12. Summary. 



Titbicaulis Sutcliffii xs: a new species discovered at Shore 

 in the roof of the Bullion seam, Lower Coal Measures. 



The single specimen consists of an axis with a solid 

 monostele, surrounded by numerous petioles, each with a 

 simple C-shaped meristele with the convex side toward the 

 axis. 



The petioles are small on leaving the axis, but rapidly 

 increase till they greatly exceed the axis in diameter. 



The phyllotaxy is -| ; no "axillary shoot" has been 

 observed. 



Many adventitious roots arise from petioles and axis, 

 which branch freely and generally dichotomise. 



No foliage is associated in any way, though compound 

 leaves are suggested. 



Several small annulate sporangia are associated, and 

 as the nodule is a ''roof" one this strongly indicates true 

 connection. 



The plant is closely allied to T. Solenitcs Corda, but is 

 specifically distinct. 



It appears to be one of the simpler Botryopterideae, 

 and to have no direct affinity with any living fern.
