In most Xeottiinae (figs. 174, 176) the filament is thin, but strong enough to hold the anther in its place after removal of the pollen. In other Orchids, on the contrary, the anther usually separates so easily from the thin filament that it almost always falls when the pollen is Fig. Please note that these images are extracted from scanned pa
