My pick:
Amesiella Monticola
Angreacum Didieri
Sophronitis Cernua
Dinema Polybulb
on
Dendrobium Kingianum
Dendrobium Laevifolium
Gastrochilus Japonicus
Maxillaria Tenuifolia
Mediocalcar Decoratum
Rhyncholaelia Glauca
Underlined some spelling mistakes, makes it easier to find them on IOSPE
Every single one of them is quite uncommon and great flower and foliage.
For me the top would be Sophronitis Cernua, Rhyncholaelia Glauca (Rhyncholaelia have very amazing flowers) and Dinema Polybulbon.
Nice suggestions for plants i must say good work to all
Edit: If your having trouble picking 10, what i did was open all of them on IOSPE and narrowed them down by removing the ones i couldnt grow culture wise, then removed the ones i disliked most and had 10 left.
