few from base, erect with outer usually decumbent, 1–3.5(–5) dm.

several from base, decumbent to prostrate, (well-exserted beyond basal leaves), 0.2–0.5 dm.

(erect);

blade narrowly lanceolate to linear or (outer) oblanceolate, (1–)2–6(–9) cm, margins usually entire, rarely shallowly dentate, (inner involute, outer usually flat, base usually with some simple trichomes).

(petiole differentiated from blade);

blade (slightly cupped, leathery, nearly 1 mm thick), oblanceolate to orbicular, 1.2–2 cm, margins entire, (apex acute).

blade narrowly oblanceolate to linear, (1–)2–4(–8) cm, margins flat or involute.

blade spatulate, similar to basal.

compact, (elongated and loose in fruit, densely-flowered).

dense, (subumbellate).

sepals oblong to broadly elliptic, 4–7(–8) mm, (lateral pair subsaccate, median pair cucullate);

petals oblanceolate or obovate, (5–)6.5–9.5(–11) mm, (claw undifferentiated from blade, or blade gradually narrowed to claw).

sepals (pale yellow), elliptic to oblong, 3.5–4.0 mm, (median pair somewhat thickened apically, cucullate);

petals lingulate, 5–6 mm.

(usually recurved), (5–)10–20(–25) mm.

(ascending, curved), 5–7 mm.

subglobose or obovoid, usually inflated, sometimes slightly compressed, (3–)4–6 mm;

valves densely pubescent, trichomes spreading, usually pubescent inside, trichomes appressed, sessile;

ovules (4–)8–12(–16) per ovary;

style 3–4.5(–6.5) mm.

globose or ellipsoid, slightly inflated (with slight apical constriction), 3–6 mm;

valves pubescent, trichomes closely appressed;

ovules 8 per ovary;

style 1–3 mm (shorter than mature fruit).

slightly flattened.

plump, (oblong).
