Looking at the following pics (1st link below) would anyone care to identify the plant in pictures 51&53 on page 3? I certainly think this is N.macrophylla, but looking at the slightly irregular protrusions on the peristome (spiking) it reminded me of the debate regarding this characteristic seen on one of Wistubas macrophylla clones (2nd link below). On Wistubas clone the protrusions are more exaggerated and it is regarded by some as being atypical ie. a hybrid (N.trusmadiensis). My N.x trusmadiensis or for that matter any other trusmadiensis I have seen look nothing like this plant or Wistubas clone which display none of the lowii characteristics typically seen on the underside of the lid. Perhaps these photos show that N.macrophylla can have an irregular peristome. Any thoughts?
