Scanned 18 May 2015.

Coll. No. 225, 27 Apr 2000, characters observed: Herbaceous perennial, woody at base, erect, to 20 cm., not gland-dotted; Leaves, compound, leaflets 3-4, subpalmate (axis apparent beyond lower-most leaflet), main axis extending as a leaflet, leaflets, ovate, 7 mm. × 3 mm. wide, length 2.3 × width, entire, flat, stipules, gland-like, black; Inflorescence, 1-2 flowered, peduncle (5)6-10 mm.; Flower bilateral; Corolla 10 mm.; Calyx, tube 3 mm. + lobes 2-3 mm. = 5-6 mm., tube ≥ lobes; Fruit, 9 mm., flat, curved 90°, beak, 2 mm., straight.

The various combinations of short peduncles, strigose caylx lobes, and curved fruit do not fit any of the taxa known to the eastern Mojave Desert very well. Therefore, A. ridigus is a compromise.
