200 SPHENOLEPIDIUM. 



resemblance between Sphenolepidium Kurrianwm (Dunk.) and 

 species of Athrotaxis, e.g. A. laxifolia, Hook, and A. cupressoides, 

 Don. 1 Both Athrotaxis and Sequoia are placed by Eichler 2 in the 

 section Pinoide(e-Abietinece-Taxodiin(g, and it would seem highly 

 probable that the Wealden form bears a close relationship to these 

 recent genera, especially to Don's genus Athrotaxis. 



We may define Sphenolepidium as follows : Branches alternate, 

 with spirally disposed and decurrent leaves, cones small, oblong 

 and spherical, borne on short lateral branches.
