Ecology & Habitat

Description

Treelike Clubmoss resembles a miniature coniferous tree. The scattered, branched stems are 12-30 cm high and arise from deep rhizomes. Stems and branches are densely clothed in 6-8 ranks of narrow, sharp-pointed leaves that are 2-5 mm long. The spores, each subtended by a broadly lance-shaped bract, or sporophyll, are 2-4 mm long and are borne in dense, cone-like, brownish, 2-4 cm long spikes located at the tips of erect branches.

Diagnostic Characteristics

In other members of the genus, the rhizome is located above or just beneath the surface of the ground. The appearance resembling a miniature evergreen tree is distinctive.

Habitat

This species is found in second-growth shrubby areas and dry woodlands at elevations ranging from 50 to 1,800 meters (Wagner Jr. and Beitel, 2020)
