Glyptostrobus europaeus (Brongn.) Heer in Arkansas

Glyptostrobus europaeus (Brongn.) Heer, a fossil gymnosperm is found at a few locations in central North America, in deposits of the Eocene. This work cites previously reported localities and reports a new site at Hooker, Arkansas. This deposit appears to be the most abundant for specimens of G. europaeus in the Eocene of North America. History of the Hooker site, characteristics of the living species G. pensilis (Abel) Koch and G. europaeus is presented. Worldwide distribution of both species through time, is discussed. Specimens of many parts of the life cycle of G. europaeus are recorded and illustrated
