416 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Systematic Botany. 



Campbell Island : Recorded by Kirk, but not observed by any other botanist. (New 

 Zealand, common in mountain districts from the East Cape and Taupo southwards.) 

 There are no differences of importance between the Auckland Islands plant 

 and that found in the mountain districts of New Zealand. 



Cotula australis, Hook. f. 



Anacyclus australis, Sieb. ex Spreng, Syst., ii, 497 (1826). Strongylosperma 

 australe. Less., Syn. Comp., 261 (1832). Cotula australis, Hook, f., 

 Fl. Nov. Zel., i, 128 (1853). 



Campbell Island : Buchanan. See Trans. N.Z. Inst., xvi, 399. (Throughout 

 New Zealand ; east and south Australia and Tasmania ; Tristan d'Acunha.) 



Mr. Buchanan's paper on Campbell Island and its flora, quoted above, is the 

 sole authority for including this species in the florula, no subsequent botanist having 

 met with it. Its occurrence in Tristan d'Acunha, quite six thousand miles from 

 its Australian or New Zealand habitats, is one of the most puzzling instances of 

 disconnected distribution known. 



Cotula plumosa, Hook. f. 



Leftinella flumosa. Hook, f., Fl. Antarct., i, 26, t. 20 (1844). Cotula 

 plumosa. Hook, f., Handb. N.Z. Fl., 141 (1864); Phil. Trans. Roy. 

 Soc, 168, p. 20 (1879). 



Auckland and Campbell Islands : Maritime rocks and meadows near the sea, 

 abundant ; Hooker, Kirk ! and all subsequent botanists. Antipodes Island : Not 

 uncommon near the sea ; Kirk, Cockayne. Macquarie Island : Plentiful close to 

 the sea ; Fraser, Scott, Hamilton. (Kerguelen Island and the Crozets.) 



This is one of the few New Zealand plants found in Kerguelen Island which 

 does not also extend to Fuegia or the Falkland Islands. In Kerguelen Island it is 

 the only Composite, and forms immense blue-green patches where the soil is enriched 

 by the dung of the birds. It is by far the finest species of the genus. 



Cotula lanata, Hook. f. 



Leptinella lanata. Hook, f., Fl. Antarct., i, 25, t. 19 (1844). L. propinqua. 

 Hook, f., Fl. Antarct., i, 27 (1844). Cotula lanata. Hook, f., Handb. 

 N.Z. Fl., 141 (1864). 



Auckland Islands : Abundant on rocks near the sea ; Hooker and all subsequent 

 collectors. Campbell Island : Recorded by Hooker in the Handbook, but not men- 

 tioned in the " Flora Antarctica " : North-east Harbour ; Cockayne. (Endemic.) 



Varies much in the size and breadth of the leaves and the extent to which they 

 are divided, also in the degree to which the loose white cottony hairs of the young 

 stems and leaves are developed. I have seen no specimens of C. propinqua, said 

 to be intermediate between C. plumosa and C. lanata. It was originally described 

 by Hooker as a separate species, but in the Handbook he merged it with C. lanata. 

 Judging from the description, it appears to differ from both species in several im- 

 portant points, and quite possibly should be restored to specific rank.
