About 10 plants with open flowers. Pollinia were seen on the labellums of two flowers on one plant. On the lower of these, the column can just be seen. Pollinia seem to have gone so they may have fallen onto the labellum rather than being left by a pollinator. In the second plant shown, pollinia were seen on the back of the dorsal sepal. This could be the work of an insect that missed its target. Sadly, both these flowers, and most of the others, had vanished by my next visit three days later. Their remnants are shown in the second pair of photos. Fresh roo poo in the middle of the colony suggested the culprit.
