FITTONIA. 133 



V. 2238. PL IX. Fig. 6. 



18cm. in length, 10cm. broad. An impression of part of the 

 lateral surface of a cycadean stem, covered with a carbonaceous 

 layer. The petiole bases are shown with unusual definition, and 

 the form of the surface of articulation is particularly clearly 

 marked. The swollen portion or cushion below the petiole scar 

 presents a fairly close resemblance to some forms of Sigillaria 

 Brardii, Brong., with its similarly situated leaf-scar, which 

 agrees closely in shape with that of Fittonia. The petiole base 

 or cushion has a length of l'7cm. The form of the leaf-scar 

 is practically identical with that of the cleanly-cut end of the 

 frond of Otozamites Gbppertianm as figured in PI. I- Fig. 2. 

 Cf. Fittonia squamata, Carr., 1 and F. insignis, Sap. 2 ; the present 

 species differs from these in the smaller size of the leaf base and 

 in their much more regular and uniform arrangement on the 

 stem. Ecclesbourne. Rufford Coll. 



V. 2121. 77 cm. long, 8-9 cm. broad. Here again the surface 

 of the stem has been carbonized, and the petiole bases present 

 a similar appearance to those in V. 2238, but are rather less 

 perfectly preserved. The comparatively long and narrow form of 

 the leaf base is clearly shown. Ecclesbourne. Rufford Coll. 



V. 2244. 35 cm. long. Probably this may be referred to 

 Fittonia Ruffordi, but the petiole bases are much less clearly 

 preserved. In all the specimens the characteristic feature is the 

 great length as compared with the breadth of the petiole bases.
