Rare, oldest Silurian fossil land plant Salopella sp.

Salopella is a form genus for small fossil plants of Late Silurian to Early Devonian age. The diagnostic characters are naked axes branching isotomously, terminating in fusiform sporangia. The sporangia are unbranched, but in at least the type species the axes seem to branch just under the sporangia. It differs from the similar form genus Tortilicaulis in that the sporangia do not have spirally arranged cells, and from other similar form genera such as Cooksonia, Uskiella and Tarrantia in the shape of the sporangia.
