The Dysosma veitchii belongs to Berberidaceae (the Barberry family). It is a perennial herb that is distributed in south-central China, from Guizhou to Sichuan and Yunnan provinces. It grows in moist forests in mountains and valleys, and is 20-60 cm tall. The rhizome spreads in a creeping manner, and two palmately lobed leaves are borne at the top of the stem. Around April, umbels emerge from the top of the stem, and 2 to 6 light red flowers bloom. The Chinese name for this plant is "川八角蓮" (chuan ba jiao lian).
