The flower tube is hardly enlarged. Your mouth is crooked. The 2.5 to 4 millimeter long tips are erect, ovoid and blunt. At the tips they are covered with a tuft of short white hair .

The (unripe) fruits are egg-shaped and have a diameter of 5 millimeters and more. Nothing is known about the seeds .

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. Agave confertiflora is hardly known.
