Physaria newberryi
Physaria tumulosa
Subspecies 2 (2 in the flora).
Physaria newberryi, with its unusual fruits, can be confused with 15. P. chambersii. In P. chambersii, the sides of the fruit are flat, the style always exceeds the top, or shoulders, of the fruit, and shoulders form an angle that does not curve in toward the style. In P. newberryi, the sides of the fruit are concave, the styles are shorter than shoulders of the silicle (except in subsp. yesicola), and shoulders of the silicle form a curved, inward arching crown on the fruit.

Of conservation concern.
Physaria tumulosa is morphologically similar to 55. P. navajoensis of northeastern Arizona and northwestern New Mexico, and differing very subtly. It has been long treated as an infraspecific taxon of P. hitchcockii; unpublished molecular data do not support that disposition. It is found on knolls of the Winsor Member of the Carmel Formation.
