Salix cascadensis Cockerell[FNA7, HC, HC2]
Cascade willow

Publication: Muhlenbergia. 3: 9. 1907.

Origin: Native

selected vouchers: WTU

Notes: FNA7: "The morphological variability of Salix cascadensis is not well understood. Typically, it has leaves that are narrow, sharply pointed, and glaucous abaxially, catkins 15-43-flowered, dark brown floral bracts, and ovaries very densely hairy. Specimens with leaves not glaucous abaxially, catkins relatively few-flowered, and ovaries either sparsely hairy throughout, hairy only on beaks, or hairy in streaks, may be hybrids but the glabrous ovaried S. cascadensis var. thompsonii shows no obvious signs of hybridization.

Hybrids:

Salix cascadensis is suspected to hybridize with S. barclayi.

Salix cascadensis × S. rotundifolia var. dodgeana resembles the former in its narrow, acute to acuminate leaves and the latter in leaves not glaucous abaxially, tawny floral bracts, relatively short catkins, and glabrous ovaries. The catkins are intermediate in being 6-7-flowered."
