Dr. Greville. Belfast, Dr. Drummond. Miltown Malbay, Mr. Harvey. 

 If. . Winter, — Mr. Harvey's specimens of Phyllopkora rubens are some- 

 what peculiar, more than 8 inches in length, very narrow, much curled, 

 several times dichotomously divided, and in some the proliferous char- 

 acter is nearly obliterated by the primitive frond being much elongated 

 and branched ; no fructification, except nemathecia be considered such, 

 has been found upon them. 



37. Sphcerococcus. Stackh. Sphsero coccus. 



Frond cartilaginous, compressed, two-edged, linear, distich- 

 ously branched. Fructification ; mucronate capsules, containing 

 a mass of ovate, shortly pedicellate, red seeds. Grev. Alg. Brit, 

 p. 138. t. 15. — Name ; <r<p%ios&, a sphccre or globe, and -/.oxxoz, fruit, 

 from the globose fructifications. — Dr. Greville has confined the 

 Genus Sphcerococcus to the Fucus coronopifolius, Good, and 

 Woodw., and the F. crinitus, Gmel. 



1. S. coronopifolius, Ag. (Swine s cress-leaved Sphcerococcus); 

 frond cartilaginous much branched in a distichous and alternate 

 manner compressed and two-edged below nearly flat upwards, 

 the branches acute at the apex, capsules sphserical mucronate on 

 little stalks fringing the smaller branches. Gr. — Ag. Sp. Alg. 

 v. 1. p. 291. Grev. Alg. Brit.p. 138. t. 15. — Gelidium coronopif,

38. Gelidium. Lamour. Gelidium. 



Frond between cartilaginous and horny, compressed, linear, 

 more or less regularly pinnated. Fructification: — 1. capstiles 

 imbedded in the substance of the ramuli, containing a mass 

 of minute roundish seeds : — 2. ternate or otherwise compound 

 granules, in the ramuli, on distinct individuals. Grev. Alg. 

 Brit.p. 139. t. 15. — Name; from the Latin gelu, frost, whence 

 also gelatine, applicable to some of the species when boiled or 

 macerated in warm water. 



1. G. cartilagineum, Grev. (cartilaginous Gelidium); frond 

 horny nearly flat repeatedly pinnatifid w r ith horizontal mostly 

 alternate linear segments, the ultimate ones very short obtuse 

 and bearing the mucronated capsules at their apices. — Grev. 

 Alg. Brit. p. 140. — G. concatenatum, and G. versicolor, Lamour. 

 — Sph&rococcus cartilagineus, Ag. Sp. Alg. v. 1. p. 286. — Fucus 

 cartilar/ineus, Linn. — Turn. Syn. Fuc.p). 284, Hist. Fuc. t. 224.
