are certainly thickened, and were perhaps green in that part simi- 

 larly to those of A. maritima. The calyx-tube is not so thickly 

 hairy as in the preceding plant, but is similarly covered through- 

 out with hairs ; it is about as long as the limb, which has very 

 short acute lobes terminating in longer awns than those of A. 

 maritima. 



Boissier places our plant (which he has seen from the island 

 of StafFa alone) as the variety scotica of his A. pubigera, with 

 which species, if I am correct in supposing that my specimens 

 are the same plant, it does not very well accord. A. pubigera 

 appears to be only known in cultivation and is stated to be " tota 

 dense pubescens," and its involucral bracts are described as 

 "omnino scariosis.^^ In our plant the pubescence is far from 

 being dense, on the leaves it is very thin and scattered, and the 

 involucre is quite glabrous. The latter part also cannot be de- 

 scribed as " omnino scariosum,^^ for its bracts are certainly much 

 thickened on the back, and present the appearance of having 

 been green there. 



My specimens vary greatly in size, but are doubtless states of 

 one species. They were obtained at Southampton in June 1827, 

 Tintagel, Cornwall, July 1839, by myself; at West Wittering, 

 Sussex, in Nov. 1843, by the Rev. W. W. Newbould; Folke- 

 stone, Kent, by Mr. W. Pamplin ; and Tenby, Pembrokeshire, 

 by Mr. F. J. A. Hort. 



The plant gathered near Reikiavic in Iceland in July 1846 is 

 undoubtedly of this species.

Leaves short, usually much shorter than the scape, bluntly 

 pointed or sometimes even on the same plant acute. The outer 

 involucral bracts are different in shape from the others, but do 

 not exceed them in length. The tube of the calyx is perfectly 

 glabrous between the prominent hairy ribs ; it is about as long 

 as the limb, and has very broad short and acute lobes with the
