| | I think the variability of Phal pulcherrima is only a half truth.
Besides having 2 very similarly looking sister species in Phal buysonniana and Phal regneriana, many better strains of Phal pulcherrima in fact have Phal equestris as an ancestor a number of generations back. Then, some plants have also been chemically treated to increase their chromosome count (from 2N to 4N).
This situation mirrors that in Vanda (i.e. Euanthe) sanderiana whereby so many hybrids that have Vanda tricolor var suavis or Vanda coerulea as a remote ancestor are now virtually indistinguishable from the true species plants, except for their heightened colour, freer flowering habit and longer inflorescences and greater vegetative vigour.
