Psilocarphus oregonus Nutt. [FNA19, H&C]
Asteraceae
Oregon woollyheads

Origin: Native

Voucher:WTU (view specimen records)

Notes: FNA19: "Psilocarphus oregonus occurs from west-central California through most of Oregon to southeastern Washington, western Idaho, and northern Nevada. Relatively narrow-leaved, montane forms of P. tenellus account for reports of P. oregonus from the southern Sierra Nevada to Baja California; further study may show these to be intermediates between the two taxa."
