Other Notes:
There is considerable variation within P. richardsonii. The majority of individuals collected have deeply cleft or parted leaves; but in northeastern Washington (Spokane County) the leaves are impressively narrower than this; and in north-central Oregon the leaves are elliptic and merely serrate or toothed. But the distribution of these variations is very imperfectly known and intermediates are frequent, so it has been impossible to classify any of them nomenclatorially.
