Flowering stems up to 10 cm. long, erect, shortly and subpatently papillose-hairy, leafy from the base to the inflorescence, the leaves ± dense, decussate, the undermost similar to those of rosettes and longer than the internodes, the others successively smaller and relatively narrower, longer than or subequalling the internodes, appressed or subreflexed, papillose on the outside towards the base.
Calyx 2·25-2·6 mm.; sepals 1·5-2 mm. long, triangular-lanceolate, attenuate towards the acute apex, carinate, equalling or longer than the half of the corolla, glabrous, shortly and irregularly ciliate at the margin and sometimes along the median line, rarely without cilia.
Old branches woody, covered by the persistent, dense, dried leaves of previous years; young branches up to 5 cm. long, ending in leaf-rosettes up to 2 cm. in diam., either barren or surrounding a flowering axis.
Flowers 5-merous, in dense, terminal corymbs, 1·5-3 cm. in diameter; inflorescence-branches papillose-pilose; pedicels up to 4 mm. long, sparsely papillose to glabrous.
Corolla c. 3·5 mm. long, white; petals 1·5-1·75 mm. broad, obovate-elliptic, obtuse, not or indistinctly mucronate, smooth.
Scales c. 0·5 x 0·5 mm., subrectangular-cuneate, rounded-truncate at the apex.
Filaments c. 1·5 mm.; anthers c. 0·4 mm., subcircular.
Follicles 2·25-2·5 mm. long (with the styles).
A low, much branched undershrub.
