In a number of windpollinated groups among Fagales the flowers, especially the male flowers, are densely arranged in catkins and fill the (monosymmetric or even asymmetric) space created by neighboring bracts (e.
2003), but their sister taxa in the 'higher' Hamamelididae (= Fagales sensu APG III, 2009) such as the Betulaceae and Juglandaceae are regarded as predominantly Laurasian whereas the Myricaceae are widespread, but absent from Australasia (Manos & Steele, 1997).
Elsewhere in the Fagales, similar but reduced wings may occur on the trigonal nuts of some Fagus species and biwinged fruits occur in Alnus and Betula.
