1. Davallia Macroeana; fronde pinnata, pinnis membranaceis glabris tlimidiato-oblongis
obtusis basi oblique truncatis cuneato-attenuatis margine superiore crenatis dentibus soriferis,
caudice longe repente.
Tins beautiful Fern has been already alluded to by Dr. Grevillc and Dr. Hooker, when describing Da-
vallia Boryana, at tab. csliii. of the leones Filicum. To tliat species oiws is very nearly allied, differing
prmcipally in its more rigid frond, aud in the upper margin of each piiuiule, which, in D . Boryana, is irregularly
cut and crenate, with few sori. Here, the crenation is very régulai-, and each tooth has its sorus at a
certain distance fi-om the margin, so that the friictifications form a line.
2. Davallia remota; frondibus tripinnatis, pinnis inferioribus oppositis remotis superioribus
alternis caudatis, pinnulis inferioribus profunde pinnatifidis, mediis laciniisque cuneatis
subtrifidis, lacinulis truncatis subbifloris, rachi supra angulata, indusiis subrotundis. Kaulf.
Enum. Fil. p . 223.
Kaulfuss well observes that the laciniæ are much broader than those of Z>. tenuifolia: tliis is the case,
especially if compared ivith the figure in Schkuhr, (tab. cxsviii. a ., sub nom. D. venustoe / ) but our specimens’
from the Mauritius, under the uame of D. tenuifolia, and, we presume, the plant of WiUdenow, are identical
with the present.
3. Davallia frondibus tripinnatis, pinnulis ovatis obtusis superiore e t antice subincisis,
laciniis dentatis, rachibus hirtis, indusiis intramarginalibus venisque subtus pilosis.

The genus Cibotium is thus defined by Kaulfuss ; “ Sori globosi submarginales contigui. Indusia car-
tilapnea globosa fornicata verticaUter oris caUosis dehiscentia, bivalvia, valvula exteriori majori.” To this,
besides his C. Chamissoi, Kaulfuss has referred the Dicksonia antárctica ; but to us the latter appears to
belong to the same author’s genus Balantium, if that he reaUy distmct 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
m the Sandwich Islands, in the year 1787, and we have long been in possession of two states of it,
presented to ns by that liberal Botanist : the one with longer and narrower pinnæ, more deeply cut in a
pinnatifid manner, the lower segments distinct, forming separate pinnules, all very glaucous beneath ; the
other with pmnæ not at all glaucous, and more coriaceous in texture, not so deeply pinnatifid, and nowhere
are the pmnæ again pinnated. Captain Beechey’s CoUection contains likewise two states, the first resembling
the glaucous variety of Mr. Menzies, but it is less glaucous -, the other not at all 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 laciniæ, which do not extend lialf way to the rachis.
