Fritillary Stock Video Footage


Fritillaria is a genus of herbaceous bulbous perennials. It is characterised by nodding (pendant) flowers, perianths campanulate (bell- or cup-shaped) with erect segments in upper part, a nectarial pit, groove or pouch at the base of the tepal, anthers usually pseudobasifixed, rarely versatile, fruit sometimes winged, embryo minute. Flowers often solitary and nodding, but some form umbels or have racemes with many flowers. Perianth campanulate (bell- or cup-shaped) and its segments usually tesselated with squares of alternating light and dark colours. Nectaries are large and well developed, and in most species (with the exception of Rhinopetalum), are linear to lanceolate or ovate and weakly impressed upon the tepals. The bulbs typically consist of a few tightly packed fleshy scales with a translucent tunic that disappears with further growth of the bulb. However, some species have naked bulbs with many scales and loosely attached bulbils, resembling those of the closely related Lilium. Certain species have flowers that emit disagreeable odors. The scent of Fritillaria imperialis has been called "rather nasty", while that of F. agrestis, known commonly as stink bells, is reminiscent of canine feces. On the other hand, F. striata has a sweet fragrance. Fritillaria represents the most extreme case of genome size expansion in angiosperms. Polyploidy is rare, with nearly all species being diploid and only occasional reports of triploidy. Reported genome size in Frit...
