Abstract

German
Rundblättrige Glockenblume; Honigbiene. Die melittophilen (bienenblütigen) Pflanzen werden von hummel- bis kleinbienengroßen Hymenopteren bestäubt. Honigbienen saugen Nektar aus der Saftkammer der Glockenblumen. Dabei berühren sie ventral den zunächst als Pollenträger, im späteren Stadium als Empfängnisorgan dienenden Endabschnitt des Griffels.

Structure and pollination of a bell-shaped bee-flower are shown by the example of the Harebell, Campanula rotundifolia. The visitors - honey-bees - suck nectar from the protected epigynous chamber on the flower bottom. Hereby they touch ventrally the style which is immature at the first stage of the protandrous flower, serving as a pollen discharger; during the female stage the stigma is exposed in the same position. The process of development of both phases is presented by quick-motion pictures.
