Spiranthes lucida — shining ladies'-tresses
Copyright: various copyright holders. To reuse an image, please click it to see who you will need to contact.
Facts
Shining ladies'-tresses is found in all New England states on river and lake shores, seeps and meadows, especially on high-pH sites. This species differs from the other New England members of its genus (Spiranthes), in having flower morphology more adapted to the small, short-tongued bees in the sweat bee family (Halictidae), whereas the other species are morphologically adapted to the larger long-tongued bees, such as bumblebees (Bombus) and leaf cutting bees (Megachilide).
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.
