In Britain I have observed three species of Lycojwdiles, 

 exclusive of Lycopodltes Vaimxenii, Gopp. sp., which I now 

 remove from Lycopodites and place in a new genus, Archceo- 

 siglllaria. 



The following are the British members of Lycopodites : — ' 



Lycopodites Gutbieri, Goppert.

Proc. Roy. Phys. Soc. Edln., Vol. XIT., p. 254. 

 Description. — Plant dividing by dichotomous ramification. 

 „ Leaves dimorphic. The larger lateral 



leaves lanceolate, slightly sickle- 

 shaped, single-nerved, and spreading. 

 The two rows on the ventral surface 

 much smaller and closely adpressed 

 to the stem. Fructification in the 

 form of long narrow terminal cones. 

 Remarks. — This species is only 

 known to me as British by two small
