SANDWICH ISLANDS. 
[Polypodiacea. 
1. Davallia Macrceana; fronde pinnata, pinnis membranaceis glabris dimidiato-oblongis 
obtusis basi oblique truncatis cuneato-attenuatis margine superiore crenatis dentibus sori- 
feris, caudice longe repente. 
This beautiful Fern has been akeady alluded to by Dr. GreviUe and Dr. Hooker, when describing Da- 
vallia Boryana, at tab. cxliii. of the leones Filicum. To that species ours is very nearly allied, differing 
principally in its more rigid frond, and in the upper margin of each pinnule, which, in D. Boryana, is irregu- 
larly cut and crenate, with few sori. Here, the crenation is very regular, and each tooth has its sorus at a 
certain distance from the margin, so that the fructifications form a line. 
2. Davallia remota; frondibus tripinnatis, pinnis inferioribus oppositis remotis superiori- 
bus alternis caudatis, pinnulis inferioribus profunde pinnatifidis, mediis laciniisque cuneatis 
subtrifidis, lacinulis truncatis subbifloris, rachi supra angulata, indusiis subrotundis. Kaulf. 
Enuni. Fil. p. 223. 
Kaulfuss well observes that the lacinise are much broader than those of D. tenuifolia ; this is the case, 
especially if compared with the figime in Schkuhr, (tab. cxxviii. a., sub nom. D. venustce ;) but our specimens 
from the Mamitius, under the name of D. tenuifolia, and, we presume, the plant of WiUdenow, are identical 
with the present. 
3. Davallia hirta; frondibus tripinnatis, pinnulis ovatis obtusis superiore et antice sub- 
incisis, laciniis dentatis, racliibus hirtis, indusiis intramarginalibus venisque subtus pilosis.

1. Dicksonia flaccida. Sw. Syn. Fil. p. IST. Schkuhr, Fil. t. 129. 
1. Cibotium glaucum. — Cibotium Chamissoi. Kaulf. Fnum. Fil. p. 230. t. 1. f. 11, 
[April, 1824.) — ^Pinonia splendens. Gaud, in Ann. des Sc. Nat. Dec. 1824, idem in Freyc. 
Voy. p. 369. t. 21. — Dicksonia glauca. Sm. in Rees^ Cycl. 
The genus Cibotium is thus defined by Kaulfuss ; “ Sori globosi submarginales contigui. Indusia car- 
tilaginea globosa fornicata verticaliter oris caUosis dehiscentia, bivalvia, valvula exterior! majori.” To this, 
besides his C. Chamissoi, Kaulfuss has referred the Dicksonia antarctica ; but to us the latter appears to 
belong to the same author’s genus Balantium, if that be really distinct from Cibotium. In Cibotium, the 
involucre or indusium is a distinct substance from the margin of the frond : in Balantium, the outer valve 
of the involucre is formed of the substance of the margin of the frond. — Mr. Menzies first detected this plant 
in the Sandwich Islands, in the year 1787, and we have long been in possession of two states of it, 
presented to us by that liberal Botanist : the one with longer and narrower pinnae, more deeply cut in a 
pinnatifid manner, the lower segments distinct, forming separate pinnules, aU very glaucous beneath ; — the 
other with pinn» not at all glaucous, and moi’e coriaceous in texture, not so deeply pinnatifid, and nowhere 
are the pinnae again pinnated. Captain Beechey’s Collection contains likewise two states, the first resem- 
bling the glaucous variety of Mr. Menzies, but it is less glaucous ; the other not at aU glaucous, larger in all 
its parts, particularly in the sori, which are fewer on each lacinia, and more confined to the lower part of it, 
while the pinna is pinnatifid, with broad, rounded lacinife, which do not extend half way to the rachis. 
1. Deparia prolifera. — D. Macr^i. Hook, et Grev. Ic. Fil. t. 154. — Dicksonia proli- 
fera. Kaulf. Enum. Fil. p. 225. 
The following is the character of this genus : — Deparia, Hook, et Grev. j — Sori subglobosi in dentibus 
ad margines frondis veuulas terminantes. involuemm infi’a sorum insertum, pateriforme, membranaceum, 
margine sublaceratura.
