Habitat
Forests, swamps
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.

3. Goodyera repens (L.) R. Br. in Ait. & Ait. f. N
dwarf rattlesnake-plantain. Goodyera ophioides (Fern.) Rydb.; G. repens (L.) R. Br. in Ait. & Ait. f. var. ophioides Fern.; Peramium ophioides (Fern.) Rydb.; Satyrium repens L. • CT, MA, ME, NH, VT. Evergreen and mixed evergreen-deciduous forests, usually growing on humus-rich soil and/or with bryophytes.
Native to North America?
Yes
Sometimes confused with
- Goodyera pubescens:
- spike cylindric, equally dense on all sides, the spiral of flowers hardly discernible, and scape with 4–14 bracts (vs. G. repens, with the spike less dense, with secund flowers, and scape with 2-7 bracts).
- Goodyera tesselata:
- flowers spirally arranged, leaf blades with 5-9 nerves, and sac-like portion of lower petal (the labellum) longer than deep (vs. G. repens, with flowers usually arranged in a one-sided array, leaf blades with usually 5 nerves, and sac-like portion of lower petal (the labellum) as deep as wide).
