|---|---|---|---|
| Habit | Perennial herbs with stoloniferous roots | Perennial herbs, stolons poorly developed | Biennial-perennial with stoloniferous roots |
| Leaves | Basal leaves rosulate, crowded towards base, cauline leaves mostly obovate, elliptic to spathulate; apex rounded to sub-rounded | Basal leaves crowded, cauline leaves spathulate to obovate-oblong, apex obtuse to rounded | Basal leaves indistinctly rosulate, cauline leaves obovate, spathulate, apex obtuse |
| Calyx | 10–12 mm long, lobes 2–3.5 mm long, unequal, lanceolate, slightly triangular with acute apex, sinus between lobes obtuse to sub-rounded | 5–7 mm long, lobes 2–3 mm long, sub-equal, narrowly triangular with apex acute, sinus between lobes acute | 8–17 mm long, lobes 3–6 mm long, unequal, narrowly oblong, linear to lanceolate with obtuse-acute apex, sinuses between lobes obtuse |
| Corolla | Ovate-obovate with acute apex, margins scabrous, crenulate | Elliptic-ovate with apex obtuse, margins entire | Obovate, ovate-oblong with obtuse apex, margins entire |
| Plicae | Horizontally truncate, margins dentate to erose | Triangular, margins entire | Triangular to truncate, margins entire or 2 to 3 dentate |
| Stamens | Inserted from the middle of the tube | Inserted at basal part of corolla tube | Inserted at middle of corolla tube |
| Carpels | 5–6 mm long, ovary narrowly ovate to elliptic, style 2–2.5 mm long, stigma lobes orbicular to coiled | 10–12 mm long, ovary ellipsoid, style 0.5–1.5 mm long, stigma lobes semi-orbicular | 5.0–13 mm long, ovary narrowly lanceolate, style 1.5–3 mm long, stigma lobes coiled |
| Seeds | 0.3–0.4 mm, sub-orbicular, ovate, elliptic, oblong seed coat alveolate, shallow and hexagonal pits | 1–1.2 mm, ellipsoid to sub-globose, seed coat with spongy and complex hexagonal pit | 0.6–0.8 mm, ellipsoid, glistering, seed coat with rough and complex hexagonal pits |
