Stopped at Abner's Pond this morning before heading home from camp, since I hadn't been down there during the day in a bit. Spotted these funky-looking flowers, no idea of the type (a little digging around on Google makes me think these are some sort of bladderwort) growing along the beach, so I got down low to get a few pictures with the pond as background.

Purple Bladderwort is a lovely flower which actually is an insectivorous (insect eating) aquatic herb. The beautiful petals hide the true nature of the flower from the insects very well. Photographed on Kaas Plateau near Satara in India.

This shows the Lesser Bladderwort Utricularia minor flower in it's wider perspective on a Sphagnum bed. It's for those who don't are not familiar with the flower, and who may not know just how small it is. I got a bit wet getting the photos. I had to lie on wet peat and partly on the Sphagnum, pushing the lens through Cotton Grass and Molinia stems, bending them out of the way.
Lesser Bladderwort is an unusual carnivorous plant, which is quite uncommon, and this is why I thought people might be interested in it. It's probably often overlooked, because often it doesn't flower, and the flowers are tiny, with most of the plant being below the surface.

Bladderwort (Utricularia moniliformis). This small and delicate carnivorous plant is endemic to the mountains of central Sri Lanka. It grows among clumps of moss either as an epiphyte or adjacent to rocky streams. Horton Plains National Park, Sri Lanka.

Utricularia menziesii is a carnivorous plant endemic to south western Australia. This eye-catching plant is usual in many ways: it is one of only 4 red-flowered species in the genus (of about 220 species); it is pollinated by birds; and is a seasonal perennial that dies down to tubers each summer. The flowers last at least a month. Thus there is plenty of time to enjoy the flowers in cultivation.
With over 200 species Bladderwort is the common name given to the largest genus of carnivorous plants, genus Utricularia. They are found in fresh water and wet soils across all continents other than Antarctica. I found it hard trying to get information on this plant and trying to identify this species but here is a quote I found on the Internet:-
"Bladderworts possess the most complicated and devious trap of all the carnivorous plants, and is surely one of the wonders of the botanical world.
The carnivorous action happens underground, in the water-soaked medium. Each plant produces a great number of bladders, a few to several mm in size, which serve as the mouths of the plant. These bladders have trap doors, and when a free-swimming organism bumps into long hairlike organs attached to the trap doors, the hairlike organs lever the door ajar. The water pressure inside the bladder is lower than the surrounding water, so the partial vacuum instantly sucks the organism inside the trap. The prey has no chance to escape, since it is drawn into the trap in as little as 1/30 of a second. The trapdoor resets and the plant begins digesting the creature."
The one I have here was in the swamp land in the Daintree River close to the Ferry crossing. I think my species may be this one:-

Utricularia purpurea, Jackson County Wisconsin, 30 July 2019.
Utricularia reniformis (Lentibulariaceae) a bladderwort, University of Oxford Botanic Garden. Bladderworts are carnivorous: rather wonderfully, they capture animals in their bladders.

The carnivorous plants depicted in these photos represent a newly discovered site for these species in Georgia. the Sarracenia psittacina of these bogs are among the largest I have ever seen. It is apparent that S psittacina in highly aquatice habitats allow for giant plant development as seen in Okeefenokee swamp and on Eglin AFB.
This variant has now been published as Sarracenia psittacina var. okeefenokeensis based on morphometric characters that appear to be genetically derived. Based on my field observationsof these plants in three distinct habitats throughout the southeast, i agree with this assessment. see McPherson & Schnell, Sarraceniaceae of North America, Redfern 2012.
Bladderwort with yellow flowers, sundew (bottom center), and pitcher plants are three varieties of carnivorous plants that thrive on this small island on a cataract bog in nothern Greenville County.
The Eva Chandler Heritage Preserve is site of this rare cataract bog. A continual flow of water forms pits in a granite outcropping. Soil in the pits forms islands, where an assortment of exotic plants take root. This is a perfect environment for carnivorous plants. The low level of nutrients in the soil keeps out competing plants, and these plants are able to get nutrition from the insects they consume.
Purple Bladderwort (Utricularia purpurea). Deep East Texas.
Utricularia purpurea is an aquatic, carnivorous plant that inhabits much of the Eastern United States. It barely enters Texas in the extreme southeast portion of the state, where it is rare.
Utricularia purpurea was one of my 2017 biodiversity goals. To read more about these goals and my pursuit of this species check out my blog by clicking here.

Comment: Utricularia minor is a very interesting carnivorous aquatic plant. It grows in standing and very slowly flowing waters. Only its flower stalks with yellow, bizarre looking flowers, resembling gluttonous mouth, rise above water surface. Long stolons and stalks with several times divided leaves having thin final segments live in water. The plant catches and digests small water animals like water fleas, nematodes, small fish fry and mosquito larvae with bladder-like traps situated on their leaves. Hundreds of these traps can be found on a single plant. Each bladder, which was initially thought to be a flotation device before its carnivorous nature was discovered, has a small mouth, 'trap door', surrounded by several branched protuberances looking like some kind of tentacles.
The functioning of these traps is ingenious – many agree the most sophisticated and simple at the same time carnivorous trapping mechanism to be found within plant kingdom. The bladder is a purely mechanical device without any sensory functions. The only active mechanism involved is the constant pumping of water out of the bladder through thin bladder's walls by cellular transportation mechanism. Since the mouth (trap door) is normally tightly closed, this pumping crates negative pressure within the bladder and squeezes it somewhat. The 'tentacles' are stiff and attached to the flexible mouth lip. If an animal touches these 'tentacles' they work simply as mechanical levers and deform the mouth lip a bit. The mouth loses its tightness and, because of the negative pressure inside the bladder, water instantly brakes into the bladder – together with the pray. This happens in about 10 ms only! The mouth closes and the pray is slowly digested by the plant. After the meal is finished the whole process starts again (Ref.: 4). Note: Picture of the bladder taken through a microscope shows similar bladder of Utricularia intermedia and not of Utricularia minor!
Utricularia minor is widely distributed all over the world (except Antarctica). In Slovenia it is rare, highly endangered and protected by law as all other four species of this interesting genus present in the country.
