Hab. in America septentrionali, Masson (v. v. c. hort. Sabine et s. sp. herb. Banks.)

A shrub three or four feet high. Rootshoots ascending, straight; branches bright green, without down, sparingly armed with scattered. falcate prickles. Leaves distant; stipules very long, narrow, naked, fringed with glands; petiole naked, sparingly prickly; leaflets about 5, ovate, acute, simply serrated, serratures diverging; bright green, naked and somewhat, shining above, very much paler and downy beneath. Flowers small, pale red, about three together; peduncle and calyx without pubescence; the former glandular: sepals simple, ovate, hairy, reflexed, deciduous; stamens deciduous; styles united into a downy, clavate column. Fruit about the size of a pea, quite round and naked.

This has hitherto been considered a very obscure plant, depending almost entirely upon the authority of the Hortus Kewensis, in the last edition of which it was described by Mr. Brown from plants raised from heps sent by Masson from North America. It is a very distinct species, having little affinity with any other than R. moschata. From this its naked branchlets, peduncle and calyx will immediately distinguish it without recurring to other characters. Its habit is the same, but size less. The flowers, too, are pale red and very small; quite unlike those of moschata.

The variety fenestralis differs from the true rubifolia in the total absence of pubescence on the leaves, in their paler colour and thinner texture. My figure was taken from an unusually weak specimen and does not present the most common appearance of the plant. The flowers grow generally three or four together.

Div. XI. Banksianae. Stipulae subliberae, subulatae v. angustissimae, saepius deciduae. Foliola saepius ternata, nitida. Caules scandentes.
The species of this division are remarkable for their long, graceful, often climbing shoots, drooping white flowers, and ternate shining leaves. Their distinguishing mark is the deciduous, subulate, or very narrow stipulae. Their fruit is various. R. hystrix has setigerous branchlets, and R. setigera has united styles.

73. ROSA setigera.

R. sepalis pinnatifido-setigeris, stylis coalitis, fructibus muricatis.

R. setigera Mich. bor. am. 1. 295. Pers. syn. 2. 48. Pursh am. septr. 1. n. 7. Smith in Rees in l.

Hab. in America septentrionali, (Michaux).

Stem erect, smooth, armed beneath the stipulae with 1-3 short, recurved prickles. Stipules subulate; petiole rough with setae and little recurved prickles; leaflets 3-(rarely)-5, oval, usually with a point, acutely serrated, smooth. Flowers numerous, or sometimes solitary, rose-coloured; stalks long, rough with setae; tube of the calyx round, rough; sepals with a very narrow, sharp point, somewhat pinnatifidly setigerous, downy and glandular: petals broad, obcordate; styles twice as long as the tube of the calyx, twisted together into a smooth column. Fruit globose, rough. Ach. Richard's MSS.

For the foregoing account of this very little known species, I am much indebted to M. Achille Richard, who has taken the trouble to examine the herbarium of Michaux for the purpose. Its united styles distinguish it from the rest of this division.

CybeRose note: Rosa setigera does not have subulate stipules. The only Rosa species that Michaux could have collected in North America that had subulate stipules was the introduced R. laevigata. Perhaps a leaf of this species became associated with the flower of R. setigera, thus creating a bogus species.
