The yellow-green, variable, linear to triangular upwardly directed, curved leaves are 15 to 25 cm long and up to 14 mm wide. Near the gray to brown terminal spine there are white, hairy tufts / tufts with a diameter of up to 15 mm.
The panicle inflorescence is 70 to 120 cm high. The bell-shaped purple flowers are 20 to 25 mm long and 8 to 10 mm wide.

Systematics and distribution
Agave albopilosa is common in Mexico, Sierra Madre Oriental in Huesteca Canyon in exposed places on steep limestone cliffs at an altitude of 1000 to 1500 m. It is associated with Agave bracteosa , Agave lechuguilla , Agave striata , Agave victoriae-reginae , Dasylirion berlandieri , Hesperaloe funifera , Hechtia texensis and other species.
The first description by Ismael Cabral Cordero , José Angel Villareal Quintanilla and Alejandro Eduardo Estrada-Castillón was published in 2007.
Agave albopilosa is a member of the Striatae group and is endemic to Huesteca Canyon in Mexico. The plants were discovered at the end of the last century and described in 2007. The white, hairy tufts / tufts near the terminal mandrel are unique. Characteristic are the individually growing or compact, small, dense groups with the yellow-green, variable, upward-pointing, curved leaves that are pressed against the steep rock walls. It is closely related to Agave striata , but differences in flower and fruit structure are recognizable. The accessible plants are severely decimated, but the plants growing on the steep walls of the cliffs are currently safe.
