Laelia tenebrosa alba. I advised a friend to get this and split it with me (she called for advice and info from a show) a couple years ago; a small weak bb div, we have babied it since. It's been growing in her greenhouse until we could get it to bloom and now is big enough for me to bring home my own piece. It has been a touch-and-go plant (she waters these too much), but I am girl that despite some worries it has bloomed out true to its label. Now I just need to try to get better pics of this rarity.
