A close inspection of one of my L. bicolors turned up what I believe is a keiki forming on a spike. It's too small and my phone cam too crappy to get a clear pic. Do they grow in this manner?
Cattleya Alliance plants, other then reed stem Epidendrums and a few oddballs, rarely get keikis. When they do it is usually at/near the top of the pseudobulb rather than on a spike. But if you're getting leafy growth, watch for roots. You never know.
