Flora of North America species comparison

simple or several from base, decumbent or erect, (unbranched), to 2 dm.

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

(petiole sharply differentiated from blade, slender);

blade suborbicular or obovate to rhombic, 4–8 cm, (base abruptly narrowed to petiole), margins entire, sinuate, or shallowly dentate, (abaxial surface densely pubescent, adaxial lightly pubescent).

(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).

(proximal petiolate, distal sessile);

blade obovate to rhombic, 0.8–2.3 cm, margins entire or shallowly toothed.

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

dense, (somewhat elongated in fruit).

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

sepals elliptic or oblong, ca. 6 mm, (lateral pair not saccate or subsaccate, cucullate, median pair thickened apically, cucullate);

petals spatulate, ca. 9 mm, (claw expanded at base).

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).

(horizontal to ascending, sigmoid or slightly curved), 8–11 mm, (stout).

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

(sessile or substipitate, often becoming copper-red in age), subglobose or ellipsoid, inflated, 6–9 mm, (firm, glossy);

valves (not retaining seeds after dehiscence), glabrous throughout;

replum as wide as or wider than fruit;

ovules 4–8(–12) per ovary;

style 3.5–7 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.

somewhat flattened.

slightly flattened.
