Characteristics

Herbs perennial, 6.5-21 cm tall. Stem sparsely brown crisped villous. Basal leaves with petiole 1.2-2.2 cm, margin brown crisped villous; leaf blade elliptic, lanceolate, or oblong to linear-oblong, 1.1-2.2 cm × 3-10 mm, both surfaces glabrous, margin brown pilose or glabrous. Cauline leaves lanceolate to oblong, 0.4-2.2 cm × 1-6 mm, both surfaces glabrous, margin brown crisped villous; proximal ones larger with petiole longer, distal ones smaller with petiole gradually shorter to absent. Flower solitary or cyme 2-3.7 cm and 2-4-flowered; pedicels 0.9-1.3 cm, brown crisped villous. Sepals erect, then spreading to reflexed, elliptic, or ovate to narrowly so, 3-6.1 × 1.5-3.5 mm, abaxially and marginally brown crisped villous or glabrous on both surfaces, veins 3-11(-13), not confluent at apex, apex obtuse or acute. Petals yellow, elliptic or obovate to narrowly ovate, 7.9-10.3 × 2.9-6.8 mm, 2-callose, 7-11(-17)-veined, base with a claw 0.3-0.5 mm, apex subobtuse or acute. Stamens 4-5.5 mm. Ovary subsuperior, ovoid, 2-5 mm; styles 1-1.8 mm. Fl. and fr. Jun-Sep. 2n = 16, 32.
More
Plants loosely tufted, not stoloniferous or sometimes shortly so, rhizomatous, caudex present or not. Leaves basal and cauline, (distal clasping); petiole absent on distal leaves, otherwise ± flattened, 3-20(-35) mm; blade linear or linear-oblanceolate to spatulate, unlobed, (5-)10-30 mm, thin to slightly fleshy, margins entire, eciliate or sparsely reddish brown-ciliate, (with apical nonsecreting hydathode), apex acuminate or acute, surfaces glabrous or sparsely reddish brown-villous. Inflorescences 2(-4)-flowered cymes, sometimes solitary flowers, (flowers initially nodding), 4-30(-35) cm, sparsely to ± densely reddish brown-villous; bracts sessile. Flowers: sepals ascending to spreading, reflexed in fruit, (sometimes purplish), triangular, margins reddish brown-ciliate, surfaces glabrous (rarely reddish brown-hairy); petals yellow, often drying cream, often proximally orange-spotted, elliptic to oblong or obovate, 6-18 mm, 2+ times longer than sepals; ovary superior. 2n = 16, 24, 32.
