VOL. XVII. (3) FOSSIL PLANTS— FOREST OF DEAN 329 



Morris, the Manager of the Lydbrook ColUery, noticed when 

 working this seam that a small bed of shale occurred about 

 3 feet above the seam. He very kindly at once communicated 

 with me, and saved as much of the plant-bearing material as 

 possible. When I arrived a few days later, I was able to 

 collect a number of species from it. I would express my sincere 

 thanks to Mr Morris for the alertness with which he made such 

 good use of this unique opportunity, and for his personal kind-

The following is a list of the species obtained, many of

 Annularia stellata {Schloth.) 

 Calamostachys tuberculata (Sternb.)

The Horizon of the Productive Beds of the 

 Forest of Dean 



If the floras of the three divisions of the Productive 

 Measures of the Forest of Dean are compared, it will be found 

 that they are to a large extent identical, and undoubtedly 

 they all belong to. the same palseobotanical horizon, which is 

 the Upper Coal Measures. In all, 44 species are known from 

 the Forest, none of which are new to Britain, though some of 

 them, such as Sigillaria trigona, Sternb., and 5. Brardi, var. 

 denudata, Goepp., are very rare in other coalfields. There is 

 a close correspondence with the Upper Coal Measures (Rad- 

 stock and Farrington Series) of Radstock, and with the Upper 

 Coal Measures of Bristol. These Measures yield the most
