Agave aurea is a plant from the genus of the Agave ( agave ). An English common name is "Baja California Sur Century Agave".
description
Agave aurea forms short stems with open rosettes. Individual rosettes reach heights of 100 to 120 cm and a diameter of 150 to 200 cm. The variable, linear to lanceolate, curved, fleshy, runny, green to bluish leaves are 63 to 110 cm long and 7 to 12 cm wide. The leaf margins are serrated. The flexibly arranged, dark brown to gray terminal mandrel is 2.5 to 3.5 cm long.
The paniculate, massive, straight to curved inflorescence is 2.5 to 5 m high. The bell-shaped, yellow flowers are 43 to 70 mm long and appear from the middle of the inflorescence and reach the tip, on loose, long, irregularly arranged branches. The flower tube is 8 to 14 mm long.
The variably shaped brown, three-chamber capsule fruits are 45 to 17 mm long and 35 to 15 mm wide. The moon-shaped, black seeds are 7 to 8 mm long and 5 to 5.5 mm wide.
The flowering period extends from February to May.
Systematics and distribution
Agave aurea grows in Mexico in the state of Baja California Sur on lava slopes at an altitude of 300 to 1070 m. It is associated with cacti and succulent species.
The first description by Townshend Stith Brandegee was published in 1889. A synonym is Agave campaniflora Trel.
Agave aurea is a member of the Campaniflorae group . The species forms massive colonies on the western slopes of the Sierra de la Gigantea. The flower structure is similar to the other members of the Campaniflorae group. The long, narrow, lanceolate, green, curved leaves are typical. It is closely related to Agave capensis and Agave promontorii , but differs significantly in size, shape, leaf and flower structure.
