Some confusion on my part with Aerides quinquevulnera var purpurata. Jim Cootes came to the rescue. Was actually bought as Aerides odorata var. calayana. Was acquired as Paphiopedilum fowliei, but Jim Cootes identified it correctly. I think this is the more classic form. Jim Cootes suggests that this may be a from a locality other than the previous P. lueddemannianas posted, as the colour form is a bit different.
