|Faneng in winter|
Plant of singular appearance, which could be taken for a mushroom, the faneng is in fact the fleshy shoot of a large rhizome.
This toxic, very stringy bud bears at its apex a green puff called cladode which is used for photosynthesis. Only this upper part is used by Zoraïs (the faneng-hakka*, which they think is a host plant) who extract from it a particularly effective anti-toxin.
