Epicyclia. Mabel Kanda 'Miyao' (Enc cordigerum x Epi floribundum) is a spring bloomer and I don't have Encyclia randianum in my collection. (It used to be called Enc randii) So your plant has Encyclia and Epidendrum in it.
I would expect upright growths but I suspect yours looked like it does from the way it was grown prior to you getting it. Your culture research is correct. I keep my high in the greenhouse hanging from a pipe, in a wood basket.Good humidity and watered 1X per week at this time of the year. 2X per week in the heat of summer.
The color is from randianum which has a purplish flush to it's leaves.
Here is a thread with some info
