SPECIES FILICUM. 



SuBORD. VIL— SCOLOPENDRIEiE, Pr. 



Sori as in AspJeniece (Subord. VI. vol. ii. p. 76), except that 

 the involucres are arranged in pairs, opposite to each other, 

 one originating on the superior side of a veinlet, the other 

 on the inferior side of the opposite veinlet or branch. — A 

 small group, with one exception, having undivided fronds. 

 Venation free, or more or less anastomosing. 



I have ventured to unite under one genus Scolopetidrium, Sm., Antigramme, 

 Pr., Camptoaorus, Lk., and Scliaffneria, Fee. The chief distinctions depend on 

 the nature of the venation, and, certainly, in proportion as the veins anastomose, 

 the sori hecoine scattered and the involucres are not always connivent in pairs, 

 opening face to face. Metteuius excludes the group from Asplenie(B,vi\A\e Moore 

 incorporates the two.
