Common or Greater Bladderwort |
Utricularia vulgaris |
Bladderwort Family - Lentibulariaceae |
This free-floating herb has no roots. What appear to be roots are really extremely
finely divided leaves about 2 to 3 inches long, in this case encased in mud at
the edge of a marsh. Among the leaf divisions are a number of small bladders
that the plant uses to capture tiny aquatic organisms utilized as food. |
The leafless flower stalk rises 2 to 3 inches above the water and bears a small group
of bright yellow flowers (0.5 to 0.75 inches long). The snapdragon-like flowers
have two lips of about equal length with the lower one having a spur shorter
than the lower lip. (Photographed - July) |
