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.


Phenology: Flowering late winter–spring.
Habitat: Near drainage systems in desert scrub
Elevation: 400–1000 m

Discussion

Of conservation concern.

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.
