Agave neglecta continues to live up to its name, being known only from a series of photographs and incomplete, sterile herbarium specimens. Therefore, the above measurements are only an approximation, and all are subject to modification if and when fresh, reproductive material can be studied. Attempts to see this rare species in the field have been thwarted by development and hurricanes. H. S. Gentry (1982) suggested that it might be related to A. weberi, a freely suckering species that produces fiber of an excellent quality. Nothing is known about the uses of A. neglecta. The plant may well be a cultivar of A. sisalana or A. kewensis and represent an ancient introduction from Mexico.
