Tough call. But mine would have to be:
1) Den. Burana stripe (this was my very first plant, and it has never disappointed me).
2) Vanda Bronze Butterfly (A surprisingly tough, hardy little plant)
3) V. (Mimi Palmer "Teo Boon Hian" x coerulea)(Gorgeous, forgiving, and free-flowering. Need I say more?)
4) V. (Mimi Palmer "Teo Boon Hian" x Fuchs Delight)(See #3. Best impulse purchase I've ever made).
5) Bollea violacea (I love this plant)
6) Bollea lawrenceana (Survived a terrible fungal infection and sunburn, and
still has the will to live. Anything this tenacious is a keeper in my book)
7) NoID Cattleya (Neat plant)
8) Pescatorea cerina (One of the most forgiving pesc's ever)
9) Pescatorea dayana (See #8)
10) Zygo. (Blue Blazes x Blue Blazes)(AKA Colonel Mustard)
11) Zns. Cynosure "Blue Bird" (My collection would be incomplete without it)
12) Propetalum (Z. Artur elle x Promenaea xanthina) (very vigorous)
13) Galeopetalum Giant "Rhein Moonlight"
(I'd go for a Baker's Dozen LOL)
And of course, my paphs. But they're small, so they'd come anyway.
Still, I'd hate to leave behind any plants. All of my plants, even the problem ones, are special to me.
