Notes



Move to List 1B? Field surveys needed. Known in CA only from the Klamath Range. Very difficult to distinguish from S. asprella and S. glaucescens, especially in herbarium material; needs further study. See Clybele Columbiana: A Series of Studies in Botany, Chiefly North America 1(1):35-36 (1914) for original description.
