Specimens showing the leaf-sheaths. 



V. 7197. A specimen showing two twigs each with three or more 

 leaf-sheaths consisting of a pair of oval segments. The parallel 

 nervation is clearly seen. The apparent splitting of one of the 

 oval segments is here probably an accident in the preservation. 



India. 



V. 4413. A fragment of a branch showing two leaf-sheaths 

 attached to two successive nodes, 2-9 cm. apart. Each leaf-sheath 

 is split into two oval leaf like lobes, and is rather more than 5 cm. 

 in length. A number of parallel veins traverse each lobe, and these 

 are clearly contracted at the base of the sheath.

V. 4281. A fragment of a branch showing clearly the venation, 

 and the two oval lobes resulting from the splitting of the leaf- 

 sheath. The veins are parallel, contracting both at the apex and 

 base of the sheath. 



India. 



V. 7099. A small fragment of a leaf-sheath, similar to V. 4281, 

 showing the nervation clearly. 



Bardwan Coalfield. 



V. 7099#. Fairly well-preserved branch fragments, showing the 

 attachment of the leaf-sheaths to the axis, and the parallel nervation 

 of the oval lobes of the sheath.

V. 7099f. A rather faint impression of a number of branches 

 with their bilobed sheaths. 



Bardwan Coalfield. 



V. 7099/. A fairly well-preserved impression of a branch, 

 showing five nodes, and the bilobed leaf -sheaths borne at each node. 

 Some of the segments of the leaf-sheaths are more than 5 cm. 

 long. The nervation is clear, the parallel nerves contracting at 

 the base or point of application of the sheath to the node. In 

 some of the fragments of other branches, which occur on the same 

 piece of sandy shale, the nervation of the leaf- sheath appears to be 

 closer.
