50. CorynojMcea nmhellata, J. Ag., Till Alg. Syst., i., p. 21; 

 Harvey Gibson, Journal of Botany, June, 1893. 



51. Mcsogloia intestinalis. Fl. Nov.-Zel., p. 220. 

 Blind Bay, Auckland, Otago Harbour : Lyall. 



I have a plant collected at Dunedin by Mr. J. Crosby 

 Smith which may belong to this species, but the original 

 identification of the genus is more than open to suspicion. 



52. Leathesia difformis, L. Aresch. Phyc. Scand., p. 376. 

 French Pass : Dr. Schauinsland. 



This is probably Leathesia hcrUeyi (Fl. Nov.-Zel., p. 220). 

 The plant is common throughout the Islands. I have ob- 

 served it at various places between Half-moon Bay, Stewart 

 Island, and Mongonui. 



53. Scytothamnus australis. Fl. Nov -Zel., p. 219. 

 Everywhere plentiful on tidal rocks. The position of the 



genus is uncertain. 



Order Bncoeliacese. 



(Murray, " Introduction to Study of Seaweeds, p. 104.) 



54. Asperococcus sinuosus. Fl. Nov.-Zel., p. 219. 

 Everywhere plentiful near high-water mark. 



Order Laiuinariaceae. 



55. Adenocystis lessoni. Fl. Nov.-Zel., p. 218 ; Phycological 

 Memoirs, x. (Brit. Mus.). 



An annual, everywhere abundant between the months of 

 October and May. The best specimens, however, come from 

 the South Island. The finest I have seen were growing on 

 tidal flats, Wyckliffe Bay, Otago Peninsula. 



56. Ecklonia richardiana. Fl. Nov.-Zel., p. 218. 



This is apparently the common species of Ecklonia, wrongly 

 referred to in Hooker's Handbook as E. radiata. 



Lyttelton : B. M. L. Hawke's Bay : Colenso. Lyall's 

 Bay, Bay of Islands : Berggren. 



57. Ecklonia radiata. Fl. Nov.-Zel., p. 217. 



The occurrence of this plant in New Zealand is somewhat 

 doubtful. I have a juvenile specimen from the Bay of Islands 

 which possibly belongs to this species, and Agardh has spe- 

 cimens from the Chatham Islands which he also doubtfully 

 refers to E. radiata (De Alg. N.Z. Mar., p. 6). 



58. Ecklonia exasperata. Fl. Nov.-Zel., p. 217. 



New Zealand : D' Urville ; Cunningham ; Hooker. Island 

 Bay, Mongonui : B. M. L. 



59. Ecklonia brcvipes, J. Ag., De Alg. N.Z. Mar., p. 5. 

 Bay of Islands (very sparingly) : Berggren.
