Hab. Jamaica {Swartz and othej-s), Brazil {Langsdorff,fide Fee). St. Helena, 

 Menzies, in Herb, nostr. (possibly an error in the locality). — It is remarkable 

 that Fee places this in Pleurogramme, which he distinguishes by the presence of 

 veins. 



3. M. (Eumonogramme) linearis, Klf. ; caudex filiform 

 elongated branched and densely tufted paleaceous with subu- 

 late falcate dark-brown scales, fronds copious subflaccid, 

 lineari-filiform 1-2 inches long simple slightly thickened in 

 the middle indistinctly costate veinless dilated towards the 

 apex and there for about 2-.3 lines in length conduplicate 

 soriferous in the axis, the sides forming a spurious invo- 

 lucre, sorus linear occupying the whole length of the dupli- 

 c^inxe.— Klfs. En. Fil. p. 196. Fee, Gen. Fil. p. 98. t. 9./. C.

Hab. Mauritius, Bourbon, and S. Africa, Cape of Good Hope, Miller. 



4. M. (Eumonogramme) rostrata. Hook. ; caudex thick 

 as a crow's quill ascending subpaleaceous very fibrous-root- 

 ing, fronds copious tufted firm subcoriacous 4-6 inches long 

 less than a line wide linear acuminate long-tapering down- 

 wards into a slender terete stipes i-| of an inch long, costate 

 veinless ; sterile ones uniform in width ; fertile ones swollen 

 in the upper half terete long-rostrate at the apex (and there 

 sterile) at length opening with a longitudinal fissure (the lips 

 never patent) enclosing a linear sorus of the same length as 

 the fissure formed of very numerous capsules arising from the 

 costa. (Tab. CCLXXXVIII. B.) 



Hab. Island on the Lake Omotepee, Nicaragua, C. Wright, in Ringgold and 

 Rodgers' U. S. N. Pacif. Expl. Exp. — This very distinct little Fern I owe to the 

 kindness of Mr. Eaton, who remarks, " I can assign no name to this unless it is 

 an overgrown form of Pleurogramme immersa, Fee ;" but the absence of veins, 

 setting aside other characters, would alone keep it apart from that : nor can I 

 find any of the Monogramme-gxo\i\> at all approaching it. The general form (on 

 a transverse section) of the soriferous receptacle is not unlike that of M. trichoi- 

 dea, but all else is very different. 



5. M. (Eumonogramme) sulfalcata. Hook. ; caudex slen- 

 der filiform interlaced and densely fusco-tomentose, fronds
