Low tufted annual 2-7 cm. high, or often with several prostrate branches up to 10 cm. long, 

 glabrate or commonly tomentulose. Leaves 1-2 cm. long, the upper cuneate with 3 larger apical 

 teeth and 1 or sometimes 2 pairs of lateral ones, abruptly narrowed into a winged petiole, the 

 teeth and margins of the petiole with slender whitish bristles, often in pairs, basal leaves narrowly 

 linear-subulate, little or not at all dilated at the apex ; flowers usually crowded in terminal brac- 

 teate clusters ; calyx about 6 mm. long ; corolla bluish lavender, not spotted, almost regular, 

 12-16 mm. long, the lobes oblong-oval, obtuse or acutish and entire at apex, about one-third as 

 long as tube ; stamens shorter than the corolla-lobes.

 of California from Inyo County to the southern boundary of the state, east to south Idaho, Utah, Nevada, and 

 Arizona, and south to Lower California and Sonora. Type locality: Big Canyon, mouth of Diamond River, north- 

 western Arizona. April-June.

 3-5-toothed apex, narrowed to a winged petiole bearing simple or 2-3-forked bristles on the 

 narrow margins, the lower linear or not at all broadened at apex, finely bristle-toothed through- 

 out ; calyx 8-9 mm. long; corolla 15-20 mm. long, lilac, nearly regular, the lobes entire and 

 obtuse at apex, purple-dotted and each with 2 low longitudinal channels ending at base in a low 

 yellowish lanate ridge ; anthers blue ; capsule narrowly oblong, 3-sided, the angles acute. 



Dry gravelly bajadas or mesas, Sonoran Zones; desert regions; White Mountains, Inyo County, south to

Langloisia Schottii Greene, Pittonia 3: 30. 1896. 



Low tufted annual 2-12 cm. high, main stem evident, erect and producing rather slender 

 lateral branches throughout, or often branched at the base into several stout prostrate spreading 

 branches, villous. Leaves linear to narrowly linear-oblanceolate, or the uppermost cuneately 

 dilated at apex, 1-2.5 cm. long, sessile, pectinately pinnatifid, the teeth bristle-tipped or some- 

 times almost entirely reduced to bristles ; calyx 3-4 mm. long, villous ; corolla pale lavender or 

 pink, rarely white or yellowish, 8-14 mm. long, upper lip 3-lobed with the lobes spreading and 

 purple-spotted or sometimes with a larger arch-shaped spot ; lower lip deeply 2-lobed, the lobes 

 divergent, usually spotted at the base, one-half to one-third the length of the tube, linear to 

 oblanceolate, acute ; stamens declined, as long or longer than the corolla-lobes ; capsule ovoid, 

 3-angled, 3^ mm. long, 2-6-seeded. 



Sandy washes and plains, Sonoran Zones; Mojave and Colorado Deserts, California, east to southern Utah and 

 Arizona, south to northern Lower California and Sonora. Type locality: "Colorado Desert, Sonora." March-June.

 Western Mojave Desert: Willow Springs, midway between Mojave and Cinco, one mile north of Ricardo, and 

 Box S Ranch. Type locality: Willow Springs, Kern County, California. This is a little-known form, for the 

 present probably best considered a variant of Langloisia Schottii.
