BLADDERWORT FAMILY
Reading edition
Bladderwort Utricularia vulgaris
Plate 22, fig. 5
The yellow flowers of the Bladderwort grow on erect branches from submerged stems 1-4 ft. long, and are found in lakes, ponds, etc. at 3000-12000 ft. The Bladderwort receives its name from the tiny black bladders which grow on the submerged, finely divided leaves. These little bladders serve as traps and absorptive organs for tiny animals in the water, and the plants thus live partly on insects, larvae, etc.
