Rosa adenocarpa Dwarf and almost herbaceous, simple and upright above the almost entirely subterranean woody part, only 4 to 7 inches high, with about 4 leaves and 1 to 3 terminal small flowers; stem slender, wholly glabrous and unarmed, or in a few with here and there a short stout straight prickle: leaflets 5, rarely 7, very unequal, very broadly obovate to nearly orbicular, petiolulate, coarsely, incisely and somewhat doubly serrate, apparently glabrous...rachis...destitute of prickles but quite densely glandular-villous; stipules not very broad, their lobes...strongly glandular-serrulate; fruit quite strongly armed with gland-tipped prickles.
Singular species, despite all its peculiar characteristics, a genuine member of this gymnocarpous group, known only as collected on Mount Grayback in southwestern Oregon, 15 June, by C.V. Piper.

In "Certain American Roses": In the course of two thousand years' history of the genus Rosa perhaps no more remarkable taxonomic discovery was ever made than that which fell to the lot of Dr. C.C. Parry and his party in 1882, when, botanizing along the seaboard of the Mexican Territory of Lower California, they came upon the unknown shrub which Dr. Engelmann soon after published as Rosa minutifolia....During some fifteen years this Lower Californian curiosity remained practically a monotypic subgenus. Then in 1897, not much less than a thousand miles inland..., Mr. Wooton discovered in the mountains of New Mexico, at elevations of 5,000 to 6,000 feet, what he regarded as a second member of this strange group, and he published it as Rosa stellata....The excellent specimens of R. stellata distributed by Mr. Wooton are from two separate and rather well isolated mountain ranges in southern New Mexico.... the Rosa stellata of the Organ Mountains and that of the Sierra Blanca are so very different in characters of stem, spines, leaves and indument that....they must be held specifically distinct...
Rosa mirifica Growing stems light-green without stellate or any other hairiness, the few stout white prickles supplemented by very many intervening short almost filiform recurved and gland-tipped prickles: leaflets more commonly 5, of at least twice the size of those of R. stellata, strongly cuneate-obovate...glabrous on both faces...stipules long....the whole stipule marginally beset with small sessile glands.
There is now before me a third representative of this strange group of roses....from a region of the southward of New Mexico, taken by a zoological traveler in another isolated range, the Guadalupe Mountains of Texas....I name the species Rosa Veronii. Next of kin to true R. stellata but growing twigs....the peduncles...villous-silky; large spines more slender...Known only as collected in the Guadalupe Mountains, Texas, by Mr. Vernon Bailey, 15 Aug. 1901.
