90. BACCHARIS L. 

 Perennials, ours shrubs excepting one, commonly resinous or glutinous. 

 Heads many-flowered. Involucre imbricated. Flowers whitish or yellowish, 

 dioecious. Staminate flowers with tubular corolla slightly dilated at the throat, 

 the limb cleft into 5 linear lobes; ovary abortive; style present. Corolla of 

 the pistillate flowers very slender and thread-like, obscurely toothed at apex, 

 the teeth erect, not spreading. Pappus of capillary bristles in the sterile plant 

 scanty and tortuous; in the fertile very long and copious. (The god Bacchus.) 



Evergreen shrubs. 



Leaves obovate or cuneiform 1. B. pilnlaris. 



Leaves lanceolate, willow-like 2. B. viminea. 



Herbaceous perennial; herbage very glutinous 3. B. douglasii. 



1. B. pilularis DC. Chapparal Broom. Shrub, 2 to 5 ft. high; branchlets 

 angular; leaves sessile, obovate or cuneiform, % to 1 in. long, coarsely or 

 sinuately few-toothed, or occasionally entire; heads 2 or 3 in the axils or 

 several in a terminal cluster, short-cylindrical or ovoid, 2 or 3 lines long, the 

 outer bracts broadly, the inner narrowly oblong, sometimes denticulate at 

 apex; pappus of the pistillate flowers becoming 4 or 5 lines long, that of the 

 staminate flowers dilated at apex into a lanceolate appendage. 



Common on low hills, high mountain slopes, or on the coast sand dunes 

 (especially in a prostrate form), frequently gregarious: Coast Eanges south 

 to Southern California and north to Oregon. Also in the Sierra Nevada. 



2. B. viminea DC. Mule Fat. Distinctly shrubby, the stems loosely 

 branching, very leafy, 5 to 7 ft. high; branches striate-angled; herbage scarcely 

 glutinous; leaves lanceolate, acute at both ends, entire or sparingly denticulate, 

 1 to 3 in. long, very willow-like; heads 2 to 3 lines high, rather numerous in 

 terminal corymbs or the clusters on short lateral branches and somewhat race-
