7. P. parryi Hel. Parry Dalea. (Fig. 

 205.) Stems slender, diffusely spreading, 1 to 

 2 feet long; herbage puberulent or glabrate; 

 leaflets 6 to 10 pairs, obovate or oblong, emarginate or obtuse, % to 2^/2 lines long, 

 with distinct petiolules; flowers 3 to 4 lines long, purple, in loose spikes; calyx tur- 

 binate, strongly ribbed, somewhat silky-canescent, its teeth ovate, acute, equaling 

 or shorter than tube; banner % and wings % as long as keel; banner cordately 

 renif orm and with a short sharp point at apex, the larger center whitish and with 

 translucent gland-dots, the purple sides turned in so as almost to make a sac; 

 wings and keel purple lengthwise on upper half, white on lower half; ovules 2; 

 "pod smooth." 



Arid gravel benches, washes and rocky slopes, 300 to 2000 feet : easterly part 

 of the mountain region lying between the Mohave Desert and the Colorado Desert. 

 Arizona to Lower California. Dec-June. 



Color note. — The flower is curiously color marked. The banner, so very small, is white with 

 inturned purple edges. The lower half of the keel and wings lengthwise are white, the upper 

 half purple. The effect, therefore, is as if the corolla were marked lengthwise of the middle by 

 a band of indigo, the band carrying white either side of it.
