Selaginella apoda — meadow spikemoss
Copyright: various copyright holders. To reuse an image, please click it to see who you will need to contact.
Facts
The stems of meadow spikemoss have two rows of larger leaves and two rows of smaller leaves. The veins in those leaves help distinguish it from a true moss.
Habitat
Anthropogenic (man-made or disturbed habitats), meadows and fields, riverine (in rivers or streams), shores of rivers or lakes
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.

1. Selaginella apoda (L.) C. Morren N
meadow spikemoss. Lycopodioides apoda (L.) Kuntze • CT, MA, ME, NH, RI, VT; nearly throughout but absent from most of ME and northern NH. Stream banks, mesic to wet-mesic meadows and lawns.
Native to North America?
Yes
Sometimes confused with
- Selaginella eclipes:
- median trophophylls with a long-attenuate, often recurved, apex, not keeled, the vein prolonged into the tip, and megaspores 0.33–0.4 mm in diameter, more loosely reticulate, shiny (vs. S. apoda, with median trophophylls acute to acuminate at apex, rarely attenuate and then often apically keeled and the vein not reaching tip, and megaspores mostly 0.29–0.35 mm in diameter, closely reticulate, dull).
