A. A. Reznicek
Marshy ground, conifer thickets; especially characteristic of recently exposed calcareous shores and bottoms, interdunal hollows, and ditches.
Typically forms dense ± prostrate tangled mats (though other species may do the same if growing on open sites without vegetation to support them). The very small pedicels (usually ± recurved), fruits, corollas, and leaves, if all are displayed, are distinctive.
