The plant definitely is U. uniflora. The lower corolla lobes of this form bend backwards to create a thinner looking flower than what is normal. It originates from Triffid Park a few years back (they no longer have it- they managed to kill it off) and was collected by Colin Clayton during one of his trips along the east coast. Not one of my favourite forms TBH, I prefer the more open flowers- those that Matti refers to from the Royal N.P.
