LYCOPODITES VANUXEMI IN BEITAIN. 561 



four new species of Lycopodites : — Lycopodites arborescens, L. 

 flexifolius, L. simplex, and L. Lacoei. 



Of these I think the last two must be regarded as doubtfully 

 referable to Lycopodites, Goldenberg ; but L. arborescens and 

 L. flexifolius are two most interesting additions to Goldenberg's 

 (not Brongniart's) genus. 



The first-mentioned author formed, or, more correctly, resus- 

 citated the Brongniartian name Lycopodites in 1855 * for a then 

 new class of Palaeozoic jdants, " true herbaceous Lycopods ; " but 

 to enable Lesquereux to include his lately-discovered species in 

 this genus, he was under the necessity of slightly modifying 

 Goldenberg's definition of Lycopodites, by adding the term " or 

 woody," to enable him to place in it plants which were evidently 

 not herbaceous, but which probably did not otherwise differ 

 from those species previously placed in Lycopodites by Golden- 

 berg. 



The generic definition of Lycopodites, Goldenberg, so emended, 

 must now read : — 



Herbaceous or woody plants with dichotomous ramification ; 

 branches with, leaves placed spirally or in verticils, leaves of the 

 same or of two different forms on the same branches ; sporangia 

 placed in the axils of the leaves or forming terminal cones. 



The addition of the term " woody " was rendered necessary on 

 account of the size of the stem of Lycopodites arborescens, Lesq., 

 which in every other character is referable to Goldenberg's genus : 

 hence the slight modification of the generic terms of Golden- 

 berg's Lycopodites, as proposed by Lesquereux, seems quite legi- 

 timate. It is also possible that Goldenberg's type-specimens 

 were only branches of a comparatively large-stemmed plant ; but 

 whether Goldenberg's plants were herbaceous or not, it is most 

 improbable that Lycopodites arborescens, Lesq., or Sigillaria 

 Vanuxemi, Goppert, were herbaceous, the latter of which I now 

 propose to include in Lycopodites, Goldenberg. 



Lycopodites {Sigillaria) Vanuxemi was first figured by Yanuxem 

 in 1842 1. He gives a description of the plant without applying 

 any name to it, but expressed the opinion that it was more 

 closely related to Lepidodendron than to any other genus. This 

 specimen was discovered in Allan's Quarry, near Oswego, New
