[Potypodiacea. 



ceous fronds. It is assuredly the Aspidium sinuatum of Gaudichaud, but not of Labillardiere, which has a 

 setose stipes and rachis, and tufts of hairs in the sinuses of the margins of the fronds; and is, moreover, a 

 much less divided plant. The indusia are very "unlike those of Nephrodium Hippocrepis, to which it has a 

 considerable affinity, and the colour of the stipes and rachis is different ; in the latter particular, too, it is at 

 variance with the Aspidium apifolium of Schkuhr ; but in all other respects, it seems entirely to accord 

 with that plant, whence we have been induced to adopt that name. 



5. Nephrodium squamigerum; supra decompositum tri-quadripinnatum, pinnulis ob- 

 longis obtusis pinnatifidis basi decurrentibus supra ad nervos prsecipue puberulis, stipite 

 rachibusque subtus dense squamulosis, squamis fimbriatis, soris subserialibus intra costam et 

 marginem, indusiis reniformibus tenerrimis fimbriato-ciliatis. 



The specimens in the Herbarium are but portions of a larger frond, densely divided, flaccid, the primary 

 divisions acuminated ; the upper surface glabrous, or only downy on the secondary rachides and nerves, 

 while the stipes and rachides beneath, and even the primary nerves or costae, are densely clothed with 

 copious, delicate, membranous, reticulated, and fimbriated scales. 



1. Asplenium resectum. Smith, Icon. ined. p. 72. t. 72. Forst. Prodr. n. 427. 



2. Asplenium obliquum. Sw. Syn. Fil. p. 78, et 268. Schkuhr, Fil. p. 66. t. 71. — A. luci- 

 dum ? Forst. Prodr. n. 429. 



In our specimens of this variable plant, the lower pinnae are much broader than the rest, and again pin- 

 nated with 2-4 rhomboid pinna?. 



3. Asplenium contiguum; frondibus pinnatis, pinnis lineari-lanceolatis attenuatis inciso- 

 serratis serraturis dentatis basi superiore rotundato-cuneatis subauriculatis inferiore ab- 

 scisso-attenuatis, soris contiguis cost* parallelis. Kaulf. Enum. Fil. p. 172. Gaud, in Freyc. 

 Voy. p. 321. 



That this may be a state of the following plant, we think very probable ; but we cannot agree with 

 Gaudichaud, that it is a variety of A. horridum. 



4. Asplenium filiforme; frondibus pinnatis, pinnis lanceolato-linearibus longissime 

 filiformi-attenuatis inciso-serratis serraturis adpressis subdenticulatis, infimis basi superne 

 lobato-incisis, soris contiguis costae parallelis. Kaulf. Enum. Fil. p. 172. 



5. Asplenium horridum ; frondibus pinnatis, pinnis lineari-lanceolatis attenuatis inciso- 

 lobatis, lobis oblongis truncatis crenatis, soris costae contiguis parallelis in lobis geminis, 

 stipite rachique hirsutis. Kaulf. Enum. Fil. p. 173. Gaud, in Freyc. Voy. p. 318. 



A very remarkable plant: first detected, as were the two following species, by Mr. Menzies, in the Sand- 

 wich Islands. 



6. Asplenium acuminatum <; frondibus bipinnatis glabris, pinnulis lanceolatis acuminatis 

 ihciso-pinnatifidis striato-venosis rigidis basi cuneatis lunc auriculatis, lobis dentatis, soris 

 oblique parallelis, rachi subhirsuta. 



Habit and texture of the two preceding, but constantly twice pinnated : the primary pinnae lanceolate, 

 much acuminated, 4-6 inches long, having numerous pinnules, which are from an inch to an inch and a half 

 in length, and more or less deeply inciso-pinnatifid, according to their situation upon the plant. The veins 

 are almost parallel with the costa, and hence give a striated appearance to the pinnules. 



7. Asplenium patens; frondibus triplicato-pinnatifidis, pinnis patentibus alternis, pin- 

 nulis pinnatifidis, laciniis oblongo-cuneatis apice inciso-dentatis. Kaidf. Enum. Fil. p. 175.
