Rosa Arkansana Suffulta=R.suffulta Greene
I found this abundant at Las Vegas [New Mexico] between the town and the Hot Springs. The stipular leaflets are as described by Greene.

Rosa blanda Ait. var. arkansana (Porter). Although frequently observed before, it was first described by Dr. Porter as Rosa Arkansana from specimens collected on the banks of the Arkansas River by Mr. Brandagee. The original specimen, in flower, is in the herbarium of Lafayette College.

In Notes on Rosaceae. Axel Rydberg: Rosa Brownii Rydberg
Stem...glabrous, green or brownish, armed with slend straight prickles...leaves five- to seven-foliate; stipules ovate, acute; petiole and rachis finely pilose (ed.: covered with soft, fine hair) and more or less glandular; leaflets thin...some of the teeth double...glabrate above, paler, pilose and slightly glandular-muricate beneath; flowers mostly solitary;...hypanthium globose...sepals...usually with foliaceous tips...petals broadly obovate, rose-colored...
This species resembles somewhat R. nutkana, but the prickles are weak, not at all flattened....Much of the Californian material determined as R. nutkana belongs here. California: North side of Mt. Shasta, 1897, H.E. Brown...Humboldt Bay, 1901, Chanlder...Mendecino (sic) 1903, McMurphy.

Best: These remarks are based on an examination of the large and valuable collection of the Geological and Natural History Survey of Canada,...the collections of Lafayette College...,and the Philadelphia Academy of Natural Sciences...
1. Rosa gymnocarpa Nuttal, 1840, ranges from British Columbia to California, and eastward to Idaho and Montana. Its peculiar dehiscence [the hips open and release their seeds at maturity], so far as is known, distinguishes it from all other North American roses. Two Asiatic species, Rosa Albertii ...and Rosa Beggeriana ...are, as I am informed by M. Crépin, the only roses of this sub-group in the Old World. To know the actual relations of these three closely allied species would be extremely interesting.

"A New North American Rose by C.C. Parry"
On a recent botanical excursion in the upper part of Lower California, between the 5th and 15th of April of the present year (1882),...a remarkable new species of Rosa was met...Specimens were shortly afterward sent to Dr. Engelmann, of St. Louis, who, at the request of three of the discoverers, Mr. Pringle, Mr. Orcutt and myself, has kindly furnished the following diagnosis and description.....
Rosa minutifolia A much-branched shrub, 2-4 feet high; shoots pubescent, densely covered with straight or slightly recurved, red-brown, bristly...spines...leaves...on short spure...leaflets minute (only 1-2 lines long [a line was 1/12th of an inch], the lowest pair the smallest) oval, simply ...dentate, pubescent, not glandular; flowers single, ¾-1 inch wide...calyx-tube ...densely setose-hispid...petals...rose-purple or white....A most striking and lovely species, distinguished from all other roses by its minute, deeply incised leaflets....fragrance faint....This species is quite peculiar among its American congeners, and even among the roses of the Old World...G. Engelmann

Rosa oreophila sp. nov. [new species]
A shrub 2-3 m. high ; bark reddish, glossy ; prickles mostly infrastipular or lacking, weak, 5 mm. long or less, curved with elliptic bases ; stipules broad, finely pubescent and glandular-denticulate on the margin; free portion ovate, 5—15 mm. long; leaves 7-10 cm. long, 5-7-foliolate ; rachis and petiole finely pubescent and with sessile glands ; leaflets 2—3.5 mm - long, ovate or oval, acute or obtuse, glabrous and dark green above, sparingly and finely pubescent and paler beneath, coarsely serrate ; flowers mostly solitary ; sepals narrowly lanceolate, acuminate, finely pubescent on both sides and glandular-denticulate on the margins, erect and persistent in fruit; petals obcordate, 2—2.5 cm - .....hip glabrous, when ripe fully 2 cm. long, often acute at the base.
This is perhaps nearest related to the preceding, but differs in the smooth and more rounded fruit and more slender prickles. It grows at an altitude of 2,300—2,500 m.

in "A New Southwestern Rose" by E.O.Wooton
The species Rosa stellata is particularly interesting as being the second member of ...the...section Minutifoliae of Crepin. While agreeing in most particulars...to this section...it can hardly be said to have appendiculate outer sepals nor is the pubescence of the receptacle long.
While closely related to Rosa minutifolia Engelm., it is easily separated from that species by its less numerous and larger hips with fewer and smaller spines. The stellate trichomes, referred to in the name I have given it, are most unique and interesting in this genus.
Shrub, 4-6 dm. high, much branched. Stems stiff, beset with numerous straight or slightly curved yellowish spines, young stems closely covered with stellate trichomes [star-shaped hairs]....leaves small...3-5 foliolate...leaflets triangular...cuneate...cut into 5-8 large rounded...teeth...leaflets, petiole and stipules covered by with a fine spreading silky white pubescence, not glandular; flowers large and showy, solitary, 4-7 cm. in diameter, terminal, deep rose-purple...calyx-tube globose...very finely pubescent and covered with numerous spines...fruit irregularly spheroidal, spiny...
First collected in flower near the Cueva in the Organ Mountains, New Mexico, April 30, 1893...at an altitude of about 5500 feet...A single specimen collected...in the Sacramento Mountains, N.M....There is considerable variation in the specimens collected at the different localities, those from the higher altitudes...more vigorous..., more glandular, more spiny and less pubescent...The Organ Mountain specimens are closely lepidote [ed. note: rough to the touch, scaly] on all the branches....The leaves are...finely pubescent and not....glandular...the leaflets perfectly triangular. Specimens from the White Mountains show all grades of stellate scaliness...Old stems are rarely lepidote and all are much more spiny, the stellate trichomes being replaced by numerous fine recurved spines. The leaflets...vary from triangular to obovate, and from finely pubescent to perfectly glabrous....The Fresnal specimen is perfectly glabrous on leaves and stems, but the stems are very spiny and bear numerous stipitate glands...the margins of the leaflets and stipules are very glandular; the leaflets are usually five....The absence of stellate trichomes, the more numerous spines, the generally more numerous, larger, and differently shaped leaflets, and the glandular character of this plant would seem to be sufficient to establish a well marked variety at least, but the material...seems...too scanty to warrant such action.

[From article "Rocky Mountain Flora" by Axel Rydberg]
Rosa Underwoodii sp. nov. [new species] Shrub, 1-2 m. high; bark of the old stems gray; that of the preceding year's branches purplish and of the new twigs purplish or green; prickles infrastipular and scattered, strongly curved, 7-10 mm. long, with an oblanceolate base, 5-10 mm. long; stipules narrow, the lanceolate free portion about 5 mm. long, glandular-dentate ; leaves 5-10 cm. long ; petiole and rachis puberulent and with sessile glands ; leaflets 2-4 cm. long, obovate or oval, usually obtuse, doubly serrate, glabrous on both sides or finely puberulent and slightly paler beneath ; flowers usually solitary ;
sepals lanceolate, acuminate, about 2 cm. long, erect and persistent in fruit, tomentulose above, glandular and bristly beneath, often with linear lobes; petals obcordate, about 2.5 cm. long and fully as wide ; hip in fruit more or less pear-shaped, about 3 cm. long and 2 cm. in diameter, sparingly bristly.
This species has the general habit of R Nutkana and R. Mac-Dougalii, but differs from both in the curved prickles. It has bristly fruit as theas the latter, but the fruit is more tapering at the base and the bristles fewer. It grows in the mountains at an altitude of 2,300-2,700 m.
