Perennial herbs. with creeping caudex, alternate leaves with 
dilated stipule-like base and corymbose cymes of white flowers.

round-reniform, deeply 5-7-lobed, the lobes irregularly toothed and cut, 
2-8 inches in diameter, the lower on long slender petioles with merely en- 
larged base, the upper similar but smaller,on shorter petioles with foliaceous 
stipular base: flowers many, in a corymbose at length elongated cyme; 
calyx campanulate, the lower half of the tube coherent with the ovary, 
enlarging and becoming erceolate in fruit; petals white, rounded above, a 
little longer than the triangular acute erect calyx-lobes: carpels united to 
above the middle, erect, the tips of the beaks divergent in fruit. In 
mountain streams, Oregon and California.

panulate, adherent to the lower half of the ovarv, enlarging and becomin 
urceolate in fruit; petals white, early deciduous, spatulate, narrowe 
below toa long claw, 2-3 lines Jong. much longer than the acuminate
