catasetum susan fuchs 'yellow bird'

catasetum susan fuchs is a hybrid between orchidglade and expansum. the earlier is the primary hybrid between pileatum and expansum. there are many variety of susan fuchs, yellow bird being one of them. at a glance, it looks somehow like a pileatum but the presence of small calluses just beneath the depression at the labellum tells us it is not. the presence of the calluses are from the expansum influence.
i bought this seedlings about a year plus ago, though this spike has only two flowers but there are already three spikes emerging from this plant, so basically no complaints (shown in first pic)
