Eriogonum umbellatum Torr. var. ellipticum (Nutt.) Reveal[FNA5, HC2]
sulfur flower

Publication: Taxon. 32: 294. 1983.

Origin: Native

selected vouchers: WTU

Notes: FNA5: "Variety ellipticum is widely scattered but locally common in the mountains of the Pacific Northwest. It has long been known as var. stellatum, the name being altered to var. ellipticum only for technical nomenclatural reasons. This is the northern phase of the species, with compound inflorescences. Considerable variation in plant size is retained within the circumscription adopted here. Plants from northeastern Oregon and adjacent west-central Idaho are large and showy, and it is this phase (called Eriogonum croceum or E. umbellatum var. chrysanthum) that occasionally is seen in cultivation."
