Introducing Lycopodiella diffusa and Lycopodiella lateralis


Lycopodiella diffusa is low-growing, with short branches. It occurs along the west coast of the South Island (including Southland), and into Stewart Island. In the North Island, it is scattered in upland areas.


Lycopodiella lateralis grows upright, with longer branches. It is relatively common in the northern North Island and the north-western South Island, while being scattered in the southern North Island and west coast of the South Island.

Open, swampy (or otherwise wet) areas are typical habitat for both species. Lycopodiella diffusa is more in cold habitats; L. lateralis in warmer habitats.

Both might be confused with other plants, but the little ‘cones’ where the spores are produced are distinctive.

Lycopodiella diffusa and L. lateralis - are they different?

The lycophytes Lycopodiella diffusa and Lycopodiella lateralis are sometimes easy to distinguish and sometimes not! We want to determine if they really are distinct species. Pat Brownsey is just beginning to draft the eFloraNZ treatment for the Lycopodiaceae.

You can help us - please add photos to NatureWatchNZ if you see Lycopodiella diffusa or L. lateralis (or something in between).
