Lepidodendron and Lycopodites, and by the apparently strobi- 

 laceous termination of some of them. 



Salter's description of his Lepidodendron is quite definite, and 

 accords with specimens placed in my hands by Mr. Peach : — 

 " Stems half an inch broad, tapering- little, branches short ; set 

 on at an acute angle, blunt at their terminations. Leaves in 

 seven to ten rows, very short, not a line Ions; and rather spread- 

 ing than closely imbricate." These characters however, in so 

 far as they go, are rather those of the genus Lycopodites than 

 of Lepidodendron, from which this plant differs in wanting any 

 distinct leaf-bases, and in its short crowded leaves. It is to be 

 observed that they apply also to Salter's L<ycopodites Milleri, 

 and that the difference of the foliage of that species may be a 

 result merely of different state of preservation. For these reasons 

 I am disposed to place these two supposed species together, and 

 to retain for the species the name Lycopodites Milleri. It may 

 be characterized by the description above given, with merely the 

 modification that the leaves are sometimes one-third of an inch 

 long and secund. 



Decorticated branches of the above species may no doubt be 

 mistaken for Fsilophyton, but are nevertheless quite distinct 

 from it, and the slender branching dichotomous stems, with 

 terminations which, as Miller graphically states, are " like the 

 tendrils of a pea," are too characteristic to be easily mistaken, 

 even when neither fruit nor leaves appear. With reference to 

 fructification, the form of L. Milleri renders it certain that it 

 must have borne strobiles at the ends of its branchlets, or some 

 substitute for these, and not naked spore-cases like those of 

 Psilophyton. 



The remarkable fragment communicated by Sir Philip Egerton 

 to Mr. Carruthers,* belongs to a third group, and has I think 

 been quite misunderstood. I am enabled to make this statement 

 with some confidence, from the fact that the reverse or counter- 

 part of Sir Philip's specimen was in the collection of Sir Wyville 

 Thomson, and was placed by him in my hands in 1870. It was 

 noticed by me in a paper on New Devonian Plants, in the 

 Journal of the Geological Society of London in 1871, in the 

 following terms : —
