Abstract
Fossil wood representing the tribe Engelhardieae of the Juglandaceae is reported for the 1st time. The genus ENGLEHARDIOXYLON is created to accommodate fossil woods and anatomy like that of modern genera in the Englehardieae. Two middle Eocene species of Engelhardioxylon are described, one from eastern Oregon [USA] (E. nutbedensis sp. nov.) and one from southeastern Texas [USA] (E. texana sp. nov.). The anatomy of these fossils is indistinguishable from that of the modern genera of the Engelhardieae, i.e., Englehardia, Oreomunnea and Alfaroa. The uniformity in wood anatomy between these fossils and the extant genera of the Engelhardieae suggests that a common pattern of anatomy, established during or prior to the Eocene, has been retained despite the morphological differentiation of fruits and foliage.This publication has 7 references indexed in Scilit:
