Nice dendrobe, Maura. Can't help with the ID as there are lots of similar looking phal-type denrobes around. I'm afraid you've cut back the cane instead of just the spike. I'm posting pictures of how to cut back the spike, leaving about 1/2 inch to 1 inch of the spike. As you can see from my pix the old cane is capable of producing new spikes in sequence or multiple spikes all at once or in sequence. The same canes can also produce keikis at the top as well as at the base. I've had keikis growing out from the green stump of the cut spike. You have done the right thing by applying cinnamon to the cuts.
