Stephania japonica

Description

Slender climber, 2-10 m. Leaves with glabrous or crispately pu-berulous petioles 3-12 cm;

Distribution

Asia-Tropical: India present; Thailand (Thailand present), Japan present, N. & E. Australia present, Polynesia present, S. China present
Japan, S. China, Indochina, Thailand, India, throughout Malesia, N. & E. Australia, Polynesia.

Uses

In var. discolor the tuberous root is bitter and very poisonous due to its picrotoxin content. It is used medicinally for fever, diarrhoea, urinary dis-eases and stomach-ache. Crushed leaves in water form a slightly gelatinous mass which is applied to breast infections. Although reported to be poisonous to livestock in Australia (), feeding tests have proved negative ().

Notes

The very extensive synonymy of this spe-cies is the result of combining the synonyms quoted by DIELS for three species, which he recognized as distinct, viz. S. jorsteri (DC.) A. GRAY, S. hernandii-folia (WILLD.) WALP. and S. japonica (THUNB.) MIERS. The only differences between these taxa con-cern the presence or absence of a puberulous indu-mentum on the lower surfaces of the leaves and on the inflorescences, as indicated in the key below. The degree of hairiness varies considerably but the great majority of the specimens I have examined can be placed in one of these three taxa, which occupy dif-ferent but overlapping geographical areas. I there-fore consider 5. forsteri, S. hernandiifolia and S. ja-ponica to be no more than varieties of one wide-spread species.
For a detailed discussion on the types see FORMAN (1956).
The endocarp of S. japonica was described by DIELS as imperforate. It is, however, usually per-forate in all three varieties of this species.
