Rosa carolina aculeata Schuette, Proc. Am. Assoc. Adv. Sci. 46: 279. 1898. 
Stems usually tall, 0.3-2 m. high, erect, sometimes reddish, glabrous, terete, armed with 
strong but rather short, more or less curved prickles, which are usually paired, flattened at 
the base, 4-6 mm. long; floral branches 1-3 dm. long, glabrous, prickly or unarmed; stipules 
adnate, 2-3 cm. long, usually narrow, only the upper somewhat dilated, somewhat enrolled, 
usually pubescent beneath, somewhat glandular-denticulate or naked on the margins, the free 
portion lanceolate or subulate, usually somewhat spreading; petioles and rachis pubescent, 
rarely prickly, not glandular or rarely slightly so; free portion of the petioles above the stipules 
very short, 3-8 mm. long; leaflets 7, rarely 9, dull and dark-green, glabrous or nearly so above, 
paler and more or less finely appressed-puberulent beneath, at least on the veins, short-petiolate, 
lance-elliptic or oblanceolate, on vigorous shoots sometimes elliptic, usually acute at both ends, 
2-6 cm. long, finely and closely serrulate, with simple non-glandular teeth; flowers usually 
corymbose, sometimes solitary, leafy-bracted; pedicels short, 1-2 (rarely 3) cm. long, usually 
glandular-hispid; hypanthium subglobose or somewhat depressed, glandular-hispid, usually 
acute at the base, in fruit 10-12 mm. broad; sepals narrowly lanceolate, caudate-attenuate, 
2—2.5 cm. long, sometimes with foliaceous tips, glandular-hispid on the back, tomentose within 
and on the margins, reflexed or spreading after anthesis, soon deciduous; petals obcordate, 
rose-colored, 1.5—2 cm. long; styles distinct, numerous, not exserted, persistent; achenes 
attached mainly in the bottom of the hypanthium. 
TYPE LOCALITY: Not given, but by inference Pennsylvania.

Rosa carolina X palustris (Rosa humilis gracilis Porter, MS.). This resembles R. palustris 
in the narrow, rather firm and finely serrulate leaflets and the curved prickles; but the prickles are 
more slender or sometimes none, the flowers usually solitary and the habit of the plant is more 
like that of R. carolina. Island Park, above Easton, Pennsylvania, July 18, 1899, Porter. New 
Hampshire, New Jersey, and Pennsylvania. 
Rosa johannensis < palustris? Resembling R. johannensis in habit, but stricter, with hypan- 
thium more or less bristly, and leaflets inclined to be narrower, thicker, and finely pubescent beneath. 
Portage Lake, Maine, August 9, 1901, Robinson & Fernald (Gray Herb.). 
Rosa nitida < palustris. (R. carolina X nitida Crépin, Rhodora 2: 113. 1900. R _ carolina 
seligera Crépin, Rhodora loc. cit.) ‘This resembles R. carolina in the finely serrate and dark leaflets, 
but the leaves are more shining and the stem and branches are bristly and the prickles are more 
straight. Muddy shore, Foxcroft, Maine. 
Rosa palustris X serrulata. Resembling R. palustris in habit and inflorescence, but the leaflets 
are shorter, thinner, and glandular double-serrate, and the stipules, petioles, and rachis also glan- 
dular-hispid. Fort Howard, Wisconsin, 1894, Schuette (Gray Herb.). 
Rosa palustris < virginiana. This has the short curved prickles of R. palustris, but the leaves 
are more shining, broader and sharper toothed, approaching R. virginiana. Palisades, New Jersey, 
August, 1890, Southworth. Maine, New York, and New Jersey, near the coast.

Rosa foliolosa T. & G. Fl. N. Am. 1; 460, in small part. 1840. 
Stem low, 1 m. hich or less, with spreading branches, reddish, glabrous, terete, armed 
with short curved prickles, which are somewhat flattened at the base, 3-5 mm. long; floral 
branches spreading, flexuose; stipules adnate, about 1 cm. long, narrow, glabrous or nearly so, 
usually entire; free portion short, lanceolate, ascending; petioles and rachis glabrous or slightly 
pubescent, unarmed; leaflets 5, dull and dark-green and glabrous above, somewhat paler and 
usually wholly glabrous beneath, 1-4 cm. long, acute at each end, finely and closely serrulate, 
with simple, non-glandular teeth; flowers usually solitary, rarely in pairs; pedicels 1-2 em. 
long, usually glandular; hypanthium globose or somewhat depressed, glandular-hispid, in 
fruit 8-9 mm. thick; sepals linear-lanceolate, caudate-attenuate, 2-2.5 em. long, glandular- 
hispid on the back, tomentose on the margins, reflexed after anthesis and soon deciduous; 
petals obcordate, 1.5—-2 cm. long, rose-colored; styles distinct, numerous, not exserted, per-
