ID for orchid that blooms only once in 10 yrs

[MESFLR]

This my first post and it may sound strange. I was given and orchid and told that it bloom one in 10-15 years. The tag is hard to read but here goes:
not(st)childiam - (B(r)noo x Charles E)
The letters in parenthesis are questionable.

My hope is that someone may be able to ID this Orchid.
It was doing fine now one of the leaves just limped down.

Thank you so much,
