123. Rosa mirifica Greene, Leaflets 2: 62. 1910. 
Stem 4-6 dm. high, much branched, armed with numerous straight or somewhat curved 
prickles and bristles, which are 2-10 mm. long, sometimes slightly glandular-hispid, but not 
stellate; leaves 3-foliolate or on the shoots and the more vigorous branches 5-foliolate; stipules 
adnate, 6-10 mm. long, often glandular-dentate, the free portion oblong and spreading; petiole 
and rachis mostly glabrate; leaflets cuneate-obovate, rounded at the apex, with 7-10 rounded 
teeth above the middle, pilose or glabrate, 8-15 mm. long; flowers solitary, terminal; pedicels 
about 1 cm. long; hypanthium globose, in fruit about 15 mm. in diameter, covered with nu- 
merous prickles; sepals lanceolate, about 2 cm. long, caudate-acuminate, usually with foliaceous 
tips, the outer more or less lobed, prickly on the backs, ciliate on the margins and tomentose 
within, in fruit persistent and erect; petals deeply rose-purple, 2.5-3 cm. long; pistils numerous; 
styles not exserted, distinct, persistent; achenes in the bottom of the hypanthium. 
TYPE LOCALITY: Sierra Blanca (White Mountains), New Mexico. 
DISTRIBUTION: White and Sacramento Mountains, New Mexico. 
ILLUSTRATION: Bull. Torrey Club 25: pl. 335, f. 6-8. 
XI. Gymnocarpae. Slender shrubs more or less bristly and with infrastipular spines 
scarcely stronger than the bristles; stipules adnate, the upper ones dilated; leaflets 5—7, usually 
double-serrate; flowers solitary or few together; sepals short, falling off together with the 
upper part of the hypanthium and the styles; achenes very few; styles scarcely exserted. 
124. Rosa dasypoda Greene, Leaflets 2: 260. 1912. 
Stem green or purplish, rather stout for the group, more or less bristly and with bristle- 
like infrastipular prickles 5-8 mm. long; leaves 5—9-foliolate; stipules adnate, mostly broad, 
the upper ones conspicuously dilated, glandular-ciliate as well as glandular on the back; petioles 
and rachis glandular-hispid and somewhat bristly; leaflets broadly oval to suborbicular, 
rounded at both ends or acute at the apex, glandular double-toothed, with broadly ovate 
teeth, the upper 2—4 cm., the lower 1—2 cm. long, glabrous on both sides or slightly glandular 
on the ribs beneath, dark-green above, paler beneath, indistinctly reticulate; flowers 2—4- 
together, subtended by leaves or enlarged stipule-like bracts; pedicels 2-3 cm. long, conspicu- 
ously glandular-hispid; hypanthium at first broadly ellipsoid, in fruit almost globular, 6-8 mm. 
in diameter, glabrous; sepals ovate, abruptly acuminate, about 1 cm. long, glabrous on the 
back, tomentose within and on the margins, deciduous together with the upper part of the 
hypanthium; petals 12-14 mm. long, broadly obcordate; styles few, distinct, deciduous; 
achenes large.

TYPE LOCALITY: Bear Creek, Wallowa County, Oregon. 
DISTRIBUTION: British Columbia to California, near the coast. 
125. Rosa leucopsis Greene, Leaflets 2: 258. 1912. 
Rosa Helleri Greene, Leaflets 2: 259. 1912. 
Stem 1 m. high or more, stoutish, pale-green or brownish, usually sparingly bristly, with 
ascending bristles; branches often unarmed; leaves 5-—7-foliolate; stipules short, 1 cm. long, 
narrow or the upper somewhat dilated, glandular-ciliate and glandular on the back; petioles 
and rachis glandular-hispid and somewhat bristly; leaflets oval or obovate in outline, often 
rounded at both ends, deeply double-serrate with glandular ovate-lanceolate teeth, glabrous 
on both sides, somewhat pale-green above, still paler, indistinctly reticulate, and slightly 
glandular on the ribs beneath; flowers solitary; pedicels sparingly glandular-hispid; hypan- 
thium glabrous, at first ellipsoid, often becoming subglobose or pear-shaped in fruit, then 
4-6 mm. in diameter; sepals ovate or lance-ovate, abruptly acuminate, glabrous on the back, 
tomentose on the margins and within, scarcely 1 cm. long; petals obcordate, 10-12 mm. 
long; deciduous together with the upper part of the hypanthium; achenes few; styles dis- 
tinct, deciduous. [Perhaps not distinct from R. gymnocarpa.] 
TYPE LOCALITY: Sage plains of southeastern Oregon, in Lake County. 
DISTRIBUTION: Montana to Oregon and British Columbia.
