description

Furcraea tuberosa grows without a trunk or forms a trunk up to 30 centimeters high. The up to 60 broad, elongated, lanceolate leaves are almost flat and moderately runny at both ends. Their bright green, smooth and somewhat leathery leaf blades are about 110 to 150 centimeters (rarely up to 180 centimeters) long and 10 to 15 centimeters (rarely up to 17 centimeters) wide. The sharp point is slightly runny and has an attached point 1 to 2 millimeters in length. The leaf margin is straight between the simple and recurved or paired marginal teeth. The falling brownish-red marginal teeth are 5 to 10 millimeters (rarely up to 13 millimeters) long and are 2 to 6 centimeters (rarely up to 12 centimeters) apart.

The spindle-shaped inflorescence reaches a height of 5 to 8 meters and bears abundant egg-shaped bulbils . The blooms , which stand together up to three, are 42 to 51 millimeters long (rarely 38 to 55 millimeters). They stand on 6 to 9 millimeter long flower stalks . Their elongated tepals are about 21 to 27 millimeters (rarely 18 to 30 millimeters) long and 6 to 9 millimeters wide. The inner tepals are slightly wider than the outer ones. The ovary has a length of 20 to 25 millimeters. The stylus becomes 15 to 25 millimeters long. The flowering period extends from December to March.

Fruits and seeds are unknown.
