description
Agave zebra grows individually. The open rosettes are spread out. The gray to bluish, lanceolate, deeply rutted, roughened leaves with the typical transverse bands are 50 to 80 cm long and 12 to 17 cm wide. The wavy leaf margins are serrated irregularly. The pointed, brown to gray terminal mandrel is 3.5 to 7.5 cm long.
The paniculate, straight to curved, narrow inflorescence is 6 to 8 m high. The yellow flowers are 50 to 70 mm long, appear on the upper part of the inflorescence and form on loosely arranged variable branches. The funnel-shaped flower tube is 6 to 7 mm long.
The elongated to egg-shaped brown three-chambered capsule fruits are 40 to 50 mm long and 12 to 15 mm wide. The black seeds are 4.5 to 5 mm long and 4 to 4.5 mm wide.
The flowering period extends from June to August.
Systematics and distribution
Agave zebra grows endemically in Mexico in the state of Sonora on stony limestone slopes at an altitude of 700 to 1000 m.
The first description by Gentry was published in 1972.
Agave zebra is a member of the Marmoratae group and grows in limited areas in Sirra del Viejo and Cerro Quituni in northern Sonora. Typical are the conspicuously cross-banded stripes on the leaves with the strong, curved, serrated leaf edges. Agave zebra is similar to Agave fortiflora , but there are differences in leaf and flower structure.
