I wonder, what an 'unreal' gratrixianum would look like?That is the real gratrixianum from Laos. Note the very broad leaves. Dodidoki I think your plant is christensonianum!
I actually agree. Looks like my daoense.I wonder, what an 'unreal' gratrixianum would look like?
If we follow the overview of the P. gratrixianum complex by Averayanov, Gruß et al. in Die Orchidee (attached - in German, I know, but very profusely illustrated), I would be more tempted to identify Istvan's beautiful flower as P. gratrixianum var. daoense.
No, according to the overview article, I attached, yours look more like var. christensonianum (even if you don't read German, the photos still say a lot!)So this one must be daoense then? It's a seedling with select parents from Ching Hua, second time blooming.
