Observations on Virginia Plants. IV.

In this paper are notes, taxonomic or distributional on Xerophyllum, Impatiens, Oenothera, Melampyrum, Penstemon, Chelone, Veronica, and Taraxacum. They are largely based on collections made during the spring and summer of 1945 in Shenandoah National Park, in the Blue Ridge of Virginia. They may be considered preliminary to a second supplement to the checklist of plants of the park by Fosberg and Walker (Castanea 6: 89-1346, 1941). Nomenclatural combinations are proposed in Impatiens and Chelone. Specimens cited will be deposited in the U.S. National Arboretum (USNA) and the U.S. National Herbarium (US).
