Discussion

As reflected in the synonymy, Hypericum anagalloides is variable; none of the variations merits taxonomic recognition.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Hypericum canariense is established at Montecito and Santa Barbara in the hills (P. A. Munz 1974) and along the coast north of Santa Cruz to San Francisco, at locations in Orange and San Mateo counties, and in the San Diego coast region.

The description above agrees with that for Hypericum floribundum regarding sepals lanceolate and acute; in typical H. canariense they are oblong-spatulate and rounded. The variation is continuous; only one species is recognized here.
