Macrophotograph of an inflorescence,or flowering shoot,of Cocksfoot grass Dactylis glomerata releasing its pollen in a breath of wind. The yellow dangly structures are the anthers,the pollen-producing bodies of the flower. The anthers are suspended on the ends of threadlike stamens,both structures together forming the male reproductive organ. There are many strains of this common roadside,meadow & wasteground grass. They flower from June to September,producing large quantities of pollen,which is dispersed by the wind. The pollen is responsible for the seasonal allergy known as hayfever | |
