The last part:
Thunia alba (and Ctsm)
Stanhopea lietzei
Phalaenopsis violacea alba (two pics)
"Interesting orchid" (I forgot to pic the name of this one, sorry; someone could help?)
NOID Bifrenaria, probably a natural hybrid or a new species (I want this one! I want this one!)
And the winner is...Cattleya harrisoniana (two pics) huge plant, wondelful flowers, but not my choice (I prefer L lobata 'Geni' for the Great Prize)
Last but not least, Bulbophyllum baliense (not much stinky
)
