Hey everybody I'm one of those guys into planted aquaria.
Anyway a guy on our forums collected this the other day and had no idea what it was.
I said it was a utric but wasn't sure what type. My guess is U. uliginosa. It was reportedly collected in less than 5 cm of water. Collection was in This dam in SE Queensland, Australia.
Sorry, no pictures of the flowers as yet.
Thanks in advance.
