Fam. GEATELOUPIACEAE. 

 Pachymenia, J. Agardh, 1876. 

 Distribution. — Cape of Good Hope, New Zealand. 



Pachymenia lusoria (Hook. f. & Harv.), J. Agardh. 



Iridaea lusoria. Hook. f. & Harv., Fl. Nov. Zel., ii, p. 252^ 1855. Pachymenia

Grateloupia (?) aucMandica, Mont. (Voy. au Pole sud, Bot. i, p. 115, tab. 110, 

 fig. 1) is a very doubtful a,nd not recently collected species. 



Fam. DUMONTIACEAE. 



DuMONTiA, Lamouroux. 



?? Dumontia filiformis, Grev. 



This plant is recorded from Campbell Island by Hooker, but is a distinctly 

 northern species. Agardh (Epicr. Florid., p. 150), writing under Grateloupia pro- 

 lifera, thinks it possible that this may have been the plant identified by Hooker as 

 D. filiformis. 



Dumontia cornuta. Hook. f. & Harv. (Fl. Antarct., vol. i, p. 189) is another not 

 recently collected plant of very doubtful identity. It is reported only from Camp- 

 bell Island. 



Fam. CORALLINACEAE. 



Literature for a proper description of the Corallinaceae, including Foslie's recent 

 papers, is not available in New Zealand, and no attempt has yet been made to identify 

 the species collected during the " Hinemoa " trip. The following species were ob- 

 tained by previous collectors : — 



CoRALLiNA (Tournefort), Lamouroux. 

 Distribution. — All seas. 



Corallina Hombronii (Mont.), J. Ag.
