Harvey (Ballard) says that VV. aurea, pinetorum, quercetorum are all allopolyploids, therefore are all valid species. Allopolyploid= having two or more complete sets of chromosomes derived from different species.

V. pinetorum was found and photographed at approx. 8700-8,750 ft. Ask Phil Rundel what the pines were on top of Mt. Pinos. One was Limber, Pinus flexilis, but there were two others. Western Transverse Ranges, Kern Co., CA. Lemon yellow flowers with purple-brown lines on lower and typical brown-backed upper petals are small, less than half an inch, but proportional to the size of the plant. Gritty, granite soil with needle duff for organic matter, Jeffrey pine woodland.
From the 2000 catalogue of Ron Ratko: pines on Mt. Pinos mentioned in conjunction with Calochortus were, with C. venustus, the Jeffrey pine, Pinus jeffreyi, at 7,100’ and with C. invensutus at 8,800 ft. Pinus flexilis, Limber Pine. I saw both these calochortus further down the mountain than V. pinetorum.
Seeds from Ron Ratko, dull grey-brown speckled with black, 2.7 x 1.7mm.
From catalogue of Jim Archibald: Plumas Co. CA., Dixie Canyon, 1370 m. In a complex group of tap-rooted Californian endemics occurring sporadically from here south to the San Jacinto Mountains near Mexico. A plant of rather dry habitats, usually under pines, with tufts of narrow, more or less linear, wavy-edged leaves and lemon-yellow flowers with purple-brown veining and on the backs of the petals.
Smithsonian herbarium has isotype:
Viola pinetorum Greene, E.L., Pittonia 2:14. 1889 – Isotype (Violaceae)
COLLECTION: Greene, E.L. s.n., 25 Jun 1889. USA. California. Kern. Tehachapi.
VERIFICATION: Specimen compared to the original publication.
US SHEET NO.: 00007422 BAR CODE: 00114596
The photograph of the type specimen looks more like the plants I photographed out of flower further down Mt. Pinos, so this may not be a hybrid with aurea as I thought.

Jul 1999, Viola pinetorum ssp. grisea, location Kern Plateau (Kern County, California), see copy of photo in this file, OR is this just V. pinetorum?? Or is the one I photographed ssp. grisea? Yes, maybe when I look at the location map for the counties of California most of the occurrences are further east especially towards the border with Nevada around Lake Tahoe. See plants.usda.gov for this info. Maps will not print out.
Viola pinetorum ssp. pinetorum only in the Alpine El Dorado, Fresno, Kern, Mariposa Nevada, Placer, Sierra, Tulare and Ventura counties, NOT in Inyo or San Bernardino counties.
Viola pinetorum ssp. grisea only in Fresno, Inyo, Kern, San Bernardino and Tulare counties.
Therefore, look for the latter, Viola pinetorum ssp. grisea in Inyo or San Bernardino counties, both on the eastern border of California.
