CHYLOCLAJIA. 101 



partite tetraspores, immersed in the smaller branches and 

 ramuli. Name x>vho{, juice, and xxafoj, a branch. 



1. C. ovalis, Huds. ; frond filiform, irregularly dichotomous, 

 naked below, above beset with elliptical, simple (rarely elon- 

 gated and constricted) ramuli, tapering at the base; capsules 

 spherical. Grev. Alg. Brit. p. 116, t. 14; Hook. Br. Fl. \\. 

 p. 297 ; Wyatl, Alg. Danm. No. 114 ; Harv. Phyc. Brit. t. 

 cxviii. Fucus ovalis, E. Bot. t. 711. 



In the sea, on rocks and Algae. Annual. June to August. Frequent 

 on the shores of England and Ireland. Little Isles of Jura, Papa 

 Westra, Lightfoot. Fronds tufted, 2 10 inches high, cylindrical, from 

 half a line to a line in diameter, irregularly and somewhat distantly dicho- 

 tomous, naked below ; branches above more or less densely set with ellipti- 

 cal or lanceolate, clustered or scattered ramuli, 1 4 lines long, half a line 

 to a line in diameter, much attenuated at base, either obtuse or some- 

 what tapering at apex, and either simple, or contracted at intervals as if 

 jointed. Substance cartilaginous in the stem ; tender in the ramuli, which 

 are filled with a laxly gelatinous fluid. Capsules globose, with a pellucid 

 limbus sessile on the ramuli ; tetraspores imbedded in the ramuli. 



2. C. kaliformis, Good, and Woodw. ; frond sub-gelati- 

 nous, tubular, distantly constricted as if jointed, repeatedly 

 pinnate; branches whorled at the constrictions with chain- 

 like ramuli; capsules spherical, with a pellucid border.

In the sea, on rocks and other Alga?. Annual. June to September. 

 Frequent on the coasts of England, Scotland and Ireland. Fronds tufted, 

 4 12 or even 18 inches long, 1 or 2 lines in diameter; stem undivided, 

 attenuated at each extremity, and contracted at intervals of half an inch or 

 more. From the contractions spring long, simple, primary branches, simi- 

 lar to the stem, but more slender and more regularly contracted, opposite 

 or in whorls, patent, and bearing at their contractions one or more series of 

 lesser branches and ramuli, all of which taper at each end, and are more or 

 less distinctly contracted, the contractions of the ramuli being very close 

 together. Substance tender and gelatinous. Colour a fugitive pink or 

 purplish red. Capsules spherical, placed on the young branches ; tetraspores 

 in the ramuli. 



3. C. rejiexa,) Chauv. ; frond membranaceous, purple ; 

 lower branches cylindrical, slender, arched, attaching them- 

 selves by short rooting processes ; secondary branches simple, 

 mostly secund, moniliform, spindle-shaped ; ramuli few, scat- 

 tered, patent or recurved. Harv. Phyc. Brit. t. xlii. 



On rocks, near low-water mark. Annual. Summer. Very rare. Haging- 

 ton, near Ilfracombe, Miss Amelia Griffiths. Frond 23 inches high, 

 branching irregularly from the base ; the lower branches cylindrical, form.
