Ok, now for the convoluted, sometimes boring stuff. Gilded tower consists of four species in equal parts:
Oncidium wentworthianum, Rhynchostele (formerly Odontoglossum) bictoniense, Brassia (formerly Ada) keiliana, and Brassia arcuigera (formerly longissima, for those of you old enough to remember), so the current genus is Brascidostele. (For one brief moment in time it was Anikaara). So now you have two surprises.
