Rosa woodsii Lindley subsp. gratissima (Greene) W. H. Lewis & Ertter, Novon. 17: 351. 2007.
Mojave or Tehachapi rose
Rosa gratissima Greene, Fl. Francisc., 73. 1891; R. pisocarpa A. Gray var. gratissima (Greene) Jepson; R. woodsii var. gratissima (Greene) D. Cole
Description...
Within subsp. gratissima, localized clusters of glabrous populations on the northern foot of the San Bernardino Mountains represent var. glabrata (Parish) D. Cole (basionym R. californica Chamisso & Schlechtendal var. glabrata Parish); R. mohavensis Parish is a homotypic synonym and R. woodsii var. mohavensis (Parish) Jepson is superfluous and illegitimate. Conservative attention to var. glabrata is warranted. The remainder of subsp. gratissima is var. gratissima. A. Cronquist and N. H. Holmgren (1997) identified the NY syntype of R. gratissima as R. californica; the holotype (NDG 23620) clearly falls within the circumscription here.

Rosa woodsii Lindley, Ros. Monogr. 21. 1820....
Key to the subspecies of Rosa woodsii in Central and Western North America:
- Shrubs most frequently tall, 1-3 (-5) m; flowering branches unarmed or with straight or curved prickles; terminal leaflets ovate to elliptic, fewer obovate; flowers 1 or 2 or corymbose and then 3 to 10 (to 15); western North America including the far Southwest.
-- Prickles straight or occasionally somewhat curved, absent or few to dense; flowers few, 3 most common or numerous (to 15); sepals eglandular or infrequently stipitate-glandular; intermontane between Cascade and Rocky Mtns. of British Columbia to southern Great Basin and mountains of Majave Desert, and east to Rocky Mtns.
--- Stems densely branching; prickles stout and often long, straight or curved, sometimes infrastipular and often dense and varying in size intermodally; SW Great Basin, Mojave Desert and adjacent mountains...subsp. gratissima.

Rosa woodsii Lindley subsp. gratissima (Greene) W.H. Lewis & Ertter
synonyms: Rosa gratissima Greene; Rosa pisocarpa var. gratissima (Greene) Jepson; Rosa woodsii var. gratissima (Greene) D.Cole
Rosa woodsii subsp. gratissima occurs in springs and along streams in the mountains in and surrounding the Mojave Desert and southern Great Basin, from the east side of the Sierra Nevada in Mono County, California, east to Eureka County,...south to ...Nye county [Nevada] and the north slope of the San Bernardino Mountains and San Gabriel Mountains and Mount Pinos in southern California. This is also the characteristic subspecies in the southern Sierra Nevada from Fresno County southward, and populations occur in the White Mountains on the California-Nevada border and the Panamint Mountains west of Death Valley.

Rosa woodsii Lindl. var. gratissima (Greene) Cole prepared by Guy Nesom
Shrubs growing .2 -2 or 3 m high, sometimes forming impenetrable thickets. Stems reddish-brown to gray, with straight or slightly curved prickles. Leaflets 5-7, ovate or elliptic, finely toothed toward the tip. Flowers on branches lateral from old wood, 5 petals, pink to lilac pink or lavender; sepals lanceolate 1-2 cm long, erect and persistent. Hip is globose. Distinguished from similar species by shrubby, thicket-forming habit, stems with straight prickles and leaves and sepals without glands. Named for Joseph Woods, 1776-1864, English student of roses.
Native to California and Nevada.
Produces flowers at 2-5 years of age with a good crop every 2 years. Seed is viable 2-5 years.
var. ultramontana is the far-western entity, sometimes regarded as including var. glabrata (California endemic) and var. gratissima (California and Nevada).
