PLANT: Annual 5-30 cm tall, erect, with several branches. LEAVES: subglabrous to sparsely villous and viscid, entire to pinnately lobed, with 1-3 pairs of lateral lobes, 1-5 cm long. CALYX: 5-7 mm long; corolla slightly zygomorphic, with 3 dorsal lobes and 2 ventral lobes, the tube and throat 6-14 mm long, often twice the length of the calyx, the lobes 4-8 mm long, the throat yellow, the lobes bright blue to bluish lavender; stamens inserted near the base of the throat, about equal to the length of the lobes, exserted and often bent upward; pistil 12-15 mm long; style included in the throat to slightly exserted. CAPSULE: 3-5 mm long. NOTES: Washes, bajadas, desert shrublands and woodlands: Cochise, Gila, Graham, La Paz, Maricopa, Mohave, Pinal, Yavapai, Yuma cos; 1000-4500 ft; Mar-Jun. s CA to sw UT, s to n MEX. This species includes subsp. yageri (M. E. Jones) H. L. Mason, with slightly zygomorphic, bright blue corollas. This is the common subspecies throughout much of AZ, but the differences from typical subsp. eremicum, which has more lightly colored, zygomorphic corollas, are apparently gradual over a broad geographical gradient extending into CA and s NV.
