Taxonomic remark From Philippe & Bamford, 2008: The lectotype chosen by Andrews (1955) for this generic name is based on a specimen whose transversal walls of ray cells are “not well enough preserved to show in radial section” (Stopes, 1915: 149). The other syntype has rays with Abietineentüpfelung and no ray-tracheids (Seward, 1919: Fig. 724 F), features that make the genus a taxonomic synonym of Protopiceoxylon Gothan. To be “saved”, i.e. used for woods with an anatomy fitting the original diagnosis, this genus has to be neotypified. The two syntypes aside, only one species was assigned to this genus, P. arcticum Selling, later recognized as the wood of a Cycadeoidea root (Selling, 1951). [details]
