 clumsy; branches irregularly pinnate, thick, vermicular, lineari- 

 fusiform ; ramuli copious, elongated, flexuose, resembling the 

 branches. Mesoqloia vermicularis, Ag. Harv. in Hook. Br. Fl.

2. T. Giiffithsiana, Harv. Mrs. Griffiths' Trichocladia. 

 Frond slender, equal throughout; branches alternate or irregu- 

 lar, filiform, long, simple, nearly bare of ramuli. Mesogloia 

 Griffithsiana, Grev. Harv. in Hook. Br. Fl. v. ii. p. 387. 



Sea-shores, rare. Bantry bay; Miss Hutchins. 8 — 16 inches high 

 of a pale rather olive-green, becoming greener in fresh water. Branches 

 long, subsimple, covered with long colourless byssoid fibres, similar to 

 those found in Chordaria flagelliformis, a plant which this species 

 strongly resembles in habit. Capsules pyriform. 



3. T. virescens, Harv. Greenish villous Trichocladia. Frond 

 filiform, gelatinous; branches long, erecto-patent, slender, vil- 

 lous; ramuli numerous, patent, short, flexuose. obtuse. Meso-

 M. gracilis, Carm. — Berk. Alg. t. 1G. f. 2. and t. 17. f. \.) 



Sea- shores. Bantry bay ; Miss Hutchins. I have examined the 

 M. gracilis of Captain Carmichae), and do not consider it specifically

 Mr. Berkeley's M. affinis, yet, judging- from the figure and description 

 of that author, I can consider it but as the young of this species. 



26. Corynephora. Ag. Corynephora. 



Frond globose or lobed, carnoso-coriaceous, hollow (not filled 

 with gelatine), composed of articulated dichotomous fila- 

 ments, fasciculated at the apices, and issuing from a central 

 point. Fruct.; oval capsules, seated in the terminal fasciculi. — 

 Name ; tcopovn, a club, and (fiopew, to bear ; the apices of the 

 filaments, which constitute the periphery, are clavate.

 t. 25. (imperfect.) 



On rocks in the sea, very common. Frond carnose, forming many 

 hollow lobed tubers, and spreading over a large space, olive-brown.
