180 ROSACEAE. HORKELTA. 
setaceous; leaflets oblong-cuneiform, 6-8 lines long, deeply cut into 5-9 
linear-oblong or filiform segments; cauline leaves similar, with nearly free 
pinnatifid stipules and more simple leaflets with linear segments: flowers 
crowded on the branches of the almost capitate or at length open-panicu- 
late cyme; bractlets linear, shorter and much smaller than the triangular 
acuminate calyx-lobes; petals white or pinkish, cuneate-obovate, attenu- 
ate toa slender claw, 3 lines long, longer than the sepals; filaments 
broadly oblong: achenes oblique-ovoid. In high mountain valleys, 
Washington to California. 
H. pseudocapitata Rydberg 1.c.. Sparingly pilose and more or less 
glandular: stems rather slender, 6-14 inches high: leaves 2-6 inches long, 
9-15-foliolate; stipules linear or the upper ones broadly subulate; leaflets 
broadly obovate with cuneate base to narrowly cuneate, 3-8 lines long, 
more or less deeply incised and toothed with obtuse to acute teeth: flowers 
in small subcapitate cymes; bractlets linear, a line long, about half as 
long as the broadly subulate calyx-lobes; petals oblong, attenuate below 
to a short claw, retuse at the apex, about 3 lines long, but little exceeding 
the calyx, filaments triangular, obtuse. In moist meadows and along 
streams, southern base of the Blue Mountains in Oregon. 
H. capitata Lindl. Bot. Reg. under t. 1997. Somewhat glabrous: 
stems viscous-pubescent toward the summit: radical leaves about 13-folio- 
late; stipules entire or 3-parted; leaflets laciniate-incised, the lower ones 
roundish-cuneiform, the upper oblong and attenuate at base: heads of 
flowers dense, shorter than the laciniate bracts; bractlets lanceolate-subu- 
late, about as long as the calyx-lobes: petals broadly cuneiform, longer 
than the calyx. Cascade Mountains of Oregon. 
H. Hendersoni Howeli P. C. Pl. Col. 1887. Densely silky-pubescent ; 
not glandular: stems densely tufted, 4-6 inches high: simple: stipules se- 
taceous, or those of the cauline leaves lanceolate: leaves very numerous 
at the ends of the much branched caudex: leaflets 11-17, mostly crowded, 
broadly cuneate and palmately 3-5-lobed, or the lowest ones often obovate 
and entire, 1-3 lines long, flowers rather few, in compact terminal cymes, 
bractlets linear, nearly equalling the subulate calyx-lobes; petals nar- 
rowly lanceolate, about equalling the calyx; filaments broad-subulate, 
half as long as the sepals: achenes‘not seen. “On top of Ashland Butte, 
ofa Mountains, Oregon. First collected by L. F. Henderson, July 
1886. ) 
H. parvifiora Nutt. T. & G. Fl. i, 435. Tomentose; upper part of the 
stem viscidly villous: radical leaves 9-13-foliolate; stipules ovate-lanceo- 
late, small, entire or toothed: leaflets short, roundish, the upper ones 
cuneiform, incised; flowers small, much crowded on the branches of the 
fastigiate cyme; bractlets linear subulate, shorter than the narrowly tri- 
angular calyx-lobes; petals narrow, spatulate longer than the calyx. 
Plains of eastern Oregon and Washington. . 
* * Style filiform, about equalling the stamens: stipules much di- 
vided into linear iobes. 
H. congesta Dougl. Hooker Bot. Mag. t. 2880. Hirsute with long 
spreading hairs below, nearly smooth above: stems slender, erect, 6-20 
inches high or more: radical leaves 7-15-foliolate, the rachis hirsute be- 
low with long white spreading hairs: leaflets narrowly spatulate, or the 
earliest ones oblong, 6-10 lines long, 2-3-toothed at the apex, sparingly to 
densely silky both sides: flowers rather small, in open paniculate cymes; 
bractlets linear, more than half as long as the triangular-acuminate calyx- 
lobes: petals obovate, attenuate below to a narrow claw, rounded at the 
apex, 2-3 lines long, exceeding the calyx: filaments very short, triangu- 
lar: achenes ovoid, a line long, whitish. On low hills and dry prairies, 
southwestern Oregon and adjacent California. er
