description

Agave murpheyi is monocarpic. It forms compact rosettes that sprout abundantly. The growth height ranges from 60 to 80 cm with a diameter of up to 100 cm. The linear, variably arranged, light yellow-green to bluish, slightly cross-banded, pointed leaves are 50 to 65 cm long and 6 to 8 cm wide. It forms clear imprints of the bud. The wavy leaf margins are serrated. The dark brown end thorn is 1.2 to 2 cm long.

The paniculate inflorescence becomes 3 to 4 m high. The waxy, light green to purple colored flowers are 65 to 75 mm long and appear on the upper part of the inflorescence on variably arranged branches. It rarely produces seeds, but after flowering bulbils on the inflorescence. The cup-shaped flower tube is 16 to 20 mm long.

The egg-shaped to elongated three-chamber capsule fruits are up to 5 to 6 cm long and 2 to 2.5 cm wide.

The number of chromosomes is 2n = 60.

Systematics and distribution

Agave murpheyi is distributed in the southwest of the United States in Arizona and in Mexico in the state of Sonora in various soil formations on stony slopes in desert regions at an altitude of 450 to 950 m. It is associated with numerous succulent and cactus species.

The first description by Frederick Gibson was published in 1935.

Agave murpheyi is a representative of the Ditepalae section . It forms narrow rosettes with short, broad leaves and resembles Agave chrysantha when young . The species seems to be associated in part with the old homes of indigenous peoples. It hybridizes with agave chrysantha . Agave murpheyi is grown in the Huntington Botanic Garden in San Marino, California.
