description

Agave nanchititlensis forms daughter rosettes that appear from the leaf axils of this year's leaf rosette . Its numerous semi-fleshy roots are spread out horizontally from the rhizome base . The slender rhizomes are 1.5 to 2 inches long. The four to nine upright, overhanging, linear, tightly fibred leaves are rounded and runny . The leaf blade , spotted on both sides, is 21 to 39 centimeters long and 0.4 to 0.8 centimeters wide. The brown or dark green spots are irregularly shaped. The leaf veins on both sides are covered with individual rows of papillae . The leaf margins have a maroon line. They are entire or, like the leaf veins, tiny papillate . The remnants of the leaf base are fibrous and 5.5 to 7 inches long.

The "eared" inflorescence reaches a height of 35 to 94 centimeters. The very open flower-bearing part is 11 to 22 centimeters long and has seven to ten blooming nodes. The seated flowers are horizontal when fully grown. The long ellipsoid ovary is 11 to 17 millimeters long. The upper parts of the green tepals are tinged with purple. The narrow, cylindrical flower tube is straight or slightly curved. It has a length of 25 to 30 millimeters and is 3 millimeters wide in the middle. The yellowish green tips on both sides are turned back and 6 to 11 millimeters long. The stylus protrudes from the flower tube and is 45 to 56 millimeters long. The club-shaped scars are deeply furrowed and fully expanded. The flowering time is January.

The ellipsoid fruits are 1.5 to 1.9 inches long and 1.1 to 1.2 inches wide. They contain crescent-shaped seeds 3 millimeters in size.
