ascending or sometimes procumbent, few- to many-branched, not filiform.

ascending or spreading, radiating from axils of basal rosette leaves, sometimes purple tinged, many-branched, slender.

axillary fascicles absent;

basal frequently in primary and secondary rosettes 9–45 mm diam., blade linear, 10–20 mm, not succulent, apex apiculate, rarely aristate, glabrous;

cauline not conspicuously connate basally, rarely forming inflated cup in cespitose, alpine plants, blade linear, sometimes linear-subulate in cespitose plants, 4–20(–25) mm, not fleshy, apex apiculate, glabrous.

axillary fascicles absent;

basal in primary rosettes, secondary rosettes absent, blade subulate to linear, to 20(–30) mm, fleshy, apex apiculate, glabrous;

cauline connate basally into shallow cup, blade often purplish, subulate to linear, 4–16 mm, becoming shorter toward stem apex, scarious, apex apiculate, glabrous.

frequently recurved during capsular development, erect in fruit, filiform, glabrous.

filiform, glabrous.

axillary or terminal, 5-merous, very rarely some 4-merous;

calyx base glabrous;

sepals elliptic, 2–2.5 mm, hyaline margins white, rarely purple in alpine specimens, apex obtuse to rounded, remaining appressed following capsule dehiscence;

petals elliptic, (1–)1.5–2 mm, shorter than or equaling sepals;

stamens (5 or) 10.

calyx base glabrous;

sepals frequently purplish, nearly orbiculate to elliptic, 1.5–2 mm, hyaline margins nearly always purple, sometimes only at apex, apex rounded, glabrous, remaining appressed following capsule dehiscence;

petals narrowly elliptic, 1.5–2 mm, equaling to slightly shorter than sepals;

stamens 8 or 10.
