Discussion | This rare old-forest obligate is readily distinguished by its purple-spotted, clawed tepals and its three-lobed, straw-colored, hairy-papillose fruit (R. G. Johnson 1968). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Recent collections have extended the known range of Prosartes lanuginosa from the unglaciated Appalachians to the other ancient, eastern North American upland, the Ozark Mountains of Arkansas. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
