Agave involuta is a species of the agave genus( agave ) in the subfamily of the agave family (Agavoideae). The specific epithet involuta comes from Latin , means 'rolled up' and refers to the rolled up leaves of the species.

description

Agave involuta is 85 to 140 centimeters tall. The up to ten or more linear leaves are narrowly folded lengthways and often appear tubular. The leaf blade is 30 to 50 inches long and 0.2 to 0.5 inches wide. The leaf margins and the leaf veins on the underside of the leaf are - sometimes only indistinctly - papilous .

The inflorescence is "eared". The flower-bearing part is 10 to 20 centimeters long and has three to seven sessile flowers that are ascending when fully grown. The ellipsoid ovary is 6 to 9 millimeters long. The greenish, purple tinged tepals are dry Glauk -grünlichpurpurfarben. The narrow, funnel-shaped, 7 to 13 millimeter long flower tube is slender cylindrical towards its base, but not constricted. Their extended-ascending or slightly bent back tips are 8 to 10 millimeters long and usually shorter than the flower tube. The stamens are obviously more or less purple in color. They protrude over the flower tube by about 20 millimeters. The stylus is longer than the stamens . The flowering period extends from March to April.

Nothing is known about the fruits and seeds .
