“ This beautiful species differs from tbe Spermosira litorea,
Kiitz., figured in [our] Plate CXIII., in its spores being not at
all compressed, and its ordinary cells much longer compared with
their width. The membranous sheath investing tbe filament is
witb difficulty seen, and the plant bears considerable resemblance
to some species of Sphmrozyga. The curved filaments and spherical
spores render it not very unlike Monormia intricata. Berk.,
from which it is, however, perfectly distinct”—Thw. MS.*

* I am indebted to my friend G. H. K. Thwaites, Esq., of Bristol, for the
drawings copied in Plate CLXXIII., and the accompanying descriptive characters.
I have also to return him my thanks for the honour he has done me in naming
the Spermosira ; but especially for the hearty expressions which accompanied the
“p a ten ts Writing to congratulate me on a recent appointment, after the
kindest expressions, he concludes by saying, “ Do let me, in honour of the occasion,
call the beautiful new Spermosira, of which I have just sent you a sketch,
S. Harveyana, and thus pay the first tribute of respect, of this kind, to you in
your new capacity.”
