Perennial herbs with palmately lobed or pinnate, alternate 

 leaves, foliaceous persistent stipules and numerous small flowers 

 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 aclienes. Stigma capitate, usually 

 large. Seed small with thin membranous testa. 



F. occid en tails. Spirxa occidentals Watson. Stems simple, 2-6 feet 

 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, 

 erect, narrowly lanceolate, long-stipitate, beaked by the elongated style, 

 villous on the margins from the summit of the style to the base. Rocky

Shrubs with simple toothed or lobed alternate leaver, mem- 

 branaceous deciduous stipules and rather large white flowers in

 Watson. A shrub 3-20 feet high with slender spreading or recurved 

 branches and ash-colored shreddy bark : stipules linear, 5-6 lines long, re- 

 motely toothed, caducous; leaves roundish, often subcordate, 3-lobed, 

 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 lines long,glabrous, 2-4-seeded; seeds slenderly and obliquely pyriform, 

 a line long. Common along streams and moist places. Brit. Columbia to 

 California and the Rocky Mountains. 



N. Tprreyi Watson Proc. Am. Acad. xi, 136. A small shrub, barely 

 2 feet high, erect, scarcely surculose, freely branching : leaves of rather 

 deltoid-ovate outline, incisely 3-lobed to the middle, the lobes nearly 

 equal, the whole with slight secondary lobes, these crenately or incisely 

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

 petals comparatively large, often rose-tinted ; carpels mostlv 2, coherent to 

 above the middle, but littie longer than the calyx, divergent at apex, only 

 slightly inflated, minutely tomentose, 1-seeded : seeds obovoid. In dry

 Rocky Mountains.
