A NEW SPECIES OF DEPARIA. 55 
the power of naval officers on these occasions ;—and well has Mr. 
Moore rewarded Captain -Erskine's generosity, by the discovery of seve- 
ral perfectly new and very interesting plants in that and some of the 
adjacent islands. Besides the magnificent Araucaria Cookii (Brown, 
MSS.), of which a figure will soon appear in the ‘ Botanical Magazine,’ 
three apparently new species of Dammara, and some new Ferns, have 
been the result of this voyage. We have reason to believe that Mr. 
Moore is preparing some account of the voyage in reference to the 
plants he detected ; but we trust to have his permission on the pre- 
sent occasion to dedicate one of the most remarkable of his Ferns to 
him, which he so well merits. It is a Deparia with reticulated fronds. 
I am well aware that this is a character that in the minds of some very 
able botanists would entitle the plant to constitute a new genus: but 
this is not, we have already had occasion to declare, our view of the im- 
portance of such a structure, if it be not accompanied by any other 
confirmatory character in the plant. As a subgenus or section it may 
conveniently be employed; and as the original species, D. prolifera, 
Hook., and Mathewsii, Hook., with their free veins, may be called 
Eudeparia, the section with reticulated fronds may be called Trichio- 
carpa, from the resemblance the stipitate sori bear to some species of 
Trichia.

Frond stipitate (stipes slender, dark purple, glossy), 1 foot to 13 foot ——— 
long, in outline between cordate and triangular, divided in our finest - 
specimen into seven primary pinnae, which are rather distant; the two 
lower pinnæ are again, near the rachis, pinnated ; the next pair can 
scarcely be said to be more than pinnatifid; and the terminal pinna, 
equalling one-half the length of the frond, is broadly ovate-lanceolate, | 
decurrent at the base, deeply pinnatifid, cut in its lower half into long - 
lanceolate pinnatifid segments, the upper segments gradually become 
shorter till they disappear in the acuminated point: segments always - 
acuminated. All the lowermost pinnæ and segments are lanceolate — 
and pinnatifid; the pinnz bearing the closely-placed sori on very nar- —— 
row teeth (pedicels they may be called) on both margins. The texture _
