Looks like a cute plant! I just googled it. Here is what I found for ornithophora radicans (maybe someone has orchidwiz?):
Dwarf epiphyte for cool or intermediate house. Forms large colonies of small pseudobulbs with grass-like foliage. Flowers are delicate, pale and charming in mass. Fragrant.
Considering this was grouped with mounted plants, I'm thinking it likes good air movement and humidity. To me, it resembles my oncid twinkle, and this plant likes to be evenly moist and semi-shade. I do let it get drier in the winter, but during the growing season, I water 2x a week and mist daily while keeping the air moving well.
Hopefully others who know this plant more intimately will chime in good luck with it though, it is cute!
