Really top list? hhhmmm... my list is more wide than long, which means most of the plants are on top
but, ok, I will post just 5 of them... no priority order...
1 - Sedirea japonica (red variety - see picture attached

I received this picture via e-mail form a vendor aus taiwan who was bringing them to the show in Locarno. Unfortunatelly, when I arrived he had sold the only one he had brought.. so, maybe next time

) <-- I hope I do not break any rules by posting this picture

To teh moderator: please feel free to delete it if you consider it non compliant with the OB Rules...
2 - Fredclarkeara After Dark (one day...

)
3 - Lepanthes telipogoniflora
4 - Paphiopedilum helenae (I am in love with this species... unfortunatelly, seems almost impossible to get one, as illegal in most countries, and the few vendors which are legal owners in Switzerland, just don't want to sell it

)
5 - Cattleya violacea in all forms... unfortunatelly, I have neither the place for them nor the right conditions to succeed with their culture...
