Aug. 29th 1863.

Acropera luteola

Labellum, sides lobes turned over & united like [slipper] of Cypripedium, making labellum tubular: End of Lab. turned over & making a little closed cavity above with thick sides.

[insertion:] for growing

In lower tube fluid secreted from surface. lower surface [illeg] with secreted fluid.

I do not doubt that Probably insect crawls in depressing labellum by it hinge & touches rostellum by its tail (mem. Musk orchid) Same difficulty of forcing in pollen-masses as before.

I fertilised 2 flowers.
