It would be so nice to start a new political party. Maybe name it, The Tea Party II for Americans, not racist anti-American douches that hate their neighbors? We need to reform our politics, not make them more partisan and dumber.
Taylor (page 131) writes: "Utricularia arnhemica shares with U. humboldtii the distinction of bearing the largest traps known in the genus, but the very large ones (up to 1.2 cm long) are only produced when the plant is growing under the most favourable conditions."
Bob, I know this sentence by Taylor just too well since I have this plant, this line really haunted me - as I want to come as close to the ideal conditions for my plants as possible, and so the trap size in my arnhemica became a kind of indicator for my conditions. Well - I am very satisfied
My conditions are: high water level (up to the soil level), high temperatures (around 35°C /day, above 20°C /night), and a very high light level (1000 Watt/sqm fluorescents in 25cm distance, what yields in a light level close to 100.000 lux). I use a sand/peat mix with a high amount of sand (around 2/3).
I also had a double-take when I saw the first picture. I thought they were small Darlingtonia.
Martin, have you teased the "appendages" to see if the bladder trap responds? Could the traps catch prey without being submerged? These traps are large enough that one might watch a capture without a microscope.
though I haven't tried so far, I expect that the traps have to be submerged to work.
I was on a trip for a month, in this time I had sealed the tank and provided a high water level, so the friend who did the vacation care had only to fill up the water weekly. I think the plant was submerged most of the time, and that this is one of the necessarities for the plant to build up those big traps. As said before, I think these traps are built for catching bigger prey of the open water. I will soon try out to trigger the traps and let you know then.
