Andy has one Notylia species (trisepala), and about 10 Oberonia. Ask Katrin to get you the correct Oberonia species names, which I sent her a after the Southland Orchid Show.
Notylia is particularly tricky to get. Santa Barbara Orchid Estate has one more, and I pre-ordered some from Peruflora. I think so far I managed to get four or five species of Notylia, about 30 of Oberonia. There are about 60-70 Notylia species and about 150-300 Oberonia.
