I found it!!!
I remember reading years ago a list of Cymbidium species listed by heat tolerance!
This is a copy from a post at the Orchidboard:
Species
Heat Factor
1Cym ensifolium subsp haematodes 10.0
2 Cym canalicaulatum 10.0
3 Cym aloifolium 10.0
4 Cym finlaysonianum 9.5
5 Cym ensifolium subsp ensifolium 8.5
6 Cym munronianum 8.0
7 Cym dayanum 8.5
8 Cym madidum 8.0
9 Cym bicolor 8.5
10 Cym atropurpureum 8.5
11 Cym chloranthum 7.0
12 Cym sinense 5.5
In other words the species ensifolium or a hybrid with ensifolium might have a good chance of doing well in a warmer climate. And so on......
