Of conservation concern. Physaria eriocarpa is known from Sheep Mountain. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Physaria nelsonii is morphologically similar to 73. P. pycnantha, which traditionally was included in a broader P. nelsonii. These allopatric species are distinguished by styles equal to or exceeding the length of fruit and fruiting stems overtopped by basal leaves (P. nelsonii) versus styles shorter than fruits and fruiting stems usually exserted beyond basal leaves (P. pycnantha).
