Thanks so much for the welcome and the tips! I did post pictures, and I've been told that I'm the proud caretaker of a Miltassia.
I love plants (large south facing windows were paramount when I was apartment-hunting!) but I've never before had an orchid-- usually I stuck to spider plants, pathos and herbs! Hopefully, I'll be able to keep the Miltassia happy-- it's so beautiful! And I'm sure that I'll want more once the shock of oh-my-god-its-an-orchid has worn off.
