Discussion | Pedicularis howellii is found in the Siskiyou Mountains along the California/Oregon border; it has undivided distal leaves. The division of the proximal leaves into irregular and asymmetric lobes, sometimes appearing auricled, is a unique feature of this species.

Discovered in 1880, and at one time believed extinct, Pedicularis furbishiae was rediscovered in 1974 during an environmental impact survey for a proposed dam on the St. John's River and thereafter was placed on the Federal Register under the Endangered Species Act (L. W. Macior 1981). Metapopulation dynamics suggest that an ecologically intact watershed is required for long-term persistence (E. S. Menges 1990). A recovery strategy has been adopted for this species in New Brunswick (Furbish's Lousewort Recovery Team 2006; Environment Canada 2010). Pedicularis furbishiae is in the Center for Plant Conservation’s National Collection of Endangered Plants. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
