60. Flowering late winter--spring. Near drainage systems in desert scrub; of conservation concern; 400--1000 m; Ariz.; nw Mexico. Agave murpheyi, used by the Hohokam for food, is known only from around pre-Columbian agricultural and settlement areas. The plants (including bulbils) are easily transported and transplanted. Agave murpheyi hybridizes with A. chrysantha in Arizona.
