This is because several plant families such as the Chenopodiaceae, Amaranthaceae, Graminae (Poaceae) and Compositae have wide-spread, abundant, anemophylous taxa which occur as major weeds of both agriculture and waste places. Several characteristics will be presented about the ability of these species to be successful in promoting allergies on a international basis. Interestingly, many of these plant species have been included on weed lists of countries whose geography, ecological amplitudes, climates, and agricultural practices are similar. The subsequent reproductive strategy for these species will be reviewed and biological traits discussed with reference to pollen grain production, and dispersal methods or importance as both weeds and hayfever plants.
