sphserical on very short peduncles scattered over the disk of the
frond.— Grev. Alg. Brit. 1. 127. Sph&rococcus mammiL, Ag. Sp.

2. C. crispus, Lyngb. (curled Chondrus) ; frond flat nerveless
dichotomous often curled the segments subcuneate, capsules
hemispherical occupying the disk on one side of the frond, and
producing a depression on the opposke side.— Grev. Alg. Brit,

Rocky shores, abundant. If.. Spring.— Variable as is this species in
the length of its fronds, from 2 or 3 to 10 or 12 inches, in the degree of
ramification, and in the relative breadth of the segments, yet the experienced
eye will not find it difficult to recognise it. Mr. Turner enumerates
the following vars.—/3. virens ; frond submembranaceous,
branches dilated upwards, flattish, extreme segments long and acumin-
ated. Turn.— y. stellatus ; frond submembranaceous, branches dilated
upwards, divided at their apices into very numerous clustered short
laciniae. Turn.—S. cequalis ; frond cartilaginous, thick, all the branches
equal, linear, the extreme segments obtuse. Turn.— %, filiformis ; frond
cartilaginous, subcylindrical, branches nearly linear, apices long and
acuminated. Turn.— £. patens ; frond subcartilaginous, channelled on
one side, dichotomous, angles of the dichotomies patent. Turn.— *?. lacerus,
frond cartilaginous compressed, apices very narrow, elongated,
branched. Turn.—3. Sarniensis ; frond between coriaceous and cartilaginous,
branches slightly channelled on one side, dilated upwards,
apices rounded and emarginate. Turn.— i. planus ; frond subcoriaceous,
flat, wide, branches linear, apices obtuse. Turn.— x. geniculatus
frond cartilaginous, compressed, branches nearly linear, tubercles subglobose,
black, frond bent, and often broken at the tubercles. Turn.—
Chondrus crispus has been extensively collected on the coasts of Ireland,
washed and bleached and employed for making blanc-mange, and for
other purposes in lieu of Isinglass. It was at one time sold by the pea-
' santry at 2s. per pound ; but now that it is found to be so common, its
value is much reduced.
3. C. membranifolius, Grev. (membranous-leaved Chondrus);
stipes cylindrical filiform branched the branches expanding into
subcuneate membranaceo-cartilaginous two-lobed or dichotomous
segments, capsules ovate shortly pedunculated arising from
the stipes.— Grev. Alg. Brit. p. 131. Sphcerococcus membranif,
