Baja California, abundant in the mountains at 300 to 1,800 meters. Cali- 

 fornia ; type from Monterey Bay. 



Shrub, 0.5 to 6 meters high, the branches brown or gray ; leaves 4 to 10 mm. 

 long, acute or obtuse, lustrous; petals about 1.5 mm. long. " Chamiso " (Baja 

 California). 



2. Adenostoma sparsifolium Torr. in Emory, Notes Mil. Reconn. 140. 1848. 

 Baja California, on mountain slopes at 1,000 to 1,750 meters. California ; 



type from Warner Pass. 



Shrub or tree, 1 to 10 meters high, forming dense thickets, the branchlets 

 green, the bark of old branches reddish brown, often peeling in thin sheets; 

 leaves 5 to 12 mm. long, gland-dotted ; flowers sometimes pinkish. " Palo 

 amarillo " (Baja California); " hierba del pasnio," "chamiso" (California). 



Often known in California as " greasewood." A decoction of the plant is used 

 locally for chills and fevers and as a tonic. The Coahuilla Indians of Cali- 

 fornia employed the wood for arrow points and rabbit sticks ; a decoction of 

 the twigs as a purgative and vomitive in the case of pains in the stomach and 

 intestines ; the powdered twigs mixed with grease as a salve ; and a decoction 

 of the plant as a remedy for sick cattle. 



7. FALLUGIA Endl. Gen. PI. 1246. 1840. 

 1. Fallugia paradoxa (D. Don) Endl.; Torr. in Emory, Notes Mil. Reconn. 140. 

 1848. 



Sieversia paradoxa D. Don, Trans. Linn. Soc. Bot. 14: 576. 1825. 



Geum cercocarpoides DC. ; Seringe in DC. Prodr. 2: 554. 1825.

Shrub, 1 to 2 meters high, the bark whitish, shredded ; leaves 1 to 2 cm. long, 

 divided into 3 to 7 linear revolute lobes ; flowers white, usually solitary, long- 

 pedunculate, the 5 petals 1.5 to 2 cm. long ; stamens numerous ; achenes with 

 feathery purplish tails 3 to 5 cm. long. " Ponil " (New Mexico). 



A very handsome shrub when in either flower or fruit ; of some value as a 

 forage plant. It is sometimes known in the southwestern United States as 

 "Apache-plume." The Tewa Indians of New Mexico employed the smaller 

 branches, tied in bundles, as brooms, and the larger ones for arrow shafts. 

 They also, like the Hopi of Arizona, employed an infusion of the leaves for 

 washing the hair to promote its growth, probably, according to Hough, because 

 of the hairy fruit.
