Dioscoraceae
Dioscorea esculenta   (Lour.) Burkill
(Yanm) kouchkouch blan. Potato yam. Topi tanbou. Yanm glo cho.
Native to tropical Asia
The potato yam is smooth skinned and white inside. The stem is very spiny. 10cm leaf. We found a different variety at Au Leon which the farmers call topi tanbou. It is not the real topi tanbou  Another thicker-skinned variety was found in Mon Repos - it is called yanm glo cho - it is so quickly-cooked it is placed in boiling water and the heat turned off.
