AB  - Fritillaria is a genus consisting of 130 to 140 species of bulbous plants, native 
      to temperate regions of the northern hemisphere. Generally viewed as an insect 
      pollinated genus with the exception of two North American species, Fritillaria 
      gentneri and F. recurva, which are described as hummingbird-pollinated and the 
      Asian species, F. imperialis, described as passerine-pollinated. These pollinator 
      shifts are possibly the result of adaptive changes to the structure and 
      morphology of the nectary, as well as a change in the nectar concentration and 
      composition. A study was conducted in a target group of 56 Fritillaria species, 
      based on the morphology of their nectaries and nectar composition to assess the 
      significance of pollination mode as well as its predisposition for the evolution 
      of bird pollination. All species studied had nectaries located at their tepal 
      base and produced nectar, but their size, shape, color, and composition all 
      varied. Most fritillaries had hexose-rich nectar, in easily accessible and 
      unprotected nectaries. Scanning electron microscope (SEM) analysis revealed that 
      the surface of the nectaries of most Fritillaria species was flat and clearly 
      distinct from that of the surrounding tissues, which might be regarded as an 
      adaptation for insect-pollination. Nectaries of F. imperialis were considerably 
      larger and had dilute nectar without sucrose, which was produced profusely, 
      thereby fulfilling the criteria characteristic of ornithophilous flowers. The 
      copious nectar of presumed hummingbird-pollinated species was rather balanced and 
      of medium sugar concentration. Their large lanceolate nectaries contrasted 
      sharply with the tessellated background of their tepals. These characters might 
      indicate a mixed pollination system that engages both birds and insects. Floral 
      anatomy and microstructure and nectar composition for Fritillaria species in 
      subgenera Korolkowia and Liliorhiza are studied for the first time.
