in terminal compound panicles or cymes. Flowers perfect, ca- 
lyx 5-cleft, sometimes only 3- or 4-cleft, persistent. Disk obso- 
lete. Petals 5, rarely fewer. Stamens in 2-3 rows-on the calyx- 
tube. Carpels 6-10, distinct. often stipitate, with two pendulous 
ovules, becoming one-seeded achenes. Stigma capitate, usually 
large. Seed small with thin membranous testa.

high, glabrous or nearly so: stipules broadly ovate, acute, laciniately 
toothed, 4-6 lines long or more; leaves ample, 5-7-lobed, the lobes acute or 
acuminate, doubly lacerate-toothed, appressed-silky on the veins beneath, 
3-6 inches long; petioles stout, with 1-5 pairs of small ovate to linear-lance- 
olate toothed leaflets below the large terminal one: inflorescence a com- 
pound cymose panicle, pubescent with short somewhat appressed hairs, 
calyx-lobes subulate, twice as long as the tube, smooth or nearly so, soon 
reflexed: petals white, elliptical, sessile, 2-3 lines long, carpels about 9,

Shrubs with simple toothed or lobed alternate leave:, mem-

doubly serrate, 1-3 inches long on. slender petioles, stellately 
soft-pubescent beneath, smooth or nearly so above: flowers on long 
slender pedicels in simple hemispherical tomentose corymbs; bracts all 
scarious; calyx-lobes triangular, apiculate, as long as the tube, shorter 
than the orbicular petals pubescent on both sides: carpels 2-5, at length 
4-6 lineslong,glabrous, 2-4-seeded; seeds slenderly and obliquely pyriform, 
a line long. Common along streams and moist places. Brit. Columbia to

toothed, about 1 inch long: flowers tew, in usually compound corymbs;
