Systematics and distribution
Agave delamateri grows in central Arizona on stony open slopes and in open woodland at an altitude of 700 to 1600 m. It is associated with numerous types of succulents and cacti .
The first description by Wendy C. Hodgson and Liz Slauson was published in 1995.
Agave delamateri is a representative of the Ditepalae section . It is extremely rare; only a few small colonies grow in a geographically isolated area in central Arizona. The species makes abundant rhizomatous offshoots. It is related to the allopatric agave fortiflora and agave palmeri , but differences in size, shape, leaf and flower structure are recognizable. Agave delamateri hybridizes with Agave chrysantha . Agave delamateri is grown in the Desert Botanic Garden in Tucson , Arizona.
The species is considered a pre-Columbian food and fiber crop that originated in southern Mexico. Nevertheless, the plant occurs in connection with archaeological finds.
