Sponge-plant

Sponge-plants are flowering plants native to Spiridon.

When a sponge-plant senses nearby animals, it shoots out a liquid containing fungal spores which will attach to and spread on those who are hit.

Jo Grant was infected by a Sponge-planet. A Spiridon applied a paste to the infection, curing her.(DW: Planet of the Daleks)

Behind the Scenes

 * The sponge-plant is not named on television, only in the novelisation.
 * It is never made clear whether the sponge-plant and the fungal spores are two separate species in a symbiotic bond or one species with qualities of both plant and fungus. In nature, a flowering plant reproduces by producing seeds.
