Laing — List of New Zealand Seaiveeds. 347 



I ventured (loci cit.) to identify a species of Delesseria with 

 D. crassinervia. Agardh (Sp. Alg., vol. iii., part iii., p. 217) 

 animadverts on my criticism of his treatment of the species 

 D. crassinervia, and states that he is altogether doubtful as 

 to the identity of my plant. He suggests again that D. crassi- 

 nervia, Mont., may be Nitophyllum endivicefolium. Whether 

 my plant is identical with that of Montagne may perhaps be 

 left an open question in the absence of his type specimens, 

 but it seems to me to agree better with his description than 

 any other species which I know does. Agardh (Epicr.,p. 496) 

 points out that D. crassinervia. Hook, and Harv., is in part 

 D. epiglossitm, J. Ag., and again refers to this in Sp. Alg., 

 vol. iii., part iii., p. 218; but my plant is certainly quite dis- 

 tinct from D. epiglossum. Further, I have a specimen of A". 

 endivicefolium sent me from Victoria by Mr. H. T. Tisdall, and 

 this is certainly also distinct from D. crassinervia. It is pos- 

 sible my species may be Apoglossam montagneanum, J. Ag., of 

 which I have seen no specimen ; but, judging from the pub- 

 lished descriptions, it differs considerably also from this. 

 Since describing it previously I have observed the cystocarps 

 but not examined them microscopically ; they are solitary, and 

 placed on the veins of the leaflets. It must be admitted that 

 my photographs as they appear in the "Transactions of the 

 New Zealand Institute " (vol. xxix.) perhaps justify Agardh's 

 criticism of them.

Major Eeinbold thus names a plant sent from Lyall Bay 

 by myself, but I can find no published description of it in the 

 literature accessible to me. 



279. Batrachospermum sp. 



B. moniliforme, Both., is described as occurring in New 

 Zealand (Fl. Nov.-Zel, p. 261) in the fresh-water streams of 

 Canterbury. I have specimens collected in a tributary of the 

 Avon crossing the Ham Road by Robert Brown and myself, 

 but the species is distinct from the European moniliforme, 

 and possibly new
