Patterns of vascular plant endemism in the southern Klamath Ranges of northwestern California.

THE Southern Klamath Ranges encompass several well-known mountain ranges—the Trinity Alps and Eddys, in particular—as well as lesser-known landscapes. The geographic area selected for analysis is bounded on the north by the Trinity Alps, the west by South Fork Mountain, the south by the Yolla Bolly Wilderness, and the east by Lake Britton, and includes parts of Trinity, Shasta, and Siskiyou Counties. Vascular plant endemism studies of this area have focused on serpentine endemics of the Trinity Ultramafic Sheet, which underlies the Eddys, Scott Mountain, Trinity Mountains, and the eastern edge of the Trinity Alps in northern Trinity and southern Siskiyou Counties; and the drier, more patchy serpentines of the Rattlesnake Creek Terrane to the south and west of the Trinity Ultramafic Sheet. However, other distinctive endemism patterns, not necessarily related to ultramafic substrates, are present in the Southern Klamath Ranges. The mild, moist, ancient Eastern Klamath Range landscape is home to several strict geographic endemics, including Shasta snow-wreath (Neviusia cliftonii). Disjunctions from the Trinity/Scott Mountains to the southern Sierra Nevada and Transverse Ranges of Southern California are also noteworthy.
