Dendrobium pierardii. This usuallyflowers in early spring after an enforced drought (I stop watering in October until all the leaves have fallen off and resume in March when the first buds have formed, yes you read that right).
Diocentrum (Doritis x Ascocentrum interspecific cross)
(Well is it or isn't it?)
Psychopsis papilio or the famous Butterfly orchid
Gone and sadly missed: Barkeria and Phaeus tankervilliae
