two sori, Mr. Brackenridge has been misled by the artist, who has re- 

 presented sporangia as arising from a filiform receptacle in the axis of 

 the supposed indusia, at a distance from the costa ; hence his character : 



Vena simplices, rectse, liberse, intramarginales, nempe unica inter 

 costam subtus prominentem et margines frondis angusto-linearis ^qui- 

 distans, receptacidum sporangiferum continvum efFormans." This we

couverte par deux membranes qui se touchent vers la partie moyenne 



de la ligne, et s'ouvrent de dedans en dehors. Lorsque ces membranes 



sont oiivertes, la ligne formee par les capsules semble etre cachee dans 



1 epaisseur de la feuille/' In other words, the sorus is, in its younger 



state,. sunk between the somewhat projecting margin of the adjacent 



portion of the frond, as hi several nudisorous Perns, for example Antro- 



pJiyum (see Hook. Gen. Fil. tab. CIX.^. f. 3, and Tamopieru, Hook. 



1. c. tab. LXXVI.5. f. 3). In a more advanced state these raised edges 



are concealed by the spreading of the sporangia; heuce Tee, "Les 



deux cotes de la lame se creusenl dans --la Pleurogramme immersa^ pour 



recevoir les sporaiiges, et le mesoneure qui fait office de receptacle 



s'epaissit legerement au point fructifere." — The plant is a true Pleuro-
