23. V. plantaginea, Bory ; " fronds linear-lanceolate ensi- 

 form acuminate subtranslucent soft and subpapyraccous pale 

 vinous colour when dry tapering below into a depressed plane 

 base, sori subendophyllous brown-snuff colour, sulcus dilated, 

 caudex as thick as a pigeon's quill, the scales narrow cancel- 

 late long setaceous at the apex lanceolate subentire at the 

 margin." Fee. — Bory, It'm.'n. p. ^25. Sw. Syn. Fit. p. 110.

 represented, at letter B. a, at variance with Fee's remark, 

 " privee absolument de mesoneure"). 



Hal). " Bourbon and Mauritius, Bon/ ; also in the Marianne Islands." — " Total 

 length of the frond 20-23 centini., 4-G uiillini. wide. Near V. zoslercpfolia, 

 hut smaller, and in drying it becomes of a decided straw-colour. Other dif- 

 ferences exist in the form of the fronds and their consistence ; the scales, 

 too, are not exactly similar. Its affinity with V. rigida is more easily shown, 

 which latter is rigid-coriaceous, opaque, and brown when dry ; the scales differ in 

 form, and the position of the sori is not quite identical." And thus on account of 

 these slight differences. Dr. Greville's and my figure V. plantaginea, \n Ic. Fil. (so 

 much praised by M. Fee), though done from an authentic specimen derived 

 from M. Uory, is pronounced not to be Dory's plant, and is united to V. rigida ! 

 To this union I offer no objection ; so far from it, we declared that we did not 

 see how the species could be satisfactorily distinguished from V. elongata, Sw., 

 and V. emiformis, now justly considered the same as rigida. 



24. V. anodontolepis. Fee; "fronds elongated narrow de- 

 pressed and scarcely narrower at the base, sori marginal sub- 

 endophyllous rather broad brown-snuff colour continuous, 

 caudex creeping, scales cinereous lanceolate very long acumi- 

 nate entire at the margin." Fee, Vittar. p. 23. t. 4./. 3. V. 

 isoetifolia, Willd. Herb. Berol. {Fee). 



lliib. Graham, Marianne Islands, Chami.i.io. — The figure represents tiie fronds 

 unusually slender, the longest 13 inches long and 1 line wide, the siiortest 4-5 

 inches long, but broader upwards (probably sterile), so as to be there 2 lines 

 broad. " Distinct from V. isoetifolia in habit, in the scales, and in the form of 

 the sporangiasters, which are cyathiform and not claviform." 



(M. Foe gives the following additional species in his 7me Mem. Foug. Nouv. p. 

 26. t. 20. f. 1, hut I do not know its proper place in the above enumeration: — 

 " V. remota. Fee; fronds linear-lanceolate attenuated at the base and the apex 

 slightly curved acuminate fascicled, petioles plane flexuose rufesccnt, costa con- 

 tinuous broad at the base and brown, margins with a few thick teeth, sori super- 

 ficial brown distant from the margin, cajjsules oval, annulus with 20-22 articu- 

 lations, spores large reniform, sporangiasters scyphuliform." Fee. llab. New 

 Granada, Schlim,n. 611. — " Rcsemh\es Pleropsis angtcstifolia, Desv., but Ihe veins 

 are those of Vittaria.'")
