Streptopus lanceolatus
Streptopus lanceolatus has replaced the long-used name S. roseus, based on the recent lectotypification (J. L. Reveal 1993d) of Aiton’s Uvularia lanceolata. This widespread North American species has been divided into four intergrading varieties or races (N. C. Fassett 1935) based on variation in rhizome internode lengths and density of leaf-margin ciliation. These include var. roseus in the southern Appalachians, var. longipes in the western Great Lakes region, var. lanceolatus (= var. perspectus Fassett) in the northeast, and var. curvipes in the west.
