Abstract
The current taxonomic treatment of Epilobium sect. Zauschneria includes two species, Epilobium canum (Greene) P.H. Raven and Epilobium septentrionale (Keck) Bowman & Hoch.
Both species are fall-flowering woody perennials restricted to western North America. Epilobium septentrionale is a narrow northern-California endemic, restricted to rocky crevices along the Eel, Mattole, and Trinity River drainages.
The polytypic species, E. canum, is divided into three subspecies; canum, latifolium, and garrettii.
Epilobium canum subsp. canum encompasses all of the varied forms of the California coastline and the Central Valley from Clear Lake to Baja California. Epilobium canum subsp. latifolium is primarily restricted to the inland Cascade Range of extreme southwestern Oregon and the Sierra Nevada of eastern California. Epilobium canum subsp. garrettii is separated from its western relatives by the vast Great Basin.
It occupies rocky crevices and cliffs of western Wyoming and northern Utah (Bowman, 1980).
