EQUISETALES— CALAMAII[E/E— ANNULARIA. loQ 



branches of Calamites ramosus. It is frequently difficult to distinguish it 

 from Anmilaria racUata Brong-n.^ by which name it was formerly usually 

 known. No. 7839 of the Lacoe collection, from Henry County, Missouri, 

 identified by Lesquereux as Annularia radiata, appears indistinguishable 

 from the ordinary leaves of this species. It is possible that other species of 

 Annularies represent the ultimate branches of different species of Calamites.
