buds, which grow from clefts on the opposite margins of the fronds; these expand and again produce buds from 
their sides while attached to the parent frond, hence many fronds are attached at right angles to one another. The 
fronds throw out one simple capillary root, or tuft of these, furnished at the apex with a calyptra. Flowers rare, 
very minute, enclosed in a bract. Stamens one to two, with didymous anthers. Utriculus with one to four seeds.

An extremely abundant European plant, found in various other parts of the globe, as in Australia and Tas-

Very like Z. minor, but the frond is rounded below, sometimes hemispherical. This is also a very common 
Huropean plant, and found in other parts of the world.
