418 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Systematic Botany. 



A remarkably distinct species, not closely allied to any of the New Zealand 

 forms. Kirk compares it with the Fuegian S. candicans, and no doubt there is a 

 resemblance in the inflorescence and discoid heads ; but S. candicans has ovate 

 leaves with crenate toothed margins, widely different in appearance to the deeply 

 pinnatifid leaves of S. antipodus. 



The paucity of species of Senecio in the New Zealand subantarctic islands is 

 a very remarkable fact, of which no adequate explanation has yet been offered. 

 In Fuegia, a large portion of which lies in the same latitude as the Auckland Islands, 

 no less than thirty-three species are recorded in the most recent enumeration, that 

 given by Wildeman in the " Voyage of the ' Belgica.' " New Zealand contains 

 thirty ; and Tasmania fourteen. With the genus so well developed in the nearest 

 large land-masses, its almost total absence in the islands to the south of New Zealand 

 is one of the most striking peculiarities of their flora, both as compared with that of 

 New Zealand and with that of subantarctic America. 



Senecio Stewartiae, Armstr. 



Senecio Stewartiae, Armstr. in Trans. N.Z. Inst., xiii, 339 (1881). S. Muelleri, 

 T. Kirk in Trans. N.Z. Inst., xv, 360 (1883). 



The Snares : Not uncommon ; Kirk ! Chapman ! and all subsequent collectors. 

 (Herekopere Island, in Foveaux Strait.) 



A very handsome species, Its nearest ally is doubtless the Chatham Island 

 S. Huntii, from which it differs in the broader more acuminate leaves, with much 

 white tomentum beneath, and in the narrow contorted ray-florets. The restricted 

 geographical range of many species of Senecio has often been remarked ; but hardly 

 any instance is more striking than that of the present species, which is confined to 

 two small rocky islets not much more than a square mile in area. 



Taraxacum officinale, Wigg. 



Taraxacum officinale, Wigg., Prim. Fl. Holsat., 56. T. dens-lennis. Desf., 

 Fl. Atlant., ii, 228. 



Campbell Island : Not plentiful ; E. M. Laing ! (Throughout the temperate 

 regions of both hemispheres.) 



Mr. Laing is the first to collect this in the southern islands. It is possible 

 that it may be naturalised ; but his specimens belong to the small mountain form 

 known to be indigenous in New Zealand, having been collected by Banks and Solander, 

 and not to the larger state common in pastures and cultivated soil, which is certainly 

 an importation. 



Sonchus asper, Hill. 



Sonchus asfer. Hill, Herb. Brit., i, 47. S. oleraceus, Linn., var. B, Hook, f., 

 Fl. Nov. Zel., i, 153 (1853). 



The Snares : Kirk. Auckland Islands : Dr. Koettlitz. Campbell Island : Near 

 the shore ; E. M. Laing ! Antipodes Island : Kirk. (Cosmopolitan.) 



The only specimens which I have seen are Mr. Laing's, which are so immature 

 as to make their identification somewhat doubtful.
