What is "adenostoma"

Adenostoma is a genus of shrubs containing only two species:

• Adenostoma fasciculatum — Chamise
• Adenostoma sparsifolium — Red shank.

Both species are native to coastal California and Baja California. Adenostoma fasciculatum is also native to California in the Sierra Nevada. They are found in plant communities and sub-ecoregions of the California chaparral and woodlands ecoregion.

Both species in this genus feature stiff, linear leaves arranged alternately or in clusters along stems with shredding bark. Flowers form on a panicle, are cream to white and, as in all members of the rose family, have hypanthia.
