Thanks everyone!
There are some labels, just pushed into the pots, or hidden behind in the case of most of the orchids. The nepenthes are all quite easy to remember, each is quite distinct from the next.
About 100 cuttings are brand new from another grower who got them from another grower, and I guess his plants are old enough to have inner bred together. So those are going to be interesting to try and figure out.
Tillandsias are a little harder, I've got detailed photos of each one since I purchased it, and a database, but a few still look very similar.
