Dadoxylon (Araucarioxylon) kerguelense sp. nov. 



In 1881 Goeppert 7 mentioned some wood received from Kergue- 

 len Island from Baron von Schleinitz, probably of Tertiary age, 

 under the name Araucarites Schleinitzi et Hookeri, but, as Gothan 8 

 points out, it is not clear whether he refers to one or two species, 

 and as there are no figures or full description Goeppert's designation 

 cannot stand.
