C. testi/i/, Pr. (Diclisoniie sp. Herb. Bras. Retj. BeroL ti. 

 118.) — This, judging from an authentic specimen received 

 from Dr. Klolzsch, is the JVoodsia iiicisa of Gill, and Hooh. 

 et Grev. Ic. Fil. t. 191. (See p. 63 of the present volume). 



C. odorata, Pr. (Aspidium odoratum, Bory), from Mauri- 

 tius. My specimen so named from Sieber, and which quite 

 agrees with the description, is doubtless a Lasilrcca. 



C. r Brasiliana, Pr. (Aspid. Brasilianum, Br.) — Name 

 only. 



C. gigantea, Pr. (Aspidium foliosum, Wall.) is Diacalpe 

 aspidioides, Bl., and of this work, p. 59. 



C. comosa, Pr. (Polypodium foliosum. Wall.), is Alsophila 

 comosa of this work, p. 53. 



C. aspidioides, Pr. (Dicksonia aspidioides, Willd. Herb.) 

 — Name only. An Diacalpe ? 



The Aspidium viridulum, Desv. Mag. Nat. Ber. 1811, p. 

 321, [Polypodium adiantifolium, Poir. Enc. v. p. 541), — the 

 Aspidium elaium, Bory [Aspid. Boryanum, Willd.), Aspid. 

 scandicinum, Willd., and Aspid. Javense, Willd., Desvaux 

 refers lo C'ystopteris, but I know not upon what authority. 



Tribe IV. LINDS^EvE. 



Sori linear, transverse, more or less elongated, interrupted or 

 continuous, marginal, uniting the apices of 2 or more free veins, 

 or of several anastomosing ones. Involucre linear, marginal, 

 double, often toothed, opening outwardly ; one formed by 

 the margin of the frond more or less scariose, the other ac- 

 cessory, thin, scariose, parallel with it or a little below it, in- 

 cluding the capsules in the sinus. — Tufted or (jenerally creep- 

 ing ferns, tropical, rarely extratropical fin the southern he- 

 misphere). Fronds varying in texture, .simple or pinnated 

 or variously divided; pinnte and -^mnnles, frequently dimidi- 

 ate. Veins dichotomously divided or pinnated or variously 

 anastomosing. (Hook. Gen. Fil. Tab. LXIII. A. Lindsoea.

Obs. — The present group, of which LhuUcpji is the type, in some 

 of its species borders too closely upon DamUia, especially where the 

 involucre is short or frequently interrupted. In its more characteris- 

 tic form, transverse, long-, linear and continuous, the distinction is easily 

 seized, and maybe described as formed of a double linear scariose margin, 

 opening outwardly, so that a transverse section represents the letter V, the
