I bought this as "Potinara Marie Sweet Orange" from my favorite orchid nursery here in Brazil, and they were kind enough to send me a second one for free!
I found it on register as
Rhyncattleanthe Marie Sweet Orange, a cross between Rlc. Sweet Amy and Ctt. Trick or Treat.
The plant is unifoliate, very compact with small bulbs and short leaves. Apparently it is very floriferous as well, since each orchid has 4 spikes. It was listed as fragrant, but so far I couldn't detect anything.. maybe in a few days. Colors are amazing on both of them and are the kind cameras have a hard time capturing.
This clone is called "Aquila"
And this one is called "Toranja". The name couldn't be more fitting - toranja means grapefruit in portuguese, and this is the exact same color as the inside of a grapefruit.
Now I'll have to make room for an unexpected orchid!
