Webelaters are proposed for the elaters of two positions, that is, cluster-forming and free. In addition to free elaters, which are well known as spore dispersal organs of Hepaticae, a cluster of fixed elaters is formed in the capsule by some Hepaticae.

An elater is a cell (or structure attached to a cell) that is hygroscopic, and therefore will change shape in response to changes in moisture in the environment.
