E-ootstock perennial, with numerous rather slender slightly 

 woody divisions, producing ascending simple barren shoots and 

 erect unbranched flowering stems. Leaves of the barren shoots 

 straiishapcd-linear, rather obtuse, those of the flowering stems 

 oblanceolate-linear, and blunt near the base of the stem, but linear- 

 acute in its upper portion ; all 3-nerved and with scabrous margins. 

 Plowers solitary, usually only 1 on the stem. Calyx glabrous, very 

 indistinctly ribbed, with 4 involucral bracts, which are roundish 

 obovate, abruptly acuminated into a very short acute point, which 

 reaches about one-fourth the distance to the apex of the broadly 

 triangular rather blunt calyx teeth. Petals with the laminoo in- 

 versely deltoid, rather truncate and tootlied at the apex, nearly 

 contiguous. 



On rocks. Very rare. On the abrupt limestone precipices of 

 Cheddar Rocks, Somersetshire. 



Encland. Perennial. Late Summer. 



Csespitose. Rootstock with long slender divisions, producing short 

 barren tufts with narrow leaves 1^ to 2 inches long ; flowering stems 

 with the leaves shorter. The upper leaves have the lateral nerves 

 at the margin, the lower ones a little way from it. Involucral 

 bracts membranous, with the point hei'baceous. Plowers generally 

 only 1 on each stem, more rarely 2, f inch long, 1 inch across, 

 with the calyx tinged with purplish red, cylindrical, thick in pro- 

 portion to its length. "Flowers delightfully fragrant, of a delicate 

 pale rose-colour" (Smith). Petals with the lamina? irregularly 

 toothed at the apex, the teeth not extending beyond one-sixth or 

 one-eighth the length of the laminse, more or less hairy at the 

 base. Plant growing in tufts, glaucous and glabrous, Avith the 

 leaves rough at the margins.
