Agave coetocapnia is a species of flowering plant in the family Asparagaceae, native to Mexico.

The flowering stem (scape) is about 30 cm (12 in) tall, and has small leaves which gradually turn into bracts within the inflorescence, which is a terminal raceme.

[3] The complex nomenclatural history of the species was discussed by Rafaël Govaerts and Joachim Thiede in 2013.

Govaerts and Thiede commented that this may be the only case where three botanists have independently chosen the same epithet in different genera for the same species.

Accordingly, in 1999, Joachim Thiede and Urs Eggli chose Agave duplicata as a replacement name.

Under the rules of the International Code of Nomenclature for algae, fungi, and plants, the earliest available epithet must be used.
