¹A fascinating exception is the Madagascan orchid (Cynorkis uniflora) (Nilsson et al., 1992). Attachment of pollinia, which have extraordinarily long (16 mm) rigid caudicles, to the eyes of visiting hawkmoths is very chancy, but the pollinia that do attach bring about numerous pollinations. Often more flowers are pollinated than pollinia removed, especially at high flowering densities.
