simple from base, prostrate to decumbent, (unbranched, from within and below leaf clusters, slender), 0.2–0.8 dm.

(petiole slender, often narrowly winged);

blade obovate to orbicular or rhombic-orbicular, 2–9 cm, (base abruptly narrowed to petiole), margins usually entire, rarely with few scattered teeth, (apex rounded or obtuse, sometimes with apical mucro).

(tufted, erect or ascending, silvery);

blade linear to oblanceolate or (outer) oblanceolate to obovate or rhombic, 1.5–3.3 cm, (base sometimes subhastate), margins entire or dentate, (often involute).

blade spatulate to oblanceolate, 1–3 cm, margins entire, (apex usually obtuse).

blade nearly linear, to 1.5 cm, margins entire.

loose, (elongated in fruit).

dense, (subcorymbose).

ovules (2 or) 4 per ovary;

style 4–6(–9) mm.

(usually pendent), obdeltate, compressed (angustiseptate), 2–4 mm, (wider than long, base tapered to acute angle, apex truncate with inflated shoulders);
