	Betulaceae in Flora of North America @ efloras.org
		Betulaceae belong to an ancient lineage, traceable in the fossil record to the upper Cretaceous.
		The pollen of modern Betulaceae is much more specialized than that of modern Hamamelidales, however, and the relationships of the Normapolles complex to Juglandaceae, Fagaceae, and other amentiferous groups, as well as to Betulaceae, are not certain.
		Members of Betulaceae are economically important as timber trees, as the source of hazelnuts and filberts (Corylus), as ornamental trees and shrubs, and as aids in soil nitrification and stabilization (Alnus).

		That, although the floral anatomy of the Betulaceae may give indications of a reduction instead of primitiveness, yet there are other facts which must be taken into consideration.
		That the Betulaceae in general show clear evidence of a primitive aggregation of specialized rays in relation to the appendages, and that these rays become subsequently diffused throughout the structure of the wood.
		That the general internal anatomy of the Betulaceae and especially the ray structures supply no proof for and much against their being placed anywhere but near the base of the Dicotyledons.

		Alla famiglia delle Betulaceae appartengono piante legnose, distribuite prevalentemente nelle regioni temperate e fredde.
		La famiglia è suddivisa in 2 sezioni: le Betuleae (Betula, Alnus), caratterizzate dal possedere fiori femminili nudi e fiori maschili perianziati, nonché da frutti separati dalle brattee e dalle bratteole e le Coryleae (Corylus, Carpinus, Ostrya), con fiori femminili perianziati e maschili nudi e frutti involucrati.
		Alcuni botanici separano le Coryleae dalle Betulaceae e le elevano al rango di famiglia, con il nome di Corylaceae.
