w . s. Hore, who had the good fortune about the same time to
discover a new species {G. Devoniensis) of this charming genus,
which is already figured in our first volume. I delayed the publication
of the present novelty in the hope that its fructification
might be detected on British specimens ; but this hope having
hitherto been disappointed, I do not wish further to delay introducing
so interesting a plant to British botanists, although my
figure wants a representation of the fruit. I could certainly have
figured fruit from an exotic specimen, had I thought it expedient
to do so. The favellce resemble those of G. setacea, but are
raised on much shorter peduncles
From G. setacea this plant may, at once, be known by its
larger size, its comparatively shorter joints, and more lubricous
substance ; but especially by the very obtuse, cylindrical, upper
ramuli, which do not taper to a point, but are of equal diameter
throughout. From G. corallina, which in many respects it
resembles, its cylindrical articulations and différent inflorescence
distinguish it.
G. secundiflora, though first noticed as a variety by Bonnemaison,
was not well understood until the younger Agardh
pointed out its characters, and clearly distinguished it from G.
setacea and G. corallina, to one or other of which it had formerly
been referred. It is one of the most common of the genus in
the Mediterranean, from several parts of which sea I have received
specimens. It occurs less commonly on the coasts of France
and Spain, and reaches its northern limit on the coast of England,
in the same locality that produces the equally southern Stenogramme
and Carpomitra. Dr. Hooker brought from the Falkland
Islands specimens which we at first referred to this species ;
but which, as they offer some points of difference, we now regard,
provisionally, as a distinct species {G. antárctico).
