Elatostema umbellatum var. majus is
a perennial herb, 20-40cm tall, that grows in damp places along
streams where mamushi, a kind of 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 short petioles and set green-white flowers in clusters.
In autumn, the stem tip's nodes swell up to make bulbils. Bloom
