Discussion

Varieties 3 (1 in the flora).

Variety tripetala (Paul G. Wilson) Barneby occurs in south-central Mexico (Michoacán to Morelos) and has fewer stamens (5–7) than var. urceolata (7–10). Variety lucida (Rose ex Rydberg) Barneby occurs in Durango and lacks the epistemonous petals; the banner is the only petal.
