Laing. — List of New Zeal it ml Seaweeds. 345 



Sub-genus Aglceophyllum, J. Ag.,Sp. Aig., vol. iii., part iii., 

 p. 38. Tribe Monanthcce, J. Ag., loc. cit., p. 46: " Nitophyl- 

 lum microphyllum, Crosby Smith (Mscr.). Root an irregularly 

 creeping rhizome. Fronds clustered, many from the same 

 base, ecostate, stipitate, linear clavate, obtuse, 3-15 mm. long, 

 distantly toothed or proliferously pinnate. The principal 

 frond is often abruptly terminated, and from its apex springs 

 a secondary leaflet similar to the primary one, and proliferous 

 from the margin. Sori solitary in the terminal expanded 

 lobes, and girt round by a sterile margin, the fertile portion 

 expanding into an ovate, obovate, rotundate, or very irregular 

 lamina. The tetraspores are cruciately divided, thus appa- 

 rently distinguishing the plant from all others of the order. 

 Colour when fresh bright-red, and on drying much darker. 

 Substance membranous. This seaweed was found on a Haliotis 

 shell on the Green Island beach. It completely covered the 

 shell in a moss-like fashion. I have given it the specific name 

 Mwrophyllum, as it is, so far as my knowledge serves, the 

 smallest of the genus." 



From the above description and classification it will be 

 seen that the plant probably comes nearest to the Australian 

 N. monanthos, J. Ag. (Sp. Alg., p. 655), from which, however, 

 it differs in many ways — in the smaller size, the almost entire 

 margin, the shape of the fronds, and, above all, in the cruciately 

 divided tetraspores.

Mr. Smith has obtained a specimen of this at Riverton, 

 and also when trawling outside Otago Heads ; and I found 

 what can scarcely be anything else than a fragment of this 

 magnificent species at the Signal-station, Wellington Heads. 

 What was apparently another fragment was found by Mr. 

 Smith in the baths at St. Clair.
