Taxonomic remark Substitute name for Spiroxylon J. Walton 1925, non T. Hartig 1848. (Index Nominum Genericorum). Currently used as accepted name; Philippe & Bamford, 2008 state: This generic name rests on a type species, P. africanum, with Spiroxylon africanum Walton as a basionym, the age of which is unknown (Walton, 1925: 22). The genus original diagnosis clearly states that radial pits cannot be rounded and isolated. Thus only wood with strictly araucarian radial pitting should be assigned there. Prototaxoxylon Kräusel et Dolianiti is a junior nomenclatural synonym of Spiroxylon Walton non Hartig, as Walton clearly described Spiroxylon as a nov. gen. and was unaware of the existence of Spiroxylon Hartig. The type species of Spiroxylon Hartig is based on poorly preserved material (Kräusel and Dolianiti, 1958), but these authors should have made a neotypification rather than to propose a new name. The use of Prototaxoxylon is now well established, however, and this generic name should be proposed for conservation. [details]
