5-16 RANUNCULACEAE 



1. C. ligusticifolia Nutt. Yerba de Chivato. Nearly glabrous, except the 

 iiifloreseeiiee ; leaflets 5 to 7, ovate, cordate or obtuse at base, 3-lobed or coai-sely 

 toothed about midway, or nearly entire, mostly 1 to 3 inches long; peduncles 



1 to 4 inches long, bearing a panicle of many to numerous flowers ; flowers ^2 

 to % inch in diameter ; sepals narrowly oblong, acute, tomentulose ; tails of the 

 achenes 10 to 13 lines long ; fruiting panicles corymbose to long-paniculate, 2 to 

 15 inches long. 



Valleys, foothills and mountains: Coast Ranges; Sierra Nevada; Southern

Biol, ami Economic Note. — It climbs high over shrubs and sometimes ascends trees. In 

 Mill Creek Caiion, San Bernardino Mts., we found the vines festooning alders (Alnus rhombi- 

 folia Nutt.) to a height of .50 feet; their trunk "cables" or stringers measured 4 to 12 inches 

 in circumference. An infusion of the herbage is used by Spanish-Californians as a healing 

 wash for barbwire cuts in horses.
