Well, after further careful perusal of the upper deck: Den. aggregatum or lindleyii has a spike ready to pop, and 3 more coming.
Looking at this cork raft with fresh eyes, it does appear that I have "Big and Little" on there, the regular aggregatum on the left end with bigger leaves, and the lindleyii on the right end, smaller leaves and blooming sooner, too! The big one is just starting to send out little spikes off several pseudobulbs. I'm happy to have a succession of bloom on this one, they're so gorgeous, but rather fleeting.
Also literally bumped into a nice spike on one of my NOID Cymbidiums. It was sticking out horizontally and I nearly broke it off, bumping into it with my leg as I walked by. Luckily no harm done and 10 nice buds on this one.
Tried a new strategy with all my Cyms this winter, parking them on the north side of the house where it is cold and shady for about 6 weeks, then easing them back out into the sunshine. The little extra chill seems to have worked at least on this one.
