The results of ten years of continuous monitoring of airborne pollen concentrations with a volumetric pollen trap in Perugia, have revealed some likeness and differences, concerning the time, the quantity and the quality of the monitored pollen grains during the studied period. In the atmosphere of Perugia, Cupressaceae/Taxaceae, Fagaceae (Quercus), Poaceae, Oleaceae and Urticaceae are the main taxa; the first peak at the end of the winter, Fagaceae (Quercus), Poaceae and Oleaceae in May and June, while Urticaceae has a very long period of pollination with many peaks during the spring-summer period.

Hasta el momento, las comunidades de este orden eran conocidas de la cuenca mediterránea, aunque su expansión en California y Baja California ha sido tan extraordinaria que hoy constituyen la denominada por los ecólogos norteamericanos pradera californiana.; [EN] A phytosociological description of the new association Brassico tournefortii-Hordeetum leporini, belongs to the Brometalia rubenti-tectori order, is made. At present time, the Brometalia rubenti-tectori communities were only known from Mediterranean areas. However, they are extraordinarily spreaded in western North America, where have been labeled as "Californian prairie" or "valley grassland".
