LEPIDOrHXOIOS. 163 



Genus LEPIDOPHLOIOS, Sternberg, 1826. 

 [Flora Vorwelt, Heft iv, p. xiii.] 



Arborescent Lycopods, sterns dichotomously branched, branches 

 clothed with imbricated, scale-like leaf-cushions, bearing leaf-scars 

 at or near the summit. Leaf-cushions rhomboidal, transversely 

 elongate, smooth or keeled, upright or reflexed. Leaf-scars oval 

 or rhomboidal, transversely elongate, the median angles usually 

 rounded. Vascular print usually larger than the two lateral prints 

 of the parichnos, sometimes more or less triangular in form. 

 Leaves linear, lanceolate, uninerved. Cones of the Lepidostrobus 

 type, borne on special fructiferous branches (Hafonia), arranged 

 spirally, ? stalked. Internal structure closely similar to Lepido- 

 dendron, from which it differs by a few characters, such as the 

 crenulated outer margin of the wood. 



Lepidophliiios is a comparatively small genus, occurring in the 

 Lower and Upper Carboniferous rocks of Europe and North America, 

 and with the Glossopteris flora in South America.
