| Perennials; caudex usually simple, sometimes branched, (thick, cespitose); (silvery) pubescent throughout, trichomes few-rayed, rays furcate, sometimes slightly fused at base, (umbonate, lightly tuberculate to nearly smooth). |
Perennials; caudex (buried), branched, (dense, forming hard mats); densely pubescent, trichomes (subsessile), 8–13-rayed, rays usually furcate, distinct, (umbonate, usually tuberculate, less so over umbo). |

Physaria chambersii has been divided into three varieties based on whether the fruit is stipitate (var. canaani) or not, and whether the caudex elongates (var. sobolifera) or not (var. chambersii). In this species and in some others, e.g., P. newberryi, the latter character often depends on substrate and microclimate. Shifting substrates, such as moving sand and talus, often cause caudices to elongate. The species can be confused with 57. P. newberryi.

Of conservation concern. Physaria pulvinata is known from an area surrounded by a pygmy forest of Utah juniper in Dolores and San Miguel Counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
