rhizomatous, procumbent or creeping, much-branched, bearing terminal rosettes.

decumbent, lateral branches from proximal axils, rosettes formed in proximal axils (giving rise to flowering shoots).

erect, simple, 3–14 cm;

leaf blades spatulate-oblong or elliptic-oblong, base not spurred;

offsets not formed.

ascending, appearing angled when dry, simple or branched, 4.7–6 cm;

leaf blades elliptic-oblong or oblanceolate, base not spurred;

offsets axillary rosettes only basally.

alternate, spreading, petiolate;

blade green, often glaucous or pruinose, spatulate, terete to laminar, 7–19 × 4.5–10 mm, base not spurred, not scarious, apex rounded or truncate, submucronate, (surfaces papillose marginally).
