This was supposed to be a separate post but I accidentally included it as a reply to my Stanhopea post. Anyway, reliable bloomer and does well in my windowsill and outside in summer.
It has 13 flowers and checking my records it has bloomed with between 10-13 flowers per spike in the past. My best was two spikes with 21 flowers total. I believe it could bloom more than once a year under the right conditions but has not ever done so for me.
