EElatostema umbellatum var. majus is a perennial herb, 20-40cm tall, that grows in damp places along streams where mamushi, a pit viper, is likely to appear. Stems are succulent, with no hairs. Leaves are deformed, long, oblong, 4-10cm long, with tips extending in a tail way, coarse serrations on margins, and coarse hairs on upper and lower surfaces. Axils emerge with short petioles and set green-white flowers in clusters. In autumn, the nodes at the stem tip swell to form bulbils. Bloom time: April-September.
