still the principal European occupant, and in which this remarkable 

 species forms such a prominent feature of the primeval vegetation. 

 Mr. Hunt is moreover highly entitled to this mark of respect for the 

 kind assistance which he afforded to the young traveller in his exer- 

 tions of rendering known the vegetable products of these islands. A 

 hope is simultaneously expressed, that as a permanent resident there 

 the hospitable settler of Pitt-Island may also hereafter advance our 

 cognizance of the vegetation around him. 



In its arborescent growth Senecio Huntii has probably amongst 

 the many hundreds of its congeners in the Victorian and Tasmanian 

 Senecio Bedfordii (Bedfordia salicina, Cand. Prodr. vi. 441) and in 

 the New Zealand S. Forsteri (J. Hook. Fl. Nov. Zeel. i. 148, t. xL) 

 its only rivals. In deep humid forest-gullies, favorable for its luxu- 

 riant development, S. Bedfordii equals S. Huntii in height, and thus 

 both excel as the tallest all others of a cosmopolitan genus, which is 

 recognized next- to Solanum as the richest of all in- species. 



In the systematic series S. Huntii may perhaps find its place 

 nearest to the exclusively Tasmanian S. Brownii (Centropappus 

 Brimonis, J. Hook, in Lond. Journ. of Bot. vi. 124 ; Flor. Tasman. i. 

 225, tab. Ixv.), which although much smaller exceeds also most other 

 species in size. Both plants have many characters in common, but 

 the Tasmanian plant differs in its smoothness, narrower flat leaves, 

 smaller panicles with less large capitula and often shorter peduncles, 

 much less numerous flowers of the heads, fewer and shorter scales 

 and broader and shorter bracts of the involucre as also more grossly 

 serrated upwards thickened bristles of the pappus. 



S. Huntii approaches likewise in many characters to S. glasti- 

 folius (J. Hook. Fl. Nov. Zeel. i. 147, tab. xxxix.), which recedes 

 again in its smoothness, in petioled often toothed leaves, in a less 

 compact inflorescence with fewer and larger capitula, in larger 

 bracts and also in upwards somewhat thickened pappus-bristles. 



The transit of Bedfordia and Centropappus to Senecio, indicated 

 by Dr. J. Hooker, is rendered sufiiciently clear by the discovery of 

 this Chathamian species. 



Senecio radiolatus. 



Upper leaves above the middle toothed and often also pinnatifid, 

 below the middle entire, with cordate or auriculate base sessile, 

 beneath somewhat arachnoid-downy ; their lobes almost semilanceo- 

 late; flower-heads numerous, corymbose-paniculate; receptacle pitted 

 with toothed alveoles ; involucres from cylindrical gradually some-
