EADSTOCK SERIES OF THE SOMERSET AND BRISTOL COAL FIELD. 401 



Lycopod macrospores. 



Remarks. — I have received from Mr Henry E. Hippisley a specimen of spore 

 coal from the " Slyving Vein " of the Radstock Coal Seams almost entirely 

 composed of macrospores bearing the characteristic triracliate ridge, embedded 

 in a matrix, chiefly composed of microspores. These macrospores are probably 

 similar fossils to those described as Trigonocarpus sporites by Weiss.*

 Stigmaria reticulata, Brongt., Prod., p. 87. 



Description. — Cicatrice circular or subrhomboidal, enclosed in contiguous 

 rhomboidal fields ; vascular cicatricule oval, and situated towards the upper 

 part of the cicatrice. 



Remarks. — This peculiar Lepidodendron-like Stigmaria was described by 

 Sternberg from Paulton, and placed by him in Lepidodendron. Subsequently 

 Brongniart removed it from this genus and placed it in Stigmaria, to which 

 genus the plant really belongs, notwithstanding its Lepidodendroid appearance. 

 Brongniart, however, substituted the specific name of reticulata for the older 

 one of anglica, but the original name for the species is here reinstalled. 



I have examined a good many specimens of this fossil, mostly from
