I have one that was purchased as a a purple-lipped Philippine species and suspect it is smithandii. It has the same lobii like flowers but much smaller than lobii Mine is currently in bud as well. The vendor swears that this plant is not smithandii but comparing my pics with yours they look fairly identical.
Jean would you be able to take measurements of the flowers, leaves and p-bulbs for me please?
Ron, your flower looks definitely just as mine with identical coloring of the lip (that is swinging as the lobbii lip does).
some measures (examples): leaf length 13cm, width 5cm, pseudobulb length 2,5cm
when compared to my lobbii, for the smithi the leaves are shorter (lobbii 22cm), but larger (lobbii 4cm), the bulbs are smaller (lobbii 3,5 cm)
