| Usually with keikies you see a root tip or two. But are they swollen a little from side to side at the tip. If they are, that is the buds inside. I know that it is past their primary flowering season but as one great orchid lecturer often told me, "who said that orchids can read?" They bloom when conditions are right.

Are you really sure these are buds?   |

| From that angle that you have presented, no, they look like new vegetative growths. Rodney Wilcox Jones, my idol! Businessman, Orchid grower, hybridizer, lived to 107! |

| Im curious about these"vegetative growths","keiki" and pseudobulb things, As im told, this plant should let out new stems from the ground itself, emerging from some kind of underground structure called a pseudobulb.... Now, keiki, should spawn the upper bits of the stem... whats the difference? |

| Keikies actually form from vegetative eyes. Under some conditions some become buds, under different conditions they become plantlets. One school of thought is that nighttime temperatures that are too warm produce vegetative keikies. The underground structure is NOT a pseudobulb, it is a rhizome. The upright canes on your plant that carry the flowers and leaves are the pseudobulbs. The connective tissue between adjacent pseudobulbs is called a rhizome. Nobile Dendrobiums do not produce extensive rhizomes. Rodney Wilcox Jones, my idol! Businessman, Orchid grower, hybridizer, lived to 107! |

| Similar. They run along the surface of the media but do not produce roots ever as far as I can recall. Then the new growth, the new pseudobulbs, arise from the rhizome and the roots arise from the base of the pseudobulb. Rodney Wilcox Jones, my idol!

BigBill said:Similar. So.. ground sprawling keiki stems/ offshoot that emerge from the lower bits of the older stem and root immediately.... Good to know. Love learning new things about biology... |
