Update on Walkeriana
There is always more to learn about orchids. C. walkeriana is one of only two species of Cattleya that grows it's flower spikes from an independent growth coming from the base of a mature rhizome, not from the top of the pseudobulb. A new pseudobulb or a flower spike will start off looking exactly the same. Until either a leaf or buds grows out the top it's hard to tell which one it's going to be.
