inciso-pinnatifidis subtus rufo-tomentosis, supra rhachi stipiteque rufo-hirsutis. Presl, Reliq. 

 HcBnk. v. 1. p. 19. 



Hab. Conception. — The specimen is a solitary one, scarcely two inches high, and agreeing with Presl's 

 var. B>. in having the upper side of the frond nearly destitute of hairs.

2. P. rugulosum; frondibus tripinnatifidis, pinnulis profunde pinnatifidis oblongis, 

 laciniis 'ovatis obtusis obtuse serratis, soris solitariis submarginalibus, stipite rachibusque 

 universalibus supra canaliculatis asperis, partialibus hirtis. Kaulf. — Lahill. Nov. Holl. v. 2.

Hab. Conception. — Our specimens entirely accord with the New Holland plant figured by Labillardiere. 



3. ASPIDIUM. Br. 



1. A. subintegerrimum ; fronde lato-lanceolata bipinnata, pinnis lineari-lanceolatis attenu- 

 atis, pinnulis coriaceis ovatis subfalcatis petiolatis basi superne auriculatis mucronatis ob- 

 scure crenato-serratis summis confluentibus, inferioribus rachi parallelis subpinnatifidis 

 supra glabris subtus stipite rachique paleaceo-hirsutis. 



Stipes supra canaliculatus, hie illic punctis nigris (spinularum vestigiis?) aspera. Frons bipedalis et ultra. 

 Pinna subhorizontaliter patentes, inferiores reflexse, palmares: Pinnulm vix unciam longae, inferiores remotae, 

 superiores confertiores, superne coadunatse. Sori discreti inter costam et marginem uniseriales. Indusia 

 peltata, umbilicata, parva. 



Hab. Conception. — Very nearly allied to A. aculeatum and others of that groupe, but particularly to 

 A. stramineum, Kaulf.; — from all which it differs in the lengthened attenuated pinnae, nearly entire pinnulae, 

 of which the lower ones are remote, the lowest pair more or less lobed, or even pinnatifid, standing parallel 

 with the rachis. 



2. A. vestitum; frondibus bipinnatis, pinnis lineari-lanceolatis inferioribus deflexis, 

 pinnulis ovato-oblongis mucronatis serratis dentibus muticis basi superiori auriculatis sub- 

 tus villosis infimis superioribus longioribus oblongo-lanceolatis inciso-dentatis, stipite 

 squamis marginatis paleaceo, rachibus villoso-squamosis. Kaulf. — Sw. Syn. Fil. p. 33, et 

 254. Schkuhr, Fil. t. 43. Willd. Sp. PI. v. 5. p. 261. Kaulf. Syn. Fil. p. 241. Spreng. Syst.

Hab. Conception. 



4. BLECHNUM. Linn. 



1. B. hastatum; frondibus pinnatis, pinnis sterilibus oblongo-lanceolatis cordato-hastatis 

 subtus villosis, fertilibus lineari-lanceolatis auriculato-cordatis, auriculis mucronatis, soris 

 interruptis superiarum pinnarum continuis. Kaulf. Syn. Fil. p. 161.
