resistance of the bundle of vascular tissue originally extending 

 upwards and outwards from the interior of the plant, as compared 

 with the softer cellular tissue through which it passed, giving the 

 occasional furrowed appearance from the accidents of pressure of 

 the rocky bed in which it was petrified. Any one comparing Mr. 

 Carruthers' or my figures with that of Sternberg's Lepidodendron 

 tetrngonum {L. quadrangulare^ linger) in t. 59, fig. 2, of his 

 " Versuch einer Geognostiscli-Botanischen Darstellung der Flora 

 der Vorwelt," will find that the identity is so close, that for what 

 I have figured as a variety or species under the special name L. 

 Australe, I can only suggest the general slightly longer form of the 

 scars as possibly distinctive ; the elongation never approaches that 

 of the American true Devonian species with the smaller elongate 

 scars and central vascular cicatrix. I do not see, by the way, why 

 Geinitz's figure of the L. tetragonum in t. 3, f. 1, of his " Darstellung 

 der Flora des Hainichen-Ebersdorfer und des Floehaer Kohlenbas- 

 sins" should be supposed to be different from Sternberg's species ; 

 it shows the vascular cicatrix at the upper end.
