FuglyDragon Posted July 28, 2010 Report Share Posted July 28, 2010 Anyone able to ID this plant ? I filmed it in a small tributary of the upper Rakaia River in North Canterbury, collected some and its growing well in my fish room, I just have no idea what it is, anyone care / able to enlighten me ?

Ira Posted July 28, 2010 Report Share Posted July 28, 2010 Looks like hygro polysperma. But that's not a native. How do you know it's a native if you can't identify it? Quote Link to comment Share on other sites More sharing options...
FuglyDragon Posted July 28, 2010 Author Report Share Posted July 28, 2010 Don't see how it could get into a small creek in the middle of nowhere if its not a native, have also seen it in the Irwell stream that flows into lake Ellesmere.

phoenix44 Posted July 28, 2010 Report Share Posted July 28, 2010 Leaves are too large to be polysperma. Wait for simon to see this. I suspect it will be a native aponogenton of some sort. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted July 28, 2010 Report Share Posted July 28, 2010 Simon will be your man--I think he has had an ID on that previosly. If I remember it was not a native or polysperma. Can't remember though. Quote Link to comment Share on other sites More sharing options...

supasi Posted July 29, 2010 Report Share Posted July 29, 2010 Cant tell from the video. You say you collected some. Are you able to take some pictures close up of the stem and leaf structure. I am interested to know what it is also. I am currently on the look out for new plants to be used in an aquarium. Quote Link to comment Share on other sites More sharing options...
Cricketman Posted July 29, 2010 Report Share Posted July 29, 2010 Gymnocoronis spilanthoides Unwanted organism.. EDIT: I Should say that this is my guess, and others may well prove me wrong. Quote Link to comment Share on other sites More sharing options...
livingart Posted July 29, 2010 Report Share Posted July 29, 2010 Gymnocoronis spilanthoides Unwanted organism.. but almost impossible to eradicate Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted July 29, 2010 Report Share Posted July 29, 2010 If that is the plant that used to be called Hygrophilla costata and was sold as a coldwater pond plant the leaves look far too large to be the same plant. Quote Link to comment Share on other sites More sharing options...
FuglyDragon Posted July 30, 2010 Author Report Share Posted July 30, 2010 Wonder how on earth it would get into a high altitude tiny spring creek in the wilderness miles from anywhere ? the creek in question was draining an area of swampy marshy ground and was at most 2 to 3 feet wide and maybe 18 inches to 2 feet deep. Ill get some close up photos of it this weekend and post them. Quote Link to comment Share on other sites More sharing options...
Deleatidium Posted July 30, 2010 Report Share Posted July 30, 2010 Aquatic introduced plants and animals can be found all over the place even in seemingly isolated locations. To ID it and any other aquatic macrophytes download the NIWA quickguides at: http://www.niwa.co.nz/our-science/aquat ... uickguides Quote Link to comment Share on other sites More sharing options...
