[摘要] Platismatia wheeleriwas recently described as a species distinct from the highly morphologically variablePlatismatia glauca . Previously,P. wheeleriwas known only from intermountain western North America in southern British Columbia, Idaho, Montana, Oregon and Washington. After examining collections from the New York Botanical Garden and Arizona State University herbaria we discovered thatP. wheeleriwas collected in southern California and the Tatra Mountains of Slovakia. The morphology, ecology and biogeography ofP. wheeleriare discussed, and the importance and utility of historical collections is highlighted. This article is intended to alert researchers to the potential presence ofP. wheeleriin different regions of the world so we can better understand its historical and current distribution and abundance.
