Physaria hitchcockii subsp. hitchcockii

Treatment appears in FNA Volume 7. Treatment on page 643.

Plants forming tufts; caudex not elongated, not elastic. Basal leaves: petiole differentiated from blade (sometimes weakly); blade oblanceolate to obovate. Anthers 1.4–1.8 (–2) mm. Fruits 2.6–3.8 mm wide.


Phenology: Flowering Jun–Jul.
Habitat: Gravelly or rocky limestone at or above timberline
Elevation: 2300-3500 m

Discussion

It is possible that populations of subsp. hitchcockii on the Table Cliff Plateau, Utah, are consubspecific with the nearby subsp. rubicundula. The leaf blades are indistinguishable from the material from Nevada and the plants do not form elongated, elastic caudices.

Subspecies hitchcockii is found in the Sheep Range and Spring Mountains (Charleston Mountain), Nevada, and on the Table Cliff Plateau, Utah, where it is limited to the white member of the limestone Wasatch (Claron) Formation.
