Unknown orchid

[Marinarawr]

Hello! I'm new to the forums and I also have an orchid that needs identification. I've had it for a few years now (3-4) and I'm assuming that it won't be growing any more than it has already. There were originally two (same type) but one lives with my mother and unfortunately she got the one that blooms regularly. The flowers are very tiny, light purple, and grow on sort of a zig-zagging stem. I've tried in vain to find a photo of any flower that's similar to the one this one produces but I was wrong in assuming that there weren't many types of orchids . Anyway... enough of my jabbering.

Pot is ~6.5" across the top


Thanks in advance for the help
