Discussion

Kopsiopsis hookeri is a coastal species parasitic on Gaultheria shallon (Ericaceae) and confined to the range of the host species. It has been reported rarely on Alnus, Arbutus, and Arctostaphylos. Reports on Pinus are clearly spurious. It is often confused with K. strobilacea because of their close morphological similarity, but K. hookeri is a much smaller plant.

The range of Kopsiopsis hookeri is from southern Oregon and northwestern California to the Queen Charlotte Islands (Haida Gwaii) in British Columbia, with apparently disjunct populations in isolated locations in California. A few historic collections at CAS and UC from southern California are morphologically indistinguishable from typical K. hookeri, indicating that this taxon may have once occurred south of its present distributional boundary. Populations represented by specimen records from Marin (1925, 1944, 1958), Mendocino (1966), and Monterey (1957) counties may still be extant and indicate the need for additional studies to determine the current range of the species. A single specimen from Los Angeles County may be mislabeled, as this area is outside the range of the host taxon.

No morphological evidence was observed in the disjunct populations to suggest genetic influence from Kopsiopsis strobilacea; refer to 1. K. strobilacea for further discussion.
