figure, somewhat cuneate at the base, variously cleft into oblong 

 more or less broad segments, rounded at the extremity ; spots 

 of granules small, scattered over nearly the whole frond.

Very rare. Bantry bay ; Miss Hutchins. Distinguished by its 

 broad slightly divided rounded fronds, thicker substance, and by the 

 minute dot-like spots of granules. The " Miltoivn Malbay" station, 

 given on my authority in the British Flora, is incorrect, and belongs 

 to N. Bonnemaisonii. 



4. N. Bonnemaisonii) Grev. Bonnemaisons Nitophyllum. 

 Frond shortly stipitate, flabellate or palmate, variously cleft 

 into numerous wedge-shaped segments, furnished near the base 

 with irregular vanishing nerves ; spots of granules scattered 

 over the frond. Hook. Br. Fl. v. ii. p. 287. D. Bonnemaisonii.

Shores, rather rare. Bantry bay ; Miss Hutchins. Larne ; very 

 fine ; Dr. Drummond. Youghal ; Miss Ball. Miltown Malbay and 

 Kilkee ; W. H. Harvey. Distinguished from N. punctatum by its 

 elipitate palmato-flabellate frond ; and from the following, by its dif- 

 ferent substance, and the position of the granular fructification. 



5. N. Gmelini, Grev. Marginal-fruited Nitophyllum. Frond 

 shortly stipitate, more or less flabellate, variously cleft into 

 broadly wedge-shaped segments, waved, curled, and rather 

 crisp, marked near the base with vague vanishing nerves ; spots 

 of granules linear, marginal. Hook. Br. FL v. ii. p. 288. E. 

 Bot. Suppl. 



In the sea. Bantry bay ; Miss Hutchins. Larne ; Dr. Drum- 

 mond. Kilkee ; W. H. Harvey. Fronds 2 4 inches long, roundish, 

 when fresh curled and crisped, with a rather disagreeable smell and dark 

 pink colour ; when dry, delicately membranaceous. 



6. N. laceratum, Grev. Torn Nitophyllum. Frond sessile, 

 much divided in a dichotomous manner, veiny, segments mostly 

 linear, variously cleft, waved at the margin ; spots of granules 

 oblong, either marginal or borne in distinct foliaceous marginal 

 processes. Hook. Br. Fl. v. ii. p. 288. F. laceratus. Turn. 

 Hist. t. 68. E. Bot. 1. 1067. 



Common on rocks and Algae. Dr. Drummond 1 s specimens, gathered 

 at Larne, near Belfast, are the largest and finest I have seen. The 

 veins in this species are often very highly developed. 



38. RHODOMENIA. Grev. Rhodomenia. 



Frond plane, membranaceous, fine pink or red, quite veinless, 

 sessile, or with a short stem, which expands immediately into 

 the frond. Fruct.: 1. hemispherical, scattered capsules; 

 2. minute, ternate granules, spreading over the whole or 

 some part of the frond, (not in distinct spots or sori.) Grev.
