Abstract

Erigeron pacalis Björk (Asteraceae) is a new species found only in the Peace River Grasslands of northeastern British Columbia, Canada. Its characteristics (short stature, leathery leaves, vestiture of mixed glandular and nonglandular hairs, and white rays) distinguish it from E. glabellus Nutt. and E. asper Nutt., the latter of which has appeared only in synonymy under E. glabellus according to most recent authors, but which shows consistent distinctions that merit its resurrection from synonymy.
