SUBANTARCTIC ISLANDS OF NEW ZEALAND.

This is the first record of the presence of this species in the southern islands. 

 Possibly it is introduced ; but I have no evidence of this, and consequently give it 

 the benefit of the doubt. 



Hook, f., PL Antarct., ii, 



Juncus planifolius, E,. Br. 



Juncus flanifolius, R. Br., Prodr., 259 (1810) : 

 545 (1847) ; Handb. N.Z. PL, 290 (1864).' 



Auckland Islands : Le Guillon (D'Urville's expedition, fide Hooker). (New 

 Zealand ; Australia and Tasmania ; Chili.) 



The inclusion of this species in the florula of the southern islands rests solely on 

 Hooker's statement in the second part of the " Plora Antarctica " (p. 545), where 

 he says, " Specimens very diminutive, but, I think, clearly referable to this species, 

 which is not uncommon throughout the islands of New Zealand." No subsequent 

 botanist has met with it, and the doubt naturally arises as to whether a large state 

 of J. antarcticus (which is very closely allied to J. planifolius) has not been mis- 

 taken for it. 



Juncus antarcticus, Hook, f 



Juncus antarcticus, Hook, f., PL Antarct., i, 79, t. 46 (1844). /. brevifolius, 

 T. Kirk in Trans. N.Z. Inst., xiv, 382 (1882). 



Auckland Islands : Adams Island ; Kirk ! Tennant ! North Arm of Carnley 

 Harbour, at sea-level ; Cockayne ! Campbell Island : Exposed summits of the 

 mountains, alt. 1,000 ft., rare ; Hooker. (New Zealand, mountain districts from 

 Ruapehu southwards.) 



In New Zealand the ordinary state of the species has the culms considerably 

 longer than the leaves, and this is also the case with Dr. Cockayne's and Mr. Tennant's 

 Auckland Island specimens. The plate in the " Plora Antarctica," however, repre- 

 sents a depauperated state (also found in New Zealand), in which the culms barely 

 exceed the leaves. Mr. Kirk's specimens are intermediate in character. 



Juncus scheuchzerioides, Gaud. 



Juncus scheuchzerioides, Gaud, in Ann. Sci. Nat., v, 100 (1825) ; Hook, f., 

 PL Antarct., i, 79 (1844). 



Auckland Islands : Marshy places, not uncommon ; Hooker, Cockayne (with 

 J. antarcticus), Aston ! Campbell Island : Near the sea ; Hooker. Antipodes 

 Island : Kirk ! (New Zealand, mountains of Central Otago ; South America, from 

 southern Argentina to Puegia and the Palkland Islands ; South Georgia ; Ker- 

 guelen Island.) 



The few specimens I have seen of this species are in poor condition, and do 

 not satisfactorily match the drawing and description given by Buchanan in the 

 " Pflanzenreich." It is possible that they may represent a distinct variety, or even 

 species, but a better series must be obtained before the question can be finally 

 decided.
