- 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 “ommnino 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
