I've got the same question as Henke had about Coel. cristata... is this a spike or a new bulb?

Hi Shakkai and Kalvin,
I am not an expert but here are some observations that I have made from my plants.
You can recognise these features in Coelogynes.
First has the spike got tightly overlapping bracts both below the first flower and above the last flower such as you see in Coelogyne prolifera.
Second has the spike got tightly overlapping bracts below the first flower as in Coelogyne barbata
Third does the flower spike arise from a "bud" at the base of the pseudobulb and then hang down i.e. perdulous as in Coelogyne tomentosa (syn Coelogyne massangeana)
Fourth does the flower spike arise from a bud at the base of the pseudobulb and then hang down and does the bud go on to form a new growth after flower as in Coelogyne dayana and rochusseni
Fifth does the erect spike arise from the centre of the developing pseudobulb/leaf and does the spike have more than one flower open at a time as in Coelogyne mooreana and Coelogyne trinervis
Sixth does the erect spike arise from the centre of the developing pseudobulb/leaf and have flowers that open in succession as in Coelogyne baccarii
Seven does the arching flower spike arise from the centre of the developing pseudobulb/leaves and have flowers that open in succession as in Coelogyne speciosa.
Eight does the arching flower spike arise from the centre of a developing pseudobulb/leaves and have flowers all open at once such as in Coelogyne cristata and Coelogyne flaccida.
Incidentally I have had difficulty successfuly growing Coelogyne nitida but the other mentioned above seem to flower and grrow without difficulty. Whatever enjoy them, they are a genus that needs to be grown more
