Fagales (Oak)


The order Fagales is a well‐defined group of woody flowering plants with considerable economic and ecological importance. Common species include the alders, bayberries, beeches, beefwoods, chestnuts, hickories, oaks, walnuts and southern beeches.

Keywords: wind pollination; oaks; rosids; biogeography; angiosperms

Phylogeny of extant and fossil Juglandaceae. The fruits of extant taxa depicted across the top are, from left to right: Engelhardia, Oreomunnea, Alfaroa, Platycarya, Carya, Cyclocarya, Pterocarya and Juglans. Extinct juglandaceous fruits based on their appearance in the fossil record are, from left to right and bottom to top: Casholdia microptera, Palaeocarya puryearensis, Paleooreomunnea stoneana, Paraengelhardia eocenica (Engelhardioideae); Platycarya americana; Paleoplatycarya wingii; Hooleya lata; Hooleya hermis (Juglandoideae: Platycaryeae); Polyptera manningi, Cyclocarya brownii, Cruciptera simsonii and Pterocarya macginitii (Juglandoideae: Juglandeae: Juglandinae).
