Antwort auf: Re: C.debile - question! von Peter Corkhill am 13 April, 2001 um 20:30:51:
I am not sure whether our imagination of insects crawling over the staminode and falling into the lip of a lady's slipper is right in all cases. Werner Frosch once observed an insect flying with high speed against the staminode of C.calceolus. Through the impact the insect was thrown into the lip, quicker than Werner could look. Shortly afterwards it left the lip through the "back door", packed with pollen.
Perhaps C.debile has another, different way of catching the insects for pollination? It will always be hard to tell, as this moment can rarely be observed. However I will have a closer look on the flower and see whether I can find a hint in the construction of the lip and staminode.
