Agave schottii var. schottii occupies a range from southeastern Arizona to extreme southwestern New Mexico and south into Sonora, Mexico. It occurs in varied habitats, from low and high desert scrub to grassland to juniper and oak woodlands. Most populations are found on rocky slopes of isolated mountain ranges at elevations from 900 to 2000 meters.
Leaves are 25 to 40 cm long, 7 to 22 mm wide, narrowly linear, usually falcate, and yellowish green with conspicuous bud imprinting.
The spicate flower stalk is 1.6 to 2.5 meters tall and 624 mm in diameter. The light yellow flowers are 29 to 42 mm long, either single or in clusters of 2 or 3 and appear from May to July.
In Arizona, this variety hybridizes with Agave chrysantha, A. parryi var. parryi and A. deserti subsp. simplex.
Agave schottii var. treleasei is a narrow endemic found only in Pima and Cochise counties in southeastern Arizona. It occurs at elevations from 1100-2000 meters in high desert scrub, grassland and juniper and oak woodlands.
Leaves are 25 to 40 cm long, 12 to 25 mm wide, linear, deep green with no bud imprinting.
The flower stalk is 2 to 4 meters tall, 2.6 to 3.3 cm in diameter. It is subspicate to narrowly racemose-paniculate, the longer branchlets 27 to 40 mm long, the shorter ones 0.7 to 2.2 mm long. The deep yellow flowers are 35 to 50 mm long, usually 2 per cluster. Flowers appear from May to July.
