形態特徵
- Rhizome with branching scars and scale leaves, sending out stolons which develop new plantlets. Fertile branches many, petiole-like, highly variable in length.
- Petiole variable, 0.5-5 cm long. Leaves blade ovate-orbicular, rounded, 2-8 cm across, deeply cordate at base, abaxially densely glandular dotted.
- Flowers ca. 1.0-1.2 cm in diameter, 6-10 clustered at nodes, 4-5-merous. Pedicels 3-5 cm long. Calyx deeply 4-5-lobed 10 near base; lobes ea. 3 mm long, ovate-lanceolate, apex obtuse, margins hyaline. Corolla white with a yellow throat; lobes 4-5, oblong-lanceolate, up to 5.5 mm long, apex 2-lobed, margin with fimbriate hairs. Stamens as many as corolla lobes, inserted in the throat of the corolla, each with a small tufts of glandular hairs or not. Pistil bottle-shaped; style 2-lobcd; hypogynous disc glands as many as stamens, orbicular, cililolate at tips with papillose hairs.
- Capsule globose, ca. 3 mm long. Seed ellipsoid, ca. 1 mm long, with sparse tubercles rounded at the distal ends.
- Chromosome number 2n = 4x = 36. <li>This species is distributed both in Taiwan and Lanyu island and has geographical differentiation. The population in Taiwan has bigger leaves (up to 8 cm across), petal with a small tufts of glandular hairs at base and few turbaculae on seed margin, but the population in Lanyu island has smaller leaves (2-5 cm across), petal without a small tufts of glandular hairs at base and more tuberculae on seed margin. The chromosome number of Taiwanese plant is 211 = 36, but 211 = 56 in Japanese plant (Shigenobu & Tanaka, 1980). So, a further study is needed for this taxon. </li>
