Description edit
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.[4]
Etymology edit
The earliest name given to the plaint was Crossostephium insulare, coined by Per Axel Rydberg in 1916.[5] In 1935, Philip Alexander Munz declared this to be a variety of Artemisia californica.[6] 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.[7] Hence Raven's new name, Artemisia nesiotica.[8]
