the whole producing numerous ciliæ from the disk as well as margin.
Ciliæ mostly simple, about two or three lines long, subulate, compressed,
h u t often branched, almost capillai-y, and half an inch or even an inch
in length. Substance rather soft and flaccid. Fructification of two
kinds ; roundish sporidia imbedded in the substance of the ciliæ, and hemispherical
small capsules, situated on some part of the ciliæ.

I trust the figure and description I have been enabled to
give of this plant, will be sufficient to remove all uncertainty
respecting its claim to rank as a distinct species. It has been
clearly ascertained by my friend Mrs G k i f f i t h s , that the
fructification is produced in midsummer; whereas that of S. ci-
liatus is well known to be in a perfect state in the middle of
winter. I had indeed an opportunity of observing this myself;
for in December and January 1827-8, I found abundance of
S. ciliatus in fructification, when the present species was just
beginning to make its appearance in a young state; and when
I left the coast in April, the plants had attained nearly their
full size, hut without shewing any fruit. Long before that period,
S. ciliatus had totally disappeared. The capsules seem
to be very rare, as I have seen only the specimen found by
Miss H i l l . Mr T u r n e r mentions a specimen of his var. S
having been also found by Mrs G r i f f i t h s . I have been
obliged to quote some of Mr T u r n e r ’s varieties doubtfully,
for it is impossible to decide with certainty without seeing the
original specimens; for after all, there are states of S. ciliatus
which come very near to S. jubatus in appearance. It is worthy
of remark, that S. ciliatus has two modes of fructification, one
of them being broad sori of imbedded sporidia, many of which
are ternate, thus rendering the plant a Delesseria.
