each head about Yi in. across and terminating the white- 

 woolly branch of a simple umbel. Fruit flattened, ribbed at

 wet ground from Wawona and Yosemite to timber-line. 



6. ANGELICA. 



1. A. lineariloba Gray. Stems stout, clustered, 2 to 6 ft. 

 high, from a perennial base, the whole herbage glabrous. 

 Leaves twice compound; leaflets numerous, linear, 1 to 4 in. 

 long, entire, or the lower parted into 3 linear lobes. Flowers 

 white, in loose compound umbels destitute of bracts. Fruit 

 oblong, glabrous, nearly j/2 in. long, with winged margins and 

 intermediate ribs, the oil-tubes conspicuous. — A rare plant, 

 first described from specimens gathered at Ostrander's 

 Meadows. A. breweri Gray, our only other Angelica, has 

 much wider (lanceolate) leaflets, which are regularly toothed 

 and commonly pubescent. It grows at Hetch Hetchy, Chil- 

 nualna Falls, etc. 



Ligusticum grayi C. & R., resembles a species of Angelica, 

 but its fruit is flattened from the sides instead of from the 

 back and front; the stems are tall and the large leaves 

 (chiefly basal) have many cut-toothed leaflets. Its type 

 locality is Ostrander's Meadows.

 and with intermediate ribs. — Common in moist places of mod- 

 erate altitude.
