Utricularia subulata - (image 1 of 2)
Taxonomy
Family: Lentibulariaceae
Habitat
Wet soil and very shallow water.
Associates
Distribution
Nova Scotia to FL along the coastal plain, west to AR and TX.
Morphology
Underground parts very delicate, rarely collected, with bladders 0.5 mm; aerial leaves, if present, linear, to 1 cm; flowering branches very slender, erect, 3-20 cm, with 1-10 flowers; bracts ovate or elliptic, 1-2 mm, peltate, attached at or below their middle; pedicels 4-15 mm; corolla often yellow, the lower lip usually 4-7 mm, with prominent palate and widely spreading lumb; spur about equaling the lip and appressed to its lower surface.
Notes
Flowers May to September
Wetland indicator: OBL
I photographed these flowers a few years ago in an open peatland in Southern NJ. Most Utricularia keys do not focus on floral characteristics so I made this identification based on trial and error looking at images of species within range. I recall looking for leaves at the time and could not find them. Apparently there is a very small-flowered white form that can sometimes occur with the typical form.
