40 FOSSIL PLANTS. 



of which Schimper correctly unites with Calamodadus equisetiformif . 

 The variety of Calamodadus (Asterophi/llites) equisetiformis figured by Germar 

 (Isis, p. 428, pi. ii., fig. 3, 1837), seems identical with the figure of Bechera 

 grandis, given by Sternberg (Vers. pi. xlix. fig. 1). I think it extremely pro- 

 bable that under Bechera grandis there is included only the smaller branchlets 

 of Calamodadus equisetiformis. In the figures of the latter plant given 

 by Germar (Vers. v. Wettin u. Lobejun, pi. viii.), we see some small 

 branchlets which, if separated from their parent stem, are indistinguishable 

 from some of the figures which are placed under Calamodadus grandis. In 

 the meantime, however, I have treated Calamodadus equisetiformis and Cala- 

 modadus grandis as distinct. Calamodadus (Asterophyllites) rigidus is also, 

 perhaps, only the larger stems of Calamodadus equisetiformis. On some very 

 fine examples of this last-mentioned plant, from the Eadstock Coal Field, in 

 the collections of the Bath Eoyal Literary and Scientific Institution, and 

 Mr. J. McMurtrie, F.G.S., of Radstock, the leaves on the stem which 

 supports the lateral foliage branchlets, in their form and arrangement, appear 

 indistinguishable from figures of Calamodadus rigidus. Some specimens 

 similar in character to those mentioned above have been figured by several 

 authors, and one might almost name the lateral branchlets Calamodadus 

 equisetiformis, and their supporting stem Calamodadus rigidus.
