These are terrestrial plants from Africa and several come from Madagascar.
I would suggest googling the genus and a few vendors will pop up!
Not to be too snooty, but not many people carry Oeceoclades.
They are not native
They come from bulbs
Are not very desirable or showy.
If very few people want to purchase them, who will bother stocking them?
My suggestion is to buy whatever you can find.
