Thanks for the help so far. 46er, that's a great resource, thank you for sharing. According to the article posted and other resources, there are between 12 and 15 bladderwort species in NJ. I'm going to list the ones that I can confirm from Boyd's book "The Ecological Pine Barrens of New Jersey" as well as several other sources, however I can only come up with 10. I'd like to try to get a complete list and then take it from there. Can anyone help by confirming, refuting, or adding to this list?
Horned bladderwort (Utricularia cornuta)
Humped bladderwort (U. gibba)
Swollen bladderwort (U. inflata)
Flat-leaved bladderwort (U. intermedia)
Southern bladderwort (U. juncea)
White-flowered bladderwort (U. olivacea)
Purple bladderwort (U. purpurea)
Reclined bladderwort (U. resupinata)
Zigzag bladderwort (U. subulata)
Striped bladderwort (U. striata aka fibrosa)
I'm also interested in finding out if U. foliosa, U. macrorhiza, and U. radiata are native to here, I couldn't find anything confirming it.
