PEA FAMILY. Fabaccae. 



There are several kinds of Thermopsis, of North America 

 and Asia; stout, perennial herbs, with woody rootstocks; 

 leaflets three; stipules conspicuous, leaf -like; flowers large, 

 yellow, with short, bracted flower-stalks; calyx bell-shaped, 

 five-cleft; standard broad, in the western species, shorter 

 than the oblong wings, keel nearly straight, blunt, the 

 same length as the wings; stamens ten, separate, curving 

 in; style slightly curving in, stigma small; pod flat, long or 

 oblong, straight or curved, with a very short stalk and 

 several seeds. Thermopsis, sometimes called False Lupine, 

 is distinguished from Lupinus by its stamens, which are 

 separate, instead of united into a sheath. The Greek 

 name means "lupine-like." 



A very handsome, thrifty-looking plant, 



Golden Pea about t f fc h{ h th smooth bright 



Buck-bean 

 Thermdpsis green foliage contrasting finely with the 



montdna clusters of clear yellow flowers, each about 



Yellow three-quarters of an inch long. The erect, 



Spring, summer stra i g h t pO( j s two or three inches long, 

 Northwest, Utah, , , , 



Ariz are silky and also the calyxes and buds. 



This thrives in the mountains, up to an 

 altitude of nine thousand feet, in somewhat moist spots, 

 and its fresh coloring is most attractive. The foliage seems 

 to me to be especially handsome in northern Arizona, but 

 these plants are also beautiful in the Utah canyons. The 

 flowers are scentless and last a long time in water. T. 

 Californica has silvery, silky foliage and is common in 

 California, in damp ground in the hills. 



There are many kinds of Parosela, of western North 

 America, Mexico, and the Andes, no one sort common; 

 generally shrubs; leaves almost always compound ; leaflets 

 odd in number, small, toothless, with minute stipules, 

 often with glandular dots; flowers small, in terminal clus- 

 ters; calyx with nearly equal, long, occasionally feathery 

 teeth ; corolla with wings and keel longer than the standard, 

 their claws adhering to the lower part of the stamen-tube, 

 but the claw of the small, heart-shaped standard free; 

 stamens nine or ten, filaments united, anthers alike; ovary 

 with a short stalk, or none, style awl-shaped; pod small, 

 membranous, included in the calyx, usually with one seed. 

 P. spinbsa, the Smoke Tree, or Ghost Tree, of western 

 Arizona, is almost leafless, with grayish or whitish branches
