UV-induced fluorescence in the flowers of certain pygmy and tuberous Drosera and in the traps of Drosera barrettiorum
Abstract
Two phenomena connected to UV-induced visible autofluorescence in Drosera are reported here: 1) bright blue UV fluorescence of anthers of certain Australian pygmy and tuberous Drosera (D. sections Bryastrum and Ergaleium), likely connected to the attraction of crepuscular pollinators; 2) bright blue UV fluorescence of the yellow, potato crisp-like modified tentacles of D. barrettiorum (D. section Arachnopus), likely connected to prey attraction and probably serving as anther/pollen mimicry to attract (crepuscular or nocturnal) pollen-feeding insects.
