Artemisia suksdorfii is similar morphologically to A. douglasiana; it has more and smaller heads, and glabrous phyllaries. The two species hybridize where their ranges overlap.

Artemisia suksdorfii

fornecido por wikipedia EN
Artemisia suksdorfii is a North American species of sagebrush in the sunflower family. It is known by the common names coastal mugwort, coastal wormwood, and Suksdorf sagewort. It is native to coastal regions from British Columbia, Washington, Oregon, and northern California as far south as Sonoma County, with isolated populations on Santa Catalina Island in Los Angeles County.[2]
Artemisia suksdorfii grows in coastal drainages and other habitat near the ocean. This is a rhizomatous perennial herb producing many erect stems one half to two meters in height. The unbranched stems are brownish and have woody bases. The leaves are narrow and lobed, green and hairless on top and white and woolly underneath. The inflorescence is generally spike-like, up to 30 centimeters long and a few wide. It contains many clusters of small flower heads with shiny yellow-green phyllaries and yellow disc and pistillate florets. The fruit is a tiny achene less than a millimeter long.[3]
The species is named for German-American botanist Wilhelm Nikolaus Suksdorf (1850-1932).[4]
