T he form of the frond is lanceolate, sub-pinnate, with numerous
linear parallel horizontal pinnæ—about fifty-five pairs of pinnæ
on a frond ten inches in length.
The frond, which is lateral, is articulated on a creeping rh izoma.
T h e bottom h a lf of the frond is equal in width, after
which it g radually tapers to a point.
Stipes and rachis black, and covered with small thin scales.
L ength of frond varying from six to ten inches; colour a
delicate pale green. I n one, ten inches and a h a lf in length,
only two inches are n ak ed ; width of frond three inches and a
quarter.
Sori uniserial, and occupying the up p e r portion, and sometimes
the whole of the fro n d ; colour golden yellow', situated
near the edge of the frond. On a large pinna th e re are about
th irty pairs of sori.
I have v entured to include P . plumosum, of P re sl, as one of
th e synonymes of P . p lum u la , from the similarity of the fronds ;
it does n o t appear to he anywhere described, consequently it
has been considered as a misprint.
My thanks are due to Mr. Sim, of the P o o t’s Cray N u rse ry ,
K e n t, and to Messrs. Eollisson, of Tooting, ne a r L ondon, for
plants of this species, and to Air. Henderson, of Wentworth,
for fronds.
