 Brack. Ft/. U. S. Expl. Exped. p. 135 (the figures represent, 

 1, a double pseudo-involucre, one on each side the costa 

 opening next the costa and a vein on each side parallel with 

 the costa occupying the sinus or axis of the pseudo-involucre, 

 these veins each of them soriferous ; and, 2, a section with 

 a single sorus with a wmlateral involucre one lateral vein 

 wanting, but this shows no central costa). Monogramme

 each otlier, three different and very careful Pteridologists have described and 

 figured it under three different genera and with very dissimilar characters. Two 

 only have figured transverse sections of the soriferous portion. Of these three 

 the fig.ires of Brackenridge best accord with our own observations: only we have 

 not been able to detect the double line of sori in our specimens. Living speci- 

 mens are needed for ascertaining the structure in snch very minute Ferns, which 

 (io not revive after being dried, as Mosses and Ilepaticcedo -. nor are we sure that 

 the same species may not offer different modifications of sori. 



§§ Pleurogramme. — Fronds simple or forked, with lateral simple veins. — Pleu-

 scarcely creeping but short rather thick erect or ascending 

 paleaceous at the summit with rather large imbricated obtuse 

 linear ferruginous scales densely fibrous-rooted below, fronds 

 numerous tufted subsessile 2-6-8 inches long I5-2 lines 

 wide firm-coriaceous straight or falcate in the upper half 

 simple or rarely forked linear attenuated at both extremities 

 costate, veins simple oblique not extending to the margin, 

 sori linear continuous costal or from the sides of the costa 

 occupying the upper half of the frond which is more or less 

 conduplicate (so that a transverse section nearly resembles 

 the letter V) in age patent or only concave. — Teenitis, Hook.
