Artemisia nesiotica is a rare California species of sagebrush in the daisy family, known by the common name island sagebrush. It is endemic to the Channel Islands of California, found on 3 of the 8 islands (San Nicolas, San Clemente, and Santa Barbara Islands).[2]
Artemisia nesiotica is a small shrub growing up to about 50 cm (20 inches) tall and generally rounded in shape. It produces several thin, upright stems from a woody base. The foliage is made up of woolly leaves divided into many thin, flat, threadlike segments. The inflorescence is a narrow cluster of several flower heads. The fruit is a tiny resinous achene with a pappus of hairs.[3]
The earliest name given to the plaint was Crossostephium insulare, coined by Per Axel Rydberg in 1916.[4] In 1935, Philip Alexander Munz declared this to be a variety of Artemisia californica.[5] Peter Raven later wanted to recognize the Channel Island plants as a distinct species within Artemisia, but the name Artemisia insularis had already been used for a Kuril Islands plant in 1936.[6] Hence Raven's new name, Artemisia nesiotica.[7]
