Streptopus amplexifolius (twistedstalk,clasping twistedstalk,claspleaf twistedstalk,white twisted-stalk, or watermelon berry) is a species of flowering plant in the family Liliaceae, native to North America, Europe and Asia.
It is a herbaceous perennial plant growing to 40–100 cm tall, with alternate, oblong-lanceolate leaves 5–14 cm long. The greenish-white flowers hang from axils on 1–2 cm thin kinked panicles, each flower with six white tepals, 9–15 mm long. The plants leaves completely encircle the stem, and the stems have a kink at each leaf axil giving the plants stem a "twisted" and wiry appearance. The plants grow in a creeping habit in moist, dense undergrowth.
Streptopus amplexifolius is widely distributed across North America (Greenland, northern United States including Alaska; and most of Canada including Yukon and Northwest Territories). The plant is most often found near shaded stream banks and in moist thickets of the montane and subalpine zones across most of North America. It is also found in central and southern Europe (from Spain to Ukraine and as far north as Germany and Poland) and in eastern Asia (Japan, Korea, Myanmar (Burma) and eastern Russia (Yakutia, Amur, Kamchatka, Sakhalin, Kuril Islands, Khabarovsk, Primorye)).
