My little brother found a population of what I would call U.Aurea (as they are common here) in a temporary swamp near dads, I think that they originated from a mountain swamp (as these are more permanant) and was washed down with the recent floods.
The swamp is just overflow from a cane paddock and has previously had nothing in it (not even water lillies) as it gets alot of fertaliser and posion run off, it is a sandy clay soil and 10-100cm deep by 15m long and 3-4m deep, it dries up for 2-3months of the year and also has a cattle paddock further up from the small temporary stream that flows to it (the stream has a permanant mountain swamp at the top that occasionally gets Aurea outbreaks then they die off to a few plants for some reason.
The plants averaged at 1-1.6M long, a 4-5cm diamter and had the typical aurea flowers and 2mm traps, the odd part was that some (a few meters from the rest in the flowing creek) where red for the first 10-20cm of new growth then a dark green for the rest, as the paddock they are near is getting posioned (cane paddock) in a few weeks I grabbed a few and threw them into a pond I have established gibba in (man made pond).
The red utrics where also attached to the bottom at a depth of 50-60cm, but a few weeks ago this would have been 80-90cm deep, they also do not come within 10cm of the surface as the flow of the creek prevents this, the water is very clean (as most of the cow crap is filtered through nardoo and grass incursions intot the water, the PH is 6 in the shallows where the green plants are and 7 in the creek.
The green plants are all in flower but the red had none.
The question is are the red a variety, sick from a posioning or a different plant.
On a side note what are the distinguishing features of Aurea and Australis as both species are recorded near here but I have only ever seen what I would call aurea strains.
I grabbed a few pics but am going back to dads in a couple weeks to get more (and see the colony a couple days before its posioned.
I am in North QLD between Cairns and Townsville (if this helps).
