Vegetation and proportions make me think aphyllum more than any other species, but as others have said reliable ID might never be possible even with blooms. I've bloomed an aphyllum smaller than your plant though not a couple others of similar age and greater size, but assuming that's the right ID yours certainly has the potential for flowers in the spring. If you like this kind of Dendrobium, anosmum and loddigesii are also pretty great and shouldn't be hard to grow and bloom in your climate.
Not a good idea to repost someone else's photos without explicit permission, BTW, as technically it's a violation of the owner's copyright. Better to just link directly to it, about which Orchidboard is thankfully very relaxed.
