Lycopodiella Holub. Bog-Clubmoss.

Key to Lycopodiella

A genus of about 15-20 species, temperate and tropical. Additional research on this genus in our area is needed. Two fertile tetraploid species were named from MI (Bruce, Wagner, & Beitel 1991), and additional cryptic or semicryptic species may be found in the Southeastern Coastal Plain. This group has been variously treated as genus Lycopodiella, or as Lycopodiella section Lycopodiella (Øllgaard in Kramer & Green 1990, Wikström & Kenrick 2000), with a strong trend towards generic rank.

ID notes:Species of this genus are difficult to identify. They often grow together; it is not uncommon to find two or more species at a single site in the southeastern Coastal Plain. Hybrids occur. Juvenile plants, resprouting in spring or after fire, are especially difficult to identify. In contrast to most Lycopodiella species, Pseudolycopodiella caroliniana and, to a lesser degree, Lycopodiella prostrata, are dorsiventrally flattened (or "pseudodistichous"), but it seems that juvenile sprouts of all species are somewhat flattened.
