Id and Culture Info Needed on "Leafless" Orchid

[D&S Mabel]

Hello Again:

Its a rainy day here in Central Florida and I was spending time looking through the forums.

I hope Susanne B (cb977) won't be too upset with me but I stole one of her photos as it helps with the questions I am about to ask!

What orchid is this in Susanne's photo?


I have the same orchid, I think:


I have mounted it on this fir bark stick where it is in direct sun for 5-6 hours per day and gets water twice a week (or whenever it rains) and fertilizered weakly weekly:


It has bloom once, the first year I had it and has not again over the last 3 years.

There a better way to handle its culture needs?

Any info and advice is appreciated!

Susanne B (cb977) - thanks for the "lend"!
