CARBONIFEROUS LYCOPODS AND SPHENOPHYLLS. 35 



were subsequently placed by him in Lycopodites} In the "Coal 

 Flora" some additional species of Lycopodites are described. His 

 Lycopodites (Selaginites) uncinatus" is a circinately-coiled fern, 

 and referable to Spiropteris. Schimper. His Lycopodites aster- 

 ophyllitcefolius 3 may possibly be a Lepidodendroid branchlet. 

 Of those described in Vol. III. of the Coal Flora (1884) some seem 

 to be very doubtful members of this genus. His Lycopodites 

 arborescens* much resembles the branchlets of Bothrodendron, but 

 I do not speak with any certainty on this point, as it is 

 impossible to express any critical opinion without examining the 

 original specimen. Of his Lycopodites simplex^ and Lycopodites 

 Lacoei 6 there seems no evidence, as far as one can judge from the 

 data given, for including them in Lycopodites. Of all the species 

 described by Lesquereux the one which appears to have most 

 claim for inclusion in this genus is his Lycopodites Jlexifolius. 7 



Sir William Dawson has referred a few small fossils from the 

 Devonian of Canada to Lycopodites, but the published descriptions 

 and figures do not afford much evidence in support of the position 

 assigned to them. 



Two small stems from Autun, France, showing their internal 

 organisation, were originally described as Lycopodium punctatum, 

 B. Renault, and Lycopodium Renaidtii, Ad. Brongt., 8 but 

 Renault has lately removed these from Lycopodium and placed 

 them in the genus Heterangium, where they find their true 

 position. 



I have gone somewhat fully into the genus Lycopodites, Brongt., 

 as it is an extremely interesting one and one which might be 

 easily passed over. True members of it seem to be rare, but
