H ab. Attached to marine rocks in small pools left by the tide. Black Rocks
at Leith, in company with Mr W a l k e r A r n o t t . March. Also, but
sparingly, between Newhaven and Caroline Park.
Tufted, lax, about half an inch high, flexible, growing upright in the water.
Fronds filiform, continuous, about as thick as a hog’s bristle, yellowish or
olive green, tenacious, simple at the base, b u t soon becoming branched,
and often somewhat fasciculated, summits incrassated, of a darker colour,
often shortly forked, and furnished with a semipellucid apiculus. The
whole frond is filled with a transparent gelatinous mass, containing cylindrical
granules, which escape by incision and slight pressure.
This singular plant belongs to a very puzzling genus, one
species of which is well known in this country, under the name
of Conferva fx tid a , and is figured somewhat inaccurately by
D i l l w y n . A g a r d h describes two other species, paradoxa
and chthonoplastes, tbe latter of which is certainly not a true
Gloionema. L y n g b y e , in the place of this genus has substituted
one of his own; and, under Bangia, has, in addition to
