--><p><i>Arctostaphylos nortensis</i> occurs on upland peridodite soils in the interior mountains of Del Norte County, California, and adjacent Curry and Josephine counties, Oregon. It appears to be a distinct entity and well distributed in this limited region; it could be confused with hybrids between <i>A. canescens</i> and <i>A. viscida</i> that have been described from the interior portion of its range. In the protologue, Wells did not mention their glandular pubescence, clearly visible on the type specimen; this feature can be difficult to discern in some herbarium specimens. The region of northwestern California and adjacent southwestern Oregon needs more study, this taxon being one example.</p>
