RADSTOCK SERIES OF THE SOMERSET AND BRISTOL COAL FIELD. 395 



Lepidodendra which agree in the form of their leaf-scars with Presl's 

 B. rhombica, angulata, and quadrata. On one example, about 7 inches long, 

 the lower leaf-scars are B. quadrata ; about half-way up the stem they assume 

 the shape of the leaf-scars of B. angulata, and towards the top of the specimen 

 the scars assume the ordinary Lepidodendroid form. I do not regard L. rhom- 

 bicum as a true species, but think it probably includes only peculiar conditions 

 of the leaf-scars of several species of Lepidodendra. The bolsters never seem 

 to show any clear traces of the vascular cicatrice or cicatricules. 

 Locality : — Upper Conygre Pit.
