Poikilohydric

Poikilohydric [ Botany ]	Dictionary of botanic terminology - index of names

Of a plant able to survive desiccation without damage and to resume growth soon after re-wetting.

The poikilohydric lifestyle:

Poikilohydry means that the organism relies directly on the environment for its water. As a result, the organism's water content tends to reach equilibrium with that of the environment. Poikilohydric organisms have no mechanisms to prevent desiccation: they desiccate, and remain dormant, when their environment dries out, but can rehydrate when water becomes available again. They usually absorb water directly through their body surface.
Poikilohydric organisms include some green algae, cyanobacteria (blue-green algae), lichens, and the bryophytes. A rare example of poikilohydric higher plant is Blossfeldia liliputiana
