HOLCUS LANATUS. 



Linn^, Spec. Plant. 1485 ; Smith, Engl. Plora, i. 108. 

 Open places of Chatham-Island. 

 Evidently introduced there like into many parts of Australia. 



Arundo conspicua. 

 Forster, Prodrom. 48, accord, to J. Hook. Flor. Not. Zeal, i.- 299 ; A. aus- 

 tralis, Eich. Voy. de 1' Astrolabe, i. 121 ; A. Cunn. in Hook. Compan. to 

 the Bot. Mag. ii. 371 ; A. Kakao, Steud. Synops. Glumac. i. 194. 



Open damp places of Chatham-Island, where it is called " Toi 

 Toi" by the natives. 



The spikelets produce sometimes a fourth flower, which then is 

 imperfect. The subulate teeth at the apex of the glumella are variable 

 in length. 



It needs further investigation for ascertaining whether any of the 

 following plants are referable to A. conspicua: A. australis, Cavan. 

 in Annal. de Cienc. accord, to Eoem. et Schult. Syst. Veg. ii. 511 ; A. 

 Egmontiana, Rcem. & Schult. 1. c. ; Calamagrostis conspicua, Gmelin, 

 Syst. Nat. i. 172 ; Agrostis conspicua, Rcem. et Schult. Syst. Veg. ii. 

 364 ; Achnatherum conspicuum, Beauv. Essai, 20 ; Gynerium Zee- 

 landicum, Steud. Glumac. i. 198. 



The restriction of this Reed to New Zealand and the small ad- 

 jacent islands is a curious fact in phytogeography, when contrasted 

 with the wide distribution of A. Phragmites over the globe. The 

 latter plant is also a native of New Zealand, according to a specimen 

 brought by Dr. Haast from the Grey-River. 



AiHA C^SPITOSA.

On moist ground of Chatham-Island. 



Found also in various parts of New Zealand, for instance in the 

 Province of Canterbury, in Tasmania, and in Australia from the 

 Tattiara-country to Gipps-Land, ascending to the higher parts of 

 the Australian Alps. 



The spikelets of the Chatham-plant are rather larger than those 

 of the ordinary European state of this grass ; but somewhat smaller
