I acquired on of these when I first began keeping orchids, back about Y2k.
It didn't do very well for me when trying to grow it in my Alaskan living room.
It bloomed once, then refused to do so a second time.
Finally, it wasted away after 3 years or so of disappointment with it.
When I got it, it was named Den. porpax.
Then, I saw this one in a local grower's setup over a year ago.
It was in bloom , somewhat, and was named Epi. porpax.
I immediately recognized the flower and was intrigued.
So, I snagged a copy of it.
I placed it under the eaves on the West side of the house.
It began wasting away like the 1st one.
So, I moved it along with a few others to a more shaded area on the branches of the Geometry Tree.
It likes it there!
It is not the prettiest orchid, but it took me over 15 years to figure out how to grow it.
That counts for something.
