Lemon sagewort, Michaux's wormwood
Mostly in and around the Great Basin, and the Rocky Mountain states
Scree slops, rocky places, streambanks; up to 12,000 feet
Yellowish-green, up to 4 inches long, irregularly pinnately divided into flat, sharp-lobed leaflets
The common name of artemisia michauxiana, lemon sagewort, refers to its distinctive lemony scent, and the yellowish tint to the stems and leaves. Stems are rigid, and grooved, while leaves are divided into well-separated, sharp-pointed lobes. Leaves tend to be hairless on the upper surface, and dotted with a few yellow glands, and sparsely hairy underneath.
Flowerheads form in short, narrow clusters at the upper leaf nodes, and are pendent when open. Florets are reddish in bud, yellow at maturity, and consist of around ten staminate florets and from 15 to 35 disc florets, which have both stamens and pistils. The hairless phyllaries are yellow-green in color (less often purplish) and ovate in shape, in one series.
