I lost this bud on Bulbophyllum claptonense that I posted above. I am disappointed. I can not say with certainty what happened.
It did elongate to more then twice the length of what you can see above. It suddenly color a good deal of yellow in the bud and dropped the next day. Try, try again.
I have more Bulbophyllum news. I did manage to get ahold of my third clone of Bulbophyllum Manchind. This is Bulbophyllum echinolabium x Bulbophyllum mandibulare. It reminds me of a compact version of Bulbophyllum Lindsey Paris. It is a sequential bloomer on shorter inflorescences. The first two clones are the burgundy variety. This new one is kind of an old gold color with burgundy or red burgundy veins. Lip is solid burgundy.
This is a good sized plant in a 6" pot. I am hopeful of future divisions. The other 2 are producing very large new growths in 3 1/2" pots. I am excited about that!
