be observed, that the extremities of the plant, and of the branch itself, are always wider 
than their base j their width, in the first case, being two or even three lines ; in the 
other, seldom exceeding a line and a half. It is of more rare occurrence that the frond, 
from a common centre, is branched in a stellated sort of manner: such an appearance is 
represented at tab. 84. f. 9, where the apices have also a slight disposition to be forked. 
The substance of the frond is between carnose and membranaceous, thinnest at the margin, 
where it is often slightly waved, and cut into deep and obtuse lobes of various sizes, but 
all of them large, at first sight giving the appearance of closely set, pinnated leaves j but 
the divisions never reach so far down as the nerve. These lobes are, moreover, often 
incurved, and particularly so towards the extremity of the plant (tab. 82. f. 2). The 
whole is cellulose, and the cells tolerably large, presenting, on the exterior surface, a 
beautifully reticulated appearance, with ovate areolae (tab. 83. f. f. 3. 4). 
Throughout the centre of the frond, and following the divisions of the branches to their 
very extremity, runs a very evident and broad nerve, most prominent on the underside, 
and marked on the upper side with numerous lines, as if the epidermis lay in plaits or 
folds (tab. 82. f. f. 1. 2, &c.). Sometimes it happens that the nerve is forked within the 
extremity of a simple branch, where probably the frond is about to be extended in a 
dichotomous manner, as I have already noticed in J. furcata (tab. 82. f. 1). 
The color of the whole plant is a pale-green, but that of the nerve usually paler than the 
frond ; except when the plant is dry : the base is often yellow-brown, as if in a state of 
decay. 
On the underside of this species, always upon the nerve, and closely appressed to it, are 
scattered, apparently at unequal distances, small stipulaceous scales, of an oval form, 
flatfish (tab. 82. f. f. 10. 11), and deeply, though unequally, spinoso-dentate. These 
scales must be carefully distinguished from the gemmaceous buds or tufts, found not only 
on the upper, but likewise on the underside of the plant: but they are not confined to 
the nerve, nor are they ever single or appressed to the frond. 
Male Fructification, as far as I have yet observed, upon different individuals from the Female, 
(tab. 82. f. 3.) 
Anthers two or three in the same frond, constantly imbedded in the nerve; covered, 
however, only with a very thin cuticle, and always visible, not only by the different color, 
but also by a slight swelling of the nerve where they are situated (tab. 82. f. 3). Their 
figure is elliptical, or nearly ovate : their color pale greyish. I have not been able to 
perceive any point of attachment to the cell of the frond, in which they are imbedded. 
It requires a highly-magnifying power to discover the reticulated appearance of the anther 
(tab. 82. f. 9). Within they are filled with an extremely minute, granulated substance. 
Female Fructification arising from the upper side of the frond, and towards the extremity. 
The earliest state that 1 have observed of it is represented at tab. 82. f. f. 5. 6. and tab. S4. f. 4. 
In the first of these plates are figured young pistiUa quite exposed, scattered at various 
distances upon the nerve, each of which is nearly linear, but a little swelling at the base, 
and slightly expanded at the apex, of a greyish color, and striated longitudinally with 
pale-red, and marked also with a few transverse lines. Another state of the early 
fructification is given at tab. 84. f. 4, where the pistilla are represented, equally free from 
any calyx or external covering, collected into small clusters, as they are within a 
perichaetium in every other Jungerraannia that we are acquainted with (J. Hookeri alone
