80 RYDBERG: NOTES ON ROSACEAE 
25. Rosa Copelandii Greene, sp. nov. 
Stem dark purple, terete, shining, sparingly armed with straight 
infrastipular prickles, which are about 5 mm. long, rather stout 
and somewhat flattened below; floral branches 1-2 dm. long, 
purple, more or less armed; stipules 1-2 cm. long, adnate, gla- 
brous, more or less dilated, thin, often tinged with purple; free 
portion semi-lunate, acuminate; petiole and rachis glabrous, often 
slightly prickly, purplish; leaflets five or seven, oval or elliptic, 
thin, perfectly glabrous on both sides, finely serrate, 1-3 cm. long; 
flowers corymbose; pedicels glabrous, short, I-1.5 cm. long; hypan- 
thium glabrous, urn-shaped, rounded at the base, prolonged above 
into a distinct neck, in fruit 9-10 mm. thick, 10-12 mm. long; 
sepals lanceolate, about 15 mm. long, caudate-attenuate, glabrous 
on the back, tomentose on the margins, in fruit erect and persist- 
ent; achenes inserted in and near the bottom of the hypan- 
thium. 
Dr. Greene recognized this species, but for some reason did 
not publish it. It is characterized by its ovoid urn-shaped hypan- 
thium, with a conspicuous neck, and glabrous leaves.

26. Rosa pilifera Rydberg, sp. nov. 
Stem 1 m. high or more, at first yellowish, in age dark gray, 
terete, armed with straight infrastipular and scattered prickles 
3-5 mm. long, somewhat flattened below; floral branches 1-3 dm. 
long, usually sparingly armed; stipules adnate, the lower narrow, 
the upper dilated, 1-1.5 cm. long, pilose and glandular on the back, 
glandular-ciliolate on the margins; free portion linear-lanceolate 
to ovate, ascending; petiole and rachis pilose, glandular and some- 
times with a few weak prickles; leaflets five to seven, thin, oval, 
2-3.5 cm. long, sparingly pilose above, more densely so and some- 
what glandular-pruinose beneath, usually more or less double- 
toothed and the teeth often gland-tipped; flowers corymbose; ped- 
icels 1-3 cm. long, more or less pilose; hypanthium ellipsoid, with 
a neck, pilose at least when young, in fruit 8-1o mm. thick,

long, more or less pilose, in fruit erect; petals about 1.5 cm. long; 
styles distinct, persistent, not exserted. 
This species has the leaflets of R. Aldersonii, i. e., double-toothed 
and glandular beneath, but they are thinner, the prickles are 
slender, straight, or rarely slightly curved, and the young hypan-
