Kopsiopsis
Kopsiopsis hookeri
Species 2 (2 in the flora).
Kopsiopsis was first recognized by Beck but was treated as part of Boschniakia by many subsequent authors. Zhang Zhi Y. (1987) and Yu W. B. (2013) presented further morphological evidence for separating the two genera. Kopsiopsis differs from Boschniakia in the following traits: inflorescences compact or open racemes versus dense spikes; pedicels present versus absent; bracteoles present (rarely absent) versus absent; corollas funnelform versus short-tubular, constricted above ovary versus corolla base inflated; leaves spatulate versus triangular or lanceolate; and, seeds 1.5–3 mm versus 0.5–0.7 mm. Molecular phylogenetic analysis of the family (J. R. McNeal et al. 2013) supports Boschniakia as sister to a lineage that includes the genera Conopholis, Epifagus, and Kopsiopsis, and as-yet unpublished molecular data suggest that Kopsiopsis may be sister to the southern Mexican genus Eremitilla Yatskievych & J. L. Contreras (S. Mathews, pers. comm.).

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.
