Discussion

Clarkia lewisii is known primarily from Monterey County, sparsely in San Benito County, barely reaching Santa Clara County, and is listed as rare by the California Native Plant Society. It is most closely related and morphologically similar to C. cylindrica, from which it can be distinguished by having all filaments about equally wide and a ring of hairs at the rim of the floral tube; outer filaments of C. cylindrica are two times as wide as the inner ones, and the ring of hairs is within the tube below the rim. Clarkia lewisii is also closely related to C. rostrata, from which it differs conspic­uously by having a much shorter capsule beak.

Clarkia lewisii is a new name applied to the species known until 1978 as C. bottae, following examination and reinterpretation of the type of Godetia bottae Spach by P. H. Raven and D. R. Parnell (1978). They determined that the type specimens of G. bottae actually referred to the species then known as C. deflexa (Jepson) H. Lewis & M. E. Lewis, and reapplied the name C. bottae to that species in sect. Fibula.
