Etymology: In reference to the persistent short brown hairs on the leaflets.

Historical notes:

Distinguishing features: Extremely coriaceous leaflets with persistent short hairs at maturity.

Distribution and habitat: Southeastern Veracruz, Mexico. Growing from sea level to 200 m in generally arid thorn scrub to sandy soils and in limestone sea cliffs.

Conservation status: Locally quite abundant and producing copious quantities of seed. Threatened only by habitat destruction except in cliffside populations which seem to be safe. 1997 IUCN Red List of Threatened Plants Category V,II,V.
