 all sides of the stem beneath it.

By the margin of the larger pond at Pondleigh near Hurstpierpoint. 

 "With the usual form of this species there sometimes occur stems 

 which are hardly to be distinguished from W. rostellata.

On clayey soil by a roadside near Hurstpierpoint, and in a stubble 

 at Little-ease. 



Very similar to TV. microstoma, but more slender, with longer 

 stems and shorter and broader squarrose leaves ; its fruit too is 

 ripened in November, whereas that of W. microstoma is scarcely 

 mature before March or April.

On the cliffs at Gin Gap near Newhaven. 



Plants growing together in small patches amongst the short starved 

 herbage on the edge of the cliff, exposed to the full influences of the 

 sea breezes. The stems are from one to three-fourths of an inch high, 

 fastigiately branched ; the leaves are green or yellowish green in the 

 upper parts, below ferruginous ; the capsules are pale yellowish 

 brown, erect or gibbous, the mouth red and the setae yellow. It is 

 readily known from W. mucronata, to which it is nearest allied, by 

 its much greater size, thicker leaves, and coloured mouth of its cap- 

 sules, which are ripened in March.
