50 CATALOGUE OF FOSSIL PLANTS 



in this catalogue as the foliage, and the Aster ophyllites tubercu- 

 loma, Sternb. and L. et H., as the fructification of C. canncuformie. 

 From the length of the stems connected with these cones or 

 spikes it seems very probable that they grew on a fertile stem, 

 at the top of which the spikes were arranged in a panicle. 



C. cannceformis is the largest and most striking species found 

 in this coal-field, but none of the finest and best characterized 

 specimens have yet been figured. Though several fine speci- 

 mens were found in the Hutton Collection, ISos. 53-56, yet the 

 only specimen figured by Lindley and Hutton was a very small, 

 irregular, and badly-preserved specimen from the Collection of 

 Natural History Society, the Type of which, C. cannceformis, 

 F. F., pi. 79, is still preserved in the Museum. The octavo size 

 of the Fossil Flora would, probably, prevent the authors from 

 figuring very large specimens.

74. — Calamites approximatus, L. et H. Type SPECIMEN, F.F., pi. 77. 

 Specimen twelve inches long, with numerous narrow joints 

 about half an inch long. The longitudinal ribs very fine 

 and distinct, and sharply defined on the internodes. A thin 

 layer of carbonaceous matter shewn here and there, through 

 which the joints and ribs are not so distinctly indicated. One 

 or two tubercles are visible on some of the joints. 

 Loc. — Shale above the Bensham Seam, Jarrow. (H. C. 12). 



75. — This specimen also shews a central, narrow-jointed, finely-fur- 

 rowed axis, with smooth, wide, lateral expansion of the inner 

 surface of the cortex on one side. Very slight indications of 

 the joints of the axis shewn on the cortical covering, which is 

 smooth and finely striated, and not furrowed, as in Calamite 

 stems. This fragment is seven inches long, and has seventeen 

 internodes, but no tubercles are visible at the joints. 

 Loc— Shale above the Bensham Seam, Jarrow. (H. C. 8).
