Gratiola virginiana
Some plants from tidal wetlands in Maryland, New Jersey, and Virginia are purportedly relatively shorter in stature and bear shorter pedicels and smaller capsules than most plants of Gratiola virginiana. They have been treated as var. aestuariorum; the distinctness of var. aestuariorum has not been assessed in the context of morphological variation across the range of G. virginiana.
