130 CATALOGUE OF FOSSIL PLANTS 



Budding part of a stem, nearly five inches long and three- 

 quarters wide, ending in a knob of leaf -scars ; the scars or 

 cushions rather indistinct, of an irregular, sub-triangular 

 shape, tapering downwards till lost in the stem, on which 

 they are indistinct and indicated by depressions only. They 

 appear to have been spirally arranged from right to left up- 

 wards. Indistinct traces of fine parallel lines on the lower 

 portion of the stem. Hutton label, " Jarrow, B." 

 Loc. — Shale above the Bensham Seam, Jarrow. (H. C. 564). 



250. (Lebour, 111. Foss. Pits., pi. 49). Type. 



Portion of a compressed stem, an inch or inch and a quarter 

 wide, with numerous raised sub-triangular or inverted cone- 

 shaped scars or cushions, more distinct than in the preceding 

 and on an older stem. The surface covered with numerous 

 small parallel lines. Scars arranged obliquely across the stem. 

 Loc— Shale above the Bensham Seam, Jarrow. (H. C. 5C5). 



Remarks. — The annexed Woodcut Kb. 1 will give a better 

 idea of the appearance of this stem than the Hutton drawing, 

 F. P., Plate 95, and will also enable anyone to correlate it with 

 the other specimens enumerated above. Though it bears some 

 resemblance to a rhizome or aerial fern-stem, the shape of the 

 leaf-scars and the longitudinal striation of the stem, and its close 

 resemblance to Nos. 249, 250, prevent that opinion being adopted. 



The "Woodcut ~No. 8 represents the upper part of a larger stem, 

 on which the imperfectly preserved leaf-scars are similar in shape 

 and arrangement, except at the apical or growing part of the 

 stem, where these scars become crowded. No. 250, figured in 

 the Illustration of Fossil Plants, has the leaf-cushions or scars 

 more distinctly preserved. These specimens seem to be closely 

 related to Cordaites.
