64. Scirpus maritimus Linn. var. fluviatilis (Benth.) Torr.. M. 141. 



From an open culvert near Government House ("R. M. L.) ; mill-dam 

 and other places (Maiden). 



New Zealand. Australia, and widely in the tropics. 



'55. Scirpus cernuus Vahl. (= S. riparus Spreng.. M. 140.) 



Watercourses, Emily Bay. and elsewhere. 

 Nearly cosmopolitan. 



66. Scirpus inundatus Poir., M. 138. 



In watercourses near the township. 

 New Zealand, Australia. 



67. Scirpus conspersus (Nees) Laing comb. uov. (— Isolepis conspersa 



Nees, E. 60.) 



Maiden, following Benth. (vii, p. 329), has identified Isolepsis conspersa 

 Nees, E. 60, with the previous species. T. conspersa is described in Endlicher 

 as having • 3 stamens, 3-5 spikelets in a head, with the glumes purple- 

 dotted, and the nut obscurely reticulated (" subtiliter punctata"). Now. 

 Scirpus inundatus Poir. has 1 stamen, 2-15 spikelets, glumes more or 

 iess stained with dark rec» brown, and the nut pale and smooth. The two 

 are obviously distinct specie;, and 1 believe that 1 have specimens of both 

 from Norfolk Island corresponding exactly to the descriptions, except that 

 in Isolepis conspersa the spikelets are almost terminal and generally solitary, 

 there being no bract, or only a short one just overtopping the spikelet. 

 I therefore propose to reinstate this species. It is perhaps endemic to 

 Norfolk Island. Probably examples of both species were collected by 

 Bauer, but not differentiated. S. conspersus is really much more closelv 

 allied to S. cernuus Vahl.. of which the late Mr. C. B. Clarke considered it 

 a form. 



Watercourses, Norfolk Island ; perhaps endemic. 



68. Carex Neesiana Endl., E. 62, M. 142. 



Not uncommon. 

 Endemic. 



69. Carex inversa R. Br., M. 143. 



Mount Pitt ; perhaps introduced . 

 New Zealand, Australia. 



Palmae. 



70. Rhopalostylis Baueri (Hook, f.) Wendl. & Drude, M. 128. (= Areca 

 sapida, E. 64.) 



Still abundant, though often felled for various purposes. 

 Endemic. Dr. Beccari has recently made the Kermadec Island plant 

 into a new species — 7?. Cheesemanii. 



Aroideae axd Musaceae. 



There are many varieties of taro on the island, known by local names. 

 Most of these have certainly been introduced — e.g., Forty's taro, Sunday 

 Island taro, &c. Maiden, however, regards Colocasia antiquorum Schott. 

 as indigenous. He quotes a passage written by Governor King in 1788.
