Utricularia vulgaris L., common bladderwort or greater bladderwort
Family: Lentibulariaceae
Bladderworts are carnivorous plants with delicate, finely-divided underwater leaves and emergent snapdragon-like yellow flowers. The most distinctive underwater features are the small bladder-like traps. These traps use a vacuum to capture small invertebrates or even tiny fish that trigger the trap door. Enzymes are secreted to digest the prey which provides the plant with nutrients. Several bladderwort species are found in Washington.
Leaf: No true leaves. Instead both species have green, highly branched, finely divided underwater leaf-like stems with small seed-like bladders. Bladderwort plants often appear dense and bushy underwater. Swollen bladderwort has a distinctive spoke-like whorl of 4 to 10 wedge-shaped floating leaves, 4 to 9 cm long, which supports the flower stalk. Stem: The branched stem is up to 2 m long and can be floating, submersed, or partly creeping on the sediment, sometimes anchored at the base by root-like structures. Flower: Yellow, snapdragon-like flowers occur above the water. Swollen bladderwort: flowers to 20 mm wide, in groups of 3 to 14 on upright stalks supported by a spoke-like float. Flowers in spring in Washington. Common bladderwort: flowers to 25 mm wide on stout stalks, with a prominent spur projecting below the lower lip of the flower. Flowers often have faint purple-brown stripes. Flowers in late summer. Fruit: Capsule contains many seeds. Swollen bladderwort: fruit stalk (pedicel) to 35 mm long. Common bladderwort: fruit stalk (pedicel) to 20 mm long. Root: None.Propagation: Fragments, seeds. Swollen bladderwort: may form tiny tubers, small coiled winterbuds. Common bladderwort: may form very large (4-5 cm across) bright green winterbuds. Importance of plant: Food and cover for fish. Food for muskrats and waterfowl. Habitat for aquatic invertebrates. Swollen bladderwort: can become invasive.Distribution: Swollen bladderwort: principally in eastern North America, but introduced and increasingly present west of the Cascades. Common bladderwort: throughout the northern hemisphere.Habitat: Floating freely in shallow water, or loosely attached to the sediment.

Una gran imagen así como gran idea de capturar esta planta carnívora y además acuática Didier.
Me encanta la composición del espécimen que se asemeja a un árbol con sus ramas libres de hojas y sobre el agua que con un contrastante color y difusión para resaltar la silueta de la misma.
Imaginativa y estética presentación.
Gracias y hasta la próxima.

Great image as well as great idea of capturing this carnivorous and also aquatic plant Didier.
I love the composition of the specimen that resembles each other to a tree with their branches free of leaves and on the water that with a contrasting color and diffusion to stand out the silhouette of the same one.
Imaginative and aesthetic presentation.
Thank you and until the next one.
Ricardo

Hi Didier

First I need to congratulate you on the very articulate and informative notes. I don’t know much about this subject, but you painted a very clear picture.

Definitively this is no easy subject to photograph. The water would obviously reflect the least bit of light coming in on an angle, like it has done on the top right-hand corner, but you did very well to contain it in that area where it did not much affected the plant. The wide DOF caught great details on the plant and the bladder-like traps.

Very well done and TFS.
Regards
Loot

PS. May 2007 bring all the joy & happiness, good health & strength, and prosperity & fortune to you and your loved ones. And of course some good light on your photographs.

I agree with Krzysztof (cataclysta)
Good note and compo..

Nice framing and good idea..

Best regards,
Sandu
