description

Agave chamelensis reproduces vegetatively by buds from the rhizome below the leaf bases. The upright cylindrical rhizomes are 3 to 15 inches long and 2 to 3 inches wide. Their roots are fleshy. The up to nine spread, brittle and herbaceous to somewhat fleshy leaves are narrowly runny and slightly folded near the base. It has a narrow base and a pointed tip. The leaf veins are papillate on both sides . The leaf blade is 37 to 77 (rarely up to 91) centimeters long and 1.6 to 4.8 (rarely 1 to 6.5) centimeters wide. The tiny toothed leaf margins consist of a narrow, yellowish, cartilaginous band. The teeth are regular. The remains of the leaf bases are membranous and do not disintegrate into fibers.

The "eared" inflorescence reaches a height of 75 to 120 (rarely up to 200) centimeters. The flower-bearing part is 10 to 20 centimeters long and bears ten to 25 (rarely up to 35) sessile flowers that are almost upright when fully grown. The elongated ovoid to ovary is 5 to 10 millimeters long. The tepals are green. The funnel-shaped flower tube has a length of 6 to 13 millimeters. The elongated, turned back to tightly rolled back tips are 8 to 11 millimeters long. The stylus protrudes over the flower tube by 25 to 35 millimeters. The club-shaped scars are triangular. The flowering time is December.

The spherical fruits are 1.2 to 1.6 millimeters long and 1 to 1.5 millimeters wide. They contain somewhat wedge-shaped seeds 5 to 6 millimeters long and 4 to 5 millimeters wide.
