Agave filifera subsp. multifilifera grows singly and forms short stems. The rosettes are 100 to 150 cm wide. The light green, linear to lanceolate, variably arranged leaves are 50 to 80 cm long and 1.2 to 3.5 cm wide. The leaf margins are densely fibrous. The gray to brown terminal mandrel is up to 1.3 cm long.
The annual inflorescence is up to 5 m high. The green to pink colored, numerous flowers are 40 to 45 mm long, appear between the leaves and line up to the tip of the inflorescence on the variably arranged branches. The flower tube is up to 5 mm long.
The elongated to egg-shaped, three-chambered capsule fruits are 20 to 25 mm long and 10 to 12 mm wide. The black, variably shaped seeds are 3.5 to 4.5 mm long and 2.5 to 3 mm wide.

Systematics and distribution
Agave filifera subsp. multifilifera grows in Mexico in the states of Chihuahua , Durango and Sinaloa in mountainous regions from 1400 to 2200 m altitude. It is associated with numerous types of succulents and cacti.
The first description by Howard Scott Gentry was published in 1972. On the basis of literature studies, the species from Ullrich was divided into the subspecies Agave filifera subsp. multifilifera reduced. The systematic position needs further investigation.
Agave filifera subsp. multifilifera is a member of the Filiferae group . The distribution area ranges from Central Chihuahua to North Durango to North Sinola. The species is one of the most robust representatives within the group. In the youth stage they resemble Agave filifera , but the differences in size and leaf structure are recognizable. It is closely related to Agave schidigera , but differences in leaf and flower structure become clear.
