I bought this a few years ago as Laelia lobata; however, I don't think it's probably that species (besides the atypical shape of the lip, the plant doesn't bloom at the correct time of year as Laelia lobata). Whatever it is, it's easy to grow and the blooms smell pretty nice. The only negative about the plant is that it has a rambling growth habit, with pseudobulbs spread far apart on a creeping rhizome that likes to climb out of the pot.
