Stems with rather elongate straggling branches, which, as well 

 as the main stem, are more or less puberulent, with the pubescence 

 intermixed with gland-tipped hairs. Leaves regularly whorled, 

 4 in a whorl, very sliortly stalked, oblong-ovate, oblong or strap- 

 shaped, with strongly revolute margins, pubescent or sub-glabrous 

 above, glaucous with white stellate scales beneath except on the 

 midrib, ciliated with rather long or long gland-tipped hairs, usually 

 without fascicles of leaves in the axils. Elowers slightly drooping, 

 sliortly stalked, in terminal slightly secund head-like umbels, which 

 have sometimes a whorl of flowers beneath them. Pedicels a little 

 longer than the calyx, with a leaflike bracteole about the middle, 

 but no bract at the base, except in those of the whorl beneath the 

 umbel when it is present. Calyx-segments herbaceous, lanceolate 

 or oblong - lanceolate, ciliated with gland - tipped hairs. Corolla 

 three or four times as long as the calyx, oval-urceolate, scarcely 

 curved, with 4 very short broadly-ovate teeth at the apex. Anthers 

 included, each with 2 awns or spurs at the base. Style exserted. 

 Ovary glabrous or downy.

Stem sub-paniculately branched, the flowering-branches not all 

 attaining the same height. Leaves with the margins usually so 

 much rolled back as to be oblong or oblong-strapshaped, the upper 

 side and midrib beneath generally pubescent. Branches, pedicels, 

 and calyx-segments and capsule more or less pubescent or woolly- 

 pubescent.

 Cornwall, the Isle of Wight, and Kent, to Orkney and Shetland.
