Oxs.—This genus is founded on a unique and rare Fern, 
as yet only known to be a native of Mount Ophir, in the 
peninsular of Malacca. On account of the sori being 
furnished with a peltate indusium I originally placed it in 
Aspideæ, but with which it has no other point of relation- 
ship. With Gleichenia (with which I now associate it), it 
not only agrees in habit but also in the character of the 
sori, differing only in the sori being compital and indusiate.

Gleichenia sp., Hook. Syn. Fil., 1865. 
Caudex slender, subfrutescent, branching, erect. Fronds 
in terminal tufts on the branches, and distant lateral ones 
_ below the tuft, linear, about 12 inches in length, pinnati- 
fidly pinnate; segments sub-rotund, about an inch in 
length, numerous, contiguous, adnate to the rachis, cori- 
aceous and concave on the under side. Veins pinnate, 2 to 
8 venules on each side, the lower forked. Sori punctiform, 
solitary on each segment near the base. Sporangia 3 to 6, 
‘mixed with numerous pilose hairs. Ring horizontal, broad. 
. Oss.— This genus is founded on a remarkable Fern, a 
native of New Caledonia, of which there are specimens in 
the Kew Herbarium, but those having arrived since the 
failure of my sight I have consequently not been able to 
examine them. It was first described as a new genus by — 
Mettenius in 1861. In the first part of the “Synopsis - 
Filicum,” published in 1865, Sir William Hooker places it — 
in Gleichenia, with which it agrees in the sori being formed `
