Nuphar polysepala
Also called Rocky Mountain Pond Lily, American Yellow Pond Lily, Rocky Mountain Spatterdock, Western Yellow Pond Lily
Nuphar polysepala, also known as the great yellow pond-lily, wokas, or wocus, is a perennial, rhizomatous, aquatic herb in the genus Nuphar. It has floating green leaves and yellow flowers.
The species is native to wetlands of western North America. The seeds are edible and the plant has been used in traditional medicine to treat superficial irritations.
It is native to western North America. It is commonly found in shallow muddy ponds from northern Alaska and Yukon southward to central California and northern New Mexico, and can be recognized easily by its large floating leaves and bright yellow blossoms.
The seeds are edible; they pop like popcorn, and can be steamed as a vegetable, dried and ground for flour, or can be cooked like oatmeal. Historically they have been a significant source of carbohydrates for the Klamath and Modoc peoples who inhabit the area near Oregon's Upper Klamath Lake.
