acuminate, the secondary lanceolate or oblong and acuminate (broadest at the base) ; the ultimate divisions, 
or pinnules, oblong, obtuse, strongly and closely serrated with incurved mostly entire teeth. We can find no 
appearance of an involucre on the sori. 
9. Polypodium unidentaium; decompositum laxe tripinnatum, pinnulis pinnatifidis laiiceo- 
latis attenuatis, laciniis oblongis obtusis subfalcatis crenatis, sinubus soriferis unidentatis. 
The specimens in the Herbarium of this Polypodium hkewise appear to be hut fragments, separated from a 
much larger frond. It is remarkable for the lax distant divisions and subdivisions ; for the sori being con- 
fined to the sinuses of the notched segments j and for those sinuses having a sharp tooth beneath, or a little 
on one side of the sinus. 
10. Pol 3 ^odium crinale; decomposite pinnatum, pinnis oblongo-lanceolatis obtusissimis 
rigidis pinnatifidis glabris, laciniis ovatis obtusis, marginibus incurvis unisoriatis, rachibus 
costaque subtus paleaceo-crinitis. 
Fragments only of this very distinct Fern exist in the Collection, from which we may infer that the plant 
is at least tripinnate; the pinnules 1-2 inches long, of a rigid, almost coriaceous texture, pinnatifid: each lobe 
of the pinnule bearing a sorus of naked capsules near its superior margin. The rachides, general and partial, 
and the costa, beneath, are almost shaggy with long, spreading, subulate, or setaceous scales.

1. Nephrodium exaltatum. Sw. 
2. Nephrodium resiniferum; frondibus pinnatis, pinnis suboppositis linearibus acutis 
inciso-serratis subtus hirtis, venis resinoso-globulosis, rachi pubescente, soris submarginali- 
bus, indusiis hirtis. Kaulf. Enum. Fil. p. 237, (sub Aspid.) 
3. Nephrodium Dvbrueilianum ; frondibus fasciculatis, pinnis lanceolatis acuminatis basi 
truncatis subpinnatifidis utrinque glabris, laciniis ovato-falcatis subacutis infimis maximis, 
soris minutis biserialibus costse mediae approximatis, indusio peltato-ciliato, stipite rachique 
glabriusculis. — Polystichum Dubrueilianum. Gaud, in Freyc. Voy. p. 333. t. 9. — Aspidium 
cyatheoides ? Kaulf. Enum. Fil. p. 234. 
This is certainly the plant of Gaudichaud, above referred to ; but in our specimens the pinnae are rather 
deeply serrated than “ suhpinnatifid.” It is equally, perhaps, the A. cyatheoides of Kaulfuss; though differ- 
ing in being glabrous on the underside. 
4. Nephrodium apifolium; frondibus bipinnatis, pinnis lato-lanceolatis membranaceis 
pinnatifidis acuminatis superioribus confluentibus, laciniis oblongo-lanceolatis sinuatis sub- 
pinnatifidis glabris subciliatis supra puberulis, soris subserialibus, stipite rachique atro-pur- 
pureis nitidissimis glabris, indusiis orbicularibus sinu parvo affixis. — Aspidium apifolium ?

This appears to be a tall Fern, having a remarkably glossy pui-ple-black stipes and rachis, with membrana-
