Very nice colour, and it Looks as if the plant is compact. Good buy!
I needed to look up the name since Oncostele doesen't explain the Miltonia spectabilis var. moreliana which is so obvious in the flower.
SBOE gives the genus name as Odontonia (not Odontioda!), which is Odontoglossum x Miltonia. The cross is Oncostele Sheraton x Miltonia spectabilis var. moreliana, with Oncostele Sheraton being Rhynchostele bictoniense x Oncidium harryanum.
I couldn't find a name for the hybrid genus Rhynchostele x Oncidium x Miltonia. In fact, I couldn't find this cross in the RHS data base (which doesn't mean much).
Since Odontoglossum has been declared part of Oncidium, the name Odontonia is not current anymore. Otherwise, you could well use Odontonia, or if you accept Rhynchostele, Rhyntonossum as a name for this combination.
This is crazy.
