"... collected ... from many locations [TAS, NSW]. Genetic match to the new U. clathratioides L.G. Kraft, Kraft & R.F.Waller in Kraft et al. (2012). If our identification is correct, the "new endemic" would have to be subsumed into the global (introduced to Australia?) U. torta." (Kirkendale et al. 2013). - (15 May 2013) - Wendy Guiry
