They - this one and a couple of other laelia species - were called "the anomalous laelias" because they look different from the Brazilian etc ones, and are separated from them by a couple of thousand miles , with never a laelia in that distance. Maybe now that the Brazilian ones are all cattleyas, these are the only true laelias left -I haven't stopped to try and check up.
I saw this species growing at a roadside eating place on the pan-American highway in Costa Rica some years ago - several collected plants all in glorious flower - tied to a tree. My spanish is very poor, but much better than their English and all I could get from the bartender, before I was torn away to get on the bus again, was that they came from the forest "above" - i.e. up the mountain. I couldn't identify it - never thought of looking at laelias - the bulbs were "all wrong" for cattleya alliance - but someone at Kew identified the photographs when I got home.
I've had it on my wish list for the past 10 years, and only yesterday bought a single - probably very small - seedling at an auction site. Seeing your pic whets my appetite to see it again.
