The bottom few nodes are swelled up and I'm hoping that it may form keikis. The psuedobulbs are pretty shriveled up and now it's trying to bloom so... maybe it's using up its remaining reserves and wither after this.
yikes! are you planning on letting it bloom or cut the spike to let it conserve some energy to produce keikis? you still have the mother plant, I guess, and it's not like there's no hope for keikis if you let it flower...
