Wilsonara growth habit

[dbarron]

Well, I got this/these from Olympic Orchids, as mericlones. Actually the order was incorrect (I had ordered two different Wilsonaras, but the picker gave me two Tan Treasures instead). Anyway, this is the first time for me to get one of this group (yes, I know it's a tri-genus cross), and I assume habit resembles Miltonia, or does it?
I was surprised that they have basically doubled in height since early October (I keep saying that..but it did surprise me). And my expectation is/was that they would reach blooming size on a future (probably like third) pseudobulb. However, this single growth is now approaching the size of a mature miltonia (not quite..but getting there). Help me align my expectations, then if something happens earlier, I'll be surprised
