Sundew (Drosera auriculata)
I went back to look for the Sundew today and not only were they still doing well, they were soaked with raindrops from the big rains we’ve had in the last few days. They're very small and would easily be missed by most, but I knew where a clump of them was growing. Sundew are carnivorous plants that derive some or most of their nutrients by trapping and consuming animals such as insects or other arthropods. In New Zealand we have Drosera (sundews) - seven native species - and Utricularia (bladderworts) - three native species ❤️
Utricularia minor (Kleine Wasserschlauch) , Dorset
Looking unsuccessfully for Bog orchids but finding lots of Sundews (Oblong leaved Sundew here in the photo) and many small Lesser bladderwort plants. None taller than 6-8cm
Utricularia cornuta
Bladderworts are carnviorous plants. They get nutrients from small organisms captured in bladders on the leaves. Some bladderworts float on water and feed on tiny aquatic animals. However, horned bladderwort grows on fens and bogs, its leaves penetrating the mud to trap soil organisms.
Each bladder has a trigger hair. When something brushes it, a trapdoor opens and sucks the prey inside to be digested.
Horned bladderwort shares habitat with other carnivorous plants including aquatic bladderworts, purple pitcher plant, and round-leaved sundew, which captures insects on its sticky leaves. This carnivorous strategy is common in bogs because water leaches nutrients out of the soil. If you can't draw vital nutrition from the soil, you can try to catch whatever flies or swims past.
Because horned bladderwort lacks roots and has inconspicuous leaves, it is hard to detect when not in bloom. The flower's shape prevents water from splashing the pollen, reserving it for pollinators.
Thank you to everyone who visits, faves, and comments.
Utricularia foliosa from Brazoria County, Texas. U. foliosa has a broad range that includes parts of North America, South America, and Africa. It is apparently native to the U.S., where it occurs in the coastal plain from Florida to Texas. This individual is from a population in a freshwater wetland along the upper Texas coast.

Water levels even in bogs are very low now with the long heat and draught and only very few Lesser bladderwort are to be seen
Lakes and rivers impacted by acidic precipitation become devoid of fish and sometimes get very clear, transparent water.
In this small lake on the southern coast of Norway, dead birch leaves float over beds of submersed peat moss Sphagnum cuspidatum, interspersed with bladderwort Utricularia minor. Water transparency was out of this world, like floating suspended in air. However, the impression of beauty hides a dead lake where all fish have gone years ago.
A little known feature of the Nikonos V allowed me to take this long-exposure underwater scene. Set the 'A' mode, the camera would keep the shutter open for a long time under low light levels. I attached the camera to my modified underwater tripod and did my best to lay completely still in the ice-cold autumn lake. Not my easiest challenge, admittedly, but I did get the capture I had hoped for, in part helped by the very calm weather that day.

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.
Floating bladderwort is a carnivorous freshwater aquatic plant. Seven radially arranged stolons act like tiny pontoons to float at the surface of the water.
The tiny bladders (small hollow sacs) below the surface actively capture and digest tiny animals such as insect larvae, aquatic worms, and water fleas.

The Green House of the Utrecht University Botanic Gardens has a nice collection of carnivorous plants. I was lucky on my visit to see this Brazilian Bladderwort, Utricularia reniformis, in beautiful flower. It was discovered in Brazil by that indefatigable botanist and traveler, and moreover fine author Augustin François César Prouvençal de Saint-Hilaire (1779-1853). This afternoon I had some time to read in the account of his voyage to Brazil in 1830, in which he waxes eloquent on every aspect of his trip. Lots of anecdotes and observations about places and people and history and even anthropology, and all of this is laced with enthusiasm for the plants which he sees (and collected). This Bladderwort is one of his discoveries.
The Big Cypress National Preserve. Florida. USA.
The Florida Bluet (Enallagma pollutum) is an American damselfly whose range is restricted almost entirely to the State of Florida in the US. Their habitat is ponds, lakes, slow streams, and canals. I found this Florida Bluet perched on Common bladderwort (Utricularia macrorhiza) in the Big Cypress Swamp.
At 2500m elevation. This is the typical ecological occurrence for this species in the guiana shield region.
Just a few things currently going on in my front yard bog garden.
This red form of the Threadleaf Sundew happens to have white flowers, unlike many of the pink-flowered ones found in the Florida panhandle.
Deep East Texas.
This is not a safe place for aquatic invertebrates. Pictured here is a seasonal pond within a longleaf pine savannah that was filled with thousands of Floating Bladderworts (Utricularia radiata). These carnivorous plants have submerged leaves that contain air-filled sacs set with a small hairlike trigger. When an aquatic invertebrate brushes up against the trigger the sac opens and pulls it in to be slowly digested by the bladderwort.
Cowan's mantella is one of the most imperiled amphibian species in Madagascar. It is restricted to microhabitats heavily encroached by farming and other local agriculture. Protection of this species and its habitat relies on local community leaders who routinely monitor the habitats and facilitate outside research visits.
This specific microhabitat was comprised of low nutrient seepage slope which was populated by several species of carnivorous plants and orchids. Truly a very fragile habitat which likely cannot be recreated if damaged or destroyed.
Had a lovely walk through Fish Creek Provincial Park in Calgary today, and saw some unique wildflowers. The Hemlock is said to be highly poisonous. The Scentless Camomile, while pretty, is a much-hated invasive weed. We don't have a lot of water plants in Calgary, and so it was nice to see the Common Bladderwort. Smooth Fleabane is not an uncommon wildflower, but still pretty to see.
Floating bladderwort is a rare plant species found in freshwater ponds and bogs. It is named for its tiny bladders that create a thick net-like mat in the water. These bladders provide a microhabitat for very small fish and insects. They also capture and consume minute aquatic organisms, which give the plant its nutrition. This bladderwort has several floating leaf stalks, resembling the spokes of a rimless wheel. They support the yellow-flowered stem above the water. --National Park Service, NJ Division of Parks & Forestry
