About P.parnatanum I have not many infos so I cannot be really shure about the origin...but I have seen many plants flowering that are selfing and are all really same so....
About P.sugiyamanum I have seen the plants in the wild on Mt.kinabalu area...so....Also there are 2 different colonies.One bigger and one smaller...little different but + or - same...I'm 100% shure is a species also because we sibbed it,produced in malaysia and flowered seedlings...all same...so genuine specie.
About P. intanniae...all plants around in the last years were evidently wild collected plants.I've seen personally some plants in flower in Indonesia and were really wild things...big multigrowth plants(so veery old ) in flower but terrible conditions...shurly dead after few months...I'va also seen flasks from taiwan and the plant is really easy to identifie if you have seen once an adult one...the leaves are different from all other species...also that one I am 100% shure is a valid one.Also looking at the flower there are no characteristics of other Paphs inside(no dianthum,no philippinense...is probably more near to supardii and gigantifolium).
