Discussion
Varieties 2 (1 in the flora).
The component of Horkelia clevelandii occurring in the Sierra San Pedro Mártir and most of the Sierra Juarez of northern Baja California, Mexico, is var. brevibracteata (Wiggins) Ertter & Reveal. It differs from var. clevelandii in tending to have a more compact and matted habit, shorter stems (1–3 dm), more numerous (11–16) pairs of smaller (4–8 mm) leaflets, shorter epicalyx bractlets (1.5–2 mm), and deeper hypanthia (2–2.5 mm).
