SYNOPSIS OF THE SPECIES 
ee *Ovules 2; pod included 
| Flowers spicate; herbs 
1. PAROSELA MOLLIS (Benth.) Heller, Cat. N. Am. PI. ed. 2. 
6. 1900.—Dalea mollis Benth. Pl. Hartw. 306. 1848.—Herbaceous 
from a perpendicular root, the spreading stems 5-15 cm. long, dotted 
with small, flat, brown glands, soft-villous, as are the leaves: 
leaflets 9-13, oblong, cuneate-oblong, obovate, or obcordate, usually 
retuse, 3-8 mm. long, dotted with a row of small marginal glands: 
flowers numerous in oblong spikes, 1-6 cm. long; calyx 6 mm. long, 
its teeth filiform from a triangular base, equaling or exceeding the 
glandular-dotted tube; corolla rose-tinted, not exceeding the calyx 
teeth; banner 2 mm., wings and keel 3 mm. long, the latter mostly 
with a small gland at base: pod obovate, hirsute, and glandless, 
3 mm. long: seed brown, reniform, 2 mm. long.—Fig. 1. 
Probably a short-lived perennial, sometimes flowering the first year. The 
flowers are on very short pedicels, bracteolate at base by a pair of swollen 
pointed glands, which persist on the rachis after the fall of the fruiting calyces. 
Type.—‘In vicinibus Monterey”; certainly an error. According to 
Warson, in the Botany of California, it was first collected by CouLTER, prob- 
ably in southern Arizona. 
DISTRIBUTION.—A common species in sandy and gravelly soils through- 
out the Lower Sonoran of the Colorado and Mojave deserts; thence northeast 
to southern Nevada (GooppING 2237), southeast through Arizona (THORNBER)
