Aquatic plant found in shallow, muddy pools in forest bogs, often creeping in the mud as in the plant above. Yellow flowers in early July, flowers with a large, flat lower lip (in above photo was 14 mm across). Flowering scape was 11 cm long. Leaves are divided several times into thread like segments. Carnivorous plant which captures its prey via tiny bladders submerged underwater.
Distinguishing characteristic of this species is that the bladders are not intermixed among the leaves, but are found rather on their own branches without leaves.
Found occasionally in bogs.
Small bladders, approx 3 mm in diameter. From the book Carnivorous Plants by Randall Schwartz:
The bladder, or trap, is an oval balloon with a double-sealed, airtight door on one end. When the door is closed, the bladder expels water through its walls, creating a partial vacuum inside.
Jutting out near the door is the trigger. Sometimes forked or branched, sometimes single, the device is always deadly. The instant an unsuspecting prey touches the trigger, the door opens. The vacuum inside causes an immediate suction and the victim is gulped up by the plant.
The above photos were taken in acidic bogs in June 29th and July 20th in boreal forest in central Saskatchewan.
