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.

Plants from slender, sometimes matted rhizomes with variable internode lengths. Stems simple or occasionally branched, 1.5–4(–8) dm, glabrous, nodes sparsely pubescent-fringed. Leaves 5–10 × 2–4.5 cm; blade ovate-elliptic, base rounded, margins finely glandular-pubescent, apex acute to acuminate; peduncle: junction with pedicel not abrupt, entire structure (5–)9–20 mm, glands absent or obscure. Flowers 1(–2) per axil; perianth campanulate; tepals slightly spreading but not recurved, white or greenish yellow, streaked or spotted with pale rose to reddish purple, narrowly oblong-lanceolate, 6–10 mm; stamens 5–8 mm; anthers 2 mm, apex 2-pointed; style slender, 3.5–4 mm; stigma weakly 3-lobed; combined peduncles and pedicels recurved, (5–)9–20 mm, glands absent or obscure; pedicel rarely geniculate at junction with peduncle, coarsely pubescent. Berries reddish purple to red, subglobose, 6–9 mm. Seeds 2.5–3 mm. 2n = 16, 48.

由wikipedia EN提供
Streptopus lanceolatus (rose twisted stalk, rosybells, rose mandarin, scootberry, liverberry, rose-bellwort), is an understory perennial plant native to the forests of North America, from Alaska to Labrador, south through the Great Lakes and Appalachian Mountain regions of the United States, as well as Montana, Washington state, Oregon, and St. Pierre & Miquelon.[2][3] It grows primarily in mixed-wood forests, and throughout a wide range of soil and site conditions, preferring cool, acidic soils.
Streptopus lanceolatus grows from a rhizome or seed, the stem having a zigzag shape, branched or sometimes unbranched. Up to 30 cm (12 in) tall with alternate wide lanced oval-shaped leaves with pointed tips and a rounded base, without leaf-stalks. The leaves are often finely toothed having fine hairs on the underside veins. Flowers appear as solitary individuals opposite each leaf in early summer (May to July) and are bell-shaped on 1–3 cm (0.4–1.2 in) long stalks bent midway, with 6 rose or white recurved petals with purple streaks. Fruit is an elongated red berry ripening in mid-summer (July to August). If berries are consumed in quantity, diarrhea can result.[2][4][5]
Streptopus lanceolatus can be distinguished from Solomon's seal and false Solomon's seal by the alternate leaves on a zigzag stem.
