MESOZOIC PLANTS PERU 51 



Genus FiuciTES Schlotheim 

 Filicitcs ellcnsis Sal f eld 



I : ilicites (Alethopterisf) ellcnsis Salfeld, Gesell. Erdkunde Leip- 

 zig, Bd. 7, p. 214, pi. 3, figs, i, 2, 1911. 



It is impossible from either the description or figures of 

 this form to get any idea of its relationship. It came from 

 Huallanca in the Department of Huanuco, and probably 

 represents Cladophlebis or Matonidium. 



Genus CLADOPHLEBIS Brongniart 

 Cladophlebis sp. Salfeld 



Cladophlebis sp. cf. Coniopteris arguta L & H Salfeld, Gesell. 

 Erdkunde Leipzig, Bd. 7, p. 214, pi. 3, fig. 4, IQH- 



This fragment, which Salfeld compared with Coniopteris, 

 does not appear to possess decisive characters, at least these 

 cannot be made out from the published account or figure. 

 Material was from Huallanca, Dept. Huanuco. 



Salfeld also recorded two Sphenopteris sp. one of which 

 he compared with Coniopteris and the other with Cladoph- 

 lebis. Since neither are described or figured they are best 

 ignored. 



Genus SPHENOPTERIS Brongniart 

 Sphenopteris Berthoni Zeiller 



Sphenopteris Berthoni Zeiller, Revue Gen. Bot, tome 25 bis, p. 

 5, pi. 20, figs, i, la, 1914. 



This form is fuHy described and figured by Zeiller, but its 

 precise botanical position is uncertain. Although depreci- 

 ating the use of the Paleozoic form-genus Sphenopteris for 

 entirely unrelated Mesozoic ferns, no better disposition can 

 be made of it. It came from Caleta del Paraiso on the 

 Island of San Lorenzo, but is not contained in my collections 

 from that locality. It is somewhat suggestive of the genus 

 Acrostichopteris Fontaine, which is a common element in the 

 Potomac group of the eastern United States.
