Rosa foliolosa (Species)

Rosa foliolosa

THE Prairie Rose of the south-west is one of the more distinctly marked species of the genus as represented in America. In habit it is low, rarely more than a foot in height, spreading by running root-stocks and forming clumps. The stems are slender and leafy, often unarmed; the spines, when present, mostly slender and straight, or nearly so. The leaves are nearly or quite glabrous, pale green and shining above, of seven to eleven small, narrow leaflets, which are acute at both ends, or only acutish at the apex, and simply toothed. The narrow stipules are usually glandular-ciliate, and the stalk of the leaf prickly. The rather large flowers are bright pink and very fragrant, almost always solitary and on quite short pedicels. The depressed-globose hip and the sepals are glandular-hispid, and the outer sepals narrowly lobed.

This little Rose was first collected by Thomas Nuttall during his early visit to Arkansas in 1818-20, but was not published until twenty years afterward, when it was described in Torrey and Gray's "Flora of North America" (vol. i., p. 460). Meantime it had been found by Berlandier and Drummond in Texas, and by other collectors. It appears to be confined to the prairie region of Arkansas, the Indian Territory, and northern and central Texas. A nearly allied species (R. Mexicana), found by Dr. Palmer in the mountains of Coahuila, Mexico, is the only species known to be native in Mexico proper.

The accompanying figure, on page 101, was drawn by Mr. Faxon from a specimen cultivated at the Arnold Arboretum. — S. W.

9. R. foliolosa (Nutt. ! mss.) : branches slender, glabrous, armed with very weak scattered deciduous bristly prickles, and sometimes with persistent short and nearly straight stipular prickles; leaflets 7-11, linear-oblong, glabrous, shining above, sharply serrate, crowded, the lower pair close to the narrow glandular-ciliate stipules; the petiole and midrib often setose and pubescent ; flowers mostly solitary and almost sessile ; calyx glandular-hispid ; the segments reflexed, often with lateral appendages; "fruit subglobose, somewhat hispid.

Prairies of Arkansas, Nuttall ! Dr. Pitcher ! Dr. Leavenworth ! Texas, Drummond ! East Florida ? — A remarkable species, with the leaves much crowded on the flowering branches and often fascicled: leaflets sometimes only half an inch in length. Flowers small, apparently rose-color; the peduncles 1/4-1/2 an inch in length.

CybeRose note: Rydberg separated the East Florida specimen as R. floridana.

Garden and Forest (Oct. 30, 1886)
Rosa Foliolosa comes from Texas, and is among the latest species to bloom. Its pale lemon-coloured flowers begin to open in July and continue until September. It is seldom seen in cultivation, but its fine, distinct foliage and apparent hardiness commend it. Its features are all so marked that the hybridisers ought to experiment with it. Its blood, mingled with that of other types, might produce a new and worthy race.
