what bell-shaped, consisting of 12-16 unequal scales, surrounded by 

 several short subulate-semilanceolar bracts ; flowers 60-70, not 

 exserted; corolla of bisexual flowers but little wider towards the 

 summit ; anthers enclosed ; ligules of the female flowers minute, 

 slightly shorter than their tube, considerably stretching beyond the 

 stigmata; achenia slender, not half as long as the involucre, grey 

 from a thin appressed when moistened mucous indument, of about 

 half the length of the very tender pappus; the latter hardly emerging 

 beyond the involucre. 



Chatham-Island on sandy places at the sea-beach. 



The collection contains flowering branches ; it remains therefore 

 to be ascertained whether the plant is annual, herbaceous-perennial 

 or frutescent. Branches rather stout, not woody, glabrescent. Upper 

 leaves flat, herbaceous, in circumference approaching to ovate- or 

 lanceolate-oblong, from the middle downward generally slightly 

 dUated ; the upper portion of the leaves always acutely toothed and 

 not unfrequently deeply cut into lobes. Inflorescence terminal, 

 consisting of very many capitula. Peduncles 1" or less long ; most 

 of the special peduncles longer than the flower-heads ; all bearing 

 several subulate- or lanceolate-linear bracts. Involucre 3-4'" long; 

 its scales linear and lanceolate-linear, glabrous except at the tip, 

 forming almost two rows, the narrower outer ones generally over- 

 lapping the searious margins of the inner scales. Basal bracts of the 

 involucre but simply sphacelate at the apex. Bisexual coroUse about 

 2'" long. Radial flowers 10-14; their ligules hardly longer than 

 V", oblong-lanceolate, generally toothless, soon rolled back. Achenia 

 scarcely above 1'" long, only about \"' thick ; their indument ex- 

 panding into a transparent mucus when exposed to warm water. 



This species seems to find amongst New Zealand plants its nearest 

 allied in S. latifolius and S. Banksii. The former of these recedes, 

 according to Dr. Hooker's notes, in larger leaves, a glandular indu- 

 ment of the achenia amd long-emergent pappus. S. Banksii differs 

 (Fl. Nov. Zeal. i. 145) in smaller capitula and achenia almost as long 

 as the involucre. 



Should S. radiolatus prove annual it might be drawn into the 

 series of S. vulgaris. The latter, which has immigrated into several 

 parts of Australia, is principally distinguished by its less robust 

 branches, smaller leaves, which are toothed in their whole length 

 and cut into shorter and blunter lobes, less numerous capitula with 

 fewer flowers, narrower scales of the involucre, the comparative 

 smoothness of the receptacle, which is not raised into toothed
