I'm sure I've posted this in the past couple of years. It flowers randomly through the year for me. It does have an unpleasant scent, if you stick your nose right into the flower. Otherwise, you really don't notice any odor. The umbel is rather large which is nice for a Bulbophyllum, but doesn't last more than 4 to 5 days.
wow...your annandalei is really nice, the spots are so prominent and not to mention the strong yellow background of the flower. mine comes in a very light yellow tone and the markings are not as prominent, very nice specimen you got there. thanks for sharing
