Cryptantha of California (Kelley et al. 2012. The Jepson eFlora)

Johnston 1925 Description
From Johnston 1925, p. 92: "This is a very well marked coastal species, but has been greatly misinterpreted in the past and at various times made to include nearly all the smooth-fruited species of the genus. Study of material in the Gray Herbarium which was raised from authentic seeds received from St. Petersburg, Hamburg and Geneva, shows clearly that the name should be applied to the sea-shore plant of middle and northern California which has bracteate spikes, long styles, and small ovate smooth nutlets with a simple or barely forked groove. Occasionally it grows with C. hispidissima and has been confused with that species, although it is readily separable from it by its bracteate spikes, shorter ovate nutlets, simple or barely forked groove, and commonly smaller corollas. The leaves are usually 1-3 mm. broad, but in some peculiar forms from Surf, Santa Barbara County, California, which apparently grew with the common form, the leaves are broadly oblong, retuse and nearly 10 mm. broad."
