Discussion
Ranunculus canus var. ludovicianus is endemic to the Transverse Ranges of California. Pending further study, I am reluctantly following L. D. Benson's (1948) placement of this taxon. The plants have the floral characters of R. californicus and have often been included in that species. Indeed, forms of R. californicus from the foothills west of the San Joaquin Valley may also have large achenes with deltate beaks. Those plants differ from R. canus var. ludovicianus only in their ovate leaf segments. Further study of the group is much needed.
