VOL. XVII. (3) FOSSIL PLANTS-FOREST OF DEAN 325 



me- these coals are the largest in the Forest, and consequently 

 the waste heaps take the form of very high hills, even ex- 

 ceeding those of the Radstock Coalfield in elevation. These 

 heaps offer abundant opportunities for plant collecting. The 

 materials are very mixed and belong to several different 

 seams but. as these coals are closely associated, and as they 

 all belong to the second Division, they may be regarded as 

 forming one large seam, the Second Division. 



I now propose to indicate the floras obtained from the 

 chief coUieries of the Second Division. 



TRAFALGAR COLLIERY 



Trafalgar CoUiery, at Drybrook Road Station, has long 

 been famous for the fossil plants obtained from its enormous 

 spoil-heaps. 



The following are the commoner species. The Calamites 

 are represented by several species of pith-casts, mcludmg 

 Calamites Suckowi, Brongn., and C. undulatus, Sternb., while 

 C. varians, Sternb., is somewhat rarer. The commonest type 

 of Calamitean fohage is Calamocladus equisetiformis (Schloth.) 

 Plate XXXVII fig 5. The fronds of Sphenoptens pneuro- 

 teroides (Boulay) Plate XXXIX., fig. 17, Neuropteris ovata, 

 Hoffm Plate XXXVII., fig. 6 and N. Scheuchzen, Hoffm., 

 Plate XXXIX., fig. 12 are frequent. The chief Pecoptends 

 are Pecopteris polymorpha (Brongn.), Plate XXXVII., fig. 3. 

 and P. Miltoni (Art.) Plate XXXVIL, fig. 2. The large seed 

 Trisonocarpus Nceggerathi (Sternb.), Plate XXXIX., fig. i5- is 

 frequent Among the Lycopods the stems of Leptdodendron 

 aculeatum. Sternb., Plate XXXIX., fig. 16, and the cones of a 

 Leptdodendron {Lepidostrobus) are not infrequent^ ^ ^^''l' 

 daitean leaf Cordaites angulosostnatus, Grand Eury, Plate 

 XXXVIII., fig. II, is abundant. 



Among the rarer plants are the great Calamitean cones 

 Macrostachya infundibuliformis (Brongn.), a very rare and in- 

 teresting plant. The less frequent fronds are Neuropteris 

 fimbriata, Lesq., and two species of Alethopteris, A.aqmhna 

 (Schloth.), Plate XXXVIIL, fig. 10, and Plate XXXIX.,
