The PRAIRIE, CLIMBING, or MICHIGAN ROSE (R. setigera) lifts clusters of deep, bright pink flowers, that after a while fade almost white, above the thickets and rich prairie soil, from southern Ontario and Wisconsin to the Gulf, as far eastward as Florida. Its distinguishing characteristics are: Stout, widely separated prickles along the stem, that grows several feet long; leaves compounded of three, rarely five, oval leaflets, acute or obtuse at the apex; stalks and calyx often glandular; odorless flowers that, opening in June and July, measure about two and a half inches across, their styles cohering in a smooth column on which bees are tempted to alight; and a round hip, or seed vessel, formed by the fruiting calyx, which is more or less glandular. From this parent stock several valuable double-flowering roses have been derived, among others the Queen and the Gem of the Prairies, but it is our only native rose that has ever passed into cultivation. The SMOOTH, EARLY, or MEADOW ROSE (R. blanda), found blooming in June and July in moist, rocky places from Newfoundland to New Jersey and a thousand miles westward, has a trifle larger and slightly fragrant flowers, at first pink, later pure white. Their styles are separate, not cohering in a column nor projecting as in the climbing rose. This is a leafy, low bush mostly less than three feet high; it is either entirely unarmed, or else provided with only a few weak prickles; the stipules are rather broad, and the leaf is compounded of from five to seven oval, blunt, and pale green leaflets, often hoary below. In swamps and low wet ground from Quebec to Florida, and westward to the Mississippi, the SWAMP ROSE (R. Carolina) blooms late in May and on to midsummer. The bush may grow taller than a man, or perhaps only a foot high. It is armed with stout, hooked, rather distant prickles, and few or no bristles. The leaflets, from five to nine, but usually seven, to a leaf, are smooth, pale, or perhaps hairy beneath to protect the pores from filling with moisture arising from the wet ground. Long, sharp calyx lobes, which drop off before the cup swells in fruit into a round, glandular, hairy red hip, are conspicuous among the clustered pink flowers and buds. Surely no description of our COMMON, LOW, DWARF, or PASTURE ROSE (R. humilis; R. lucida of Gray) is needed. One's acquaintance with flowers must be limited indeed, if it does not include this most abundant of all the wild roses from Ontario to Georgia, and westward to Wisconsin. In light, dry, or rocky soil we find the exquisite, but usually solitary, blossom late in May until July, and, like most roses, it has the pleasant practice of putting forth a stray blossom or two in early autumn. The stamens of this species are turned outward so strongly that self- pollination must very rarely take place.
