Systematics and distribution

Agave apedicellata is common in the Mexican state of San Luis Potosí at altitudes of 2450 meters.

The first description as Bravoa sessiliflora by William Botting Hemsley was published in 1880. Joachim Thiede and Urs Eggli placed the species in the genus Agave in 1999 . They had to choose a new name because the species Agave sessiliflora Hemsl was already there . (1880) existed. The species belongs to the subgenus Manfreda and is assigned to the Polianthes group there. A nomenclatory synonym is Polianthes sessiliflora (Hemsl.) Rose (1903) .

Agave apedicellata is not well known. It was collected in 1878 by Charles Christopher Parry and Edward Palmer (1831-1911) and is only known from this collection so far.
