Abstract

Hemiparasitic Scrophulariaceae generally exhibit a wide host range. However, species of Aureolaria, a genus endemic to North America, have been thought to be host-specific on subgenera of Quercus L. Aureolaria pedicularia plants from Virginia and South Carolina were excavated and the hosts identified to family by the morphology of the root segments. Most haustoria were found to be attached to Fagaceae, but a few were on Ericaceae. It is suggested that for A. pedicularia there exists a physiological preference for Fagaceae, although not an absolute host specificity.
