形態特徵

• Perennial herbs, 10–25 cm tall; stems erect, often tufted, pubescent.
• Leaves chartaceous, petiolate; petioles pubescent, 0.5–1.5 cm long; blades ovate to rhombic-ovate, 1.5–3.0 cm long, 1.0–2.0 cm wide, base obtuse or truncate, apex acuminate to obtuse, margins crenate 2–4, glabrous, lower surface purple, 3 or 4-nerved.
• Flowers 4–10, opposite, forming a loose terminal raceme, 2–4 cm long, bracts foliaceous, ovate, small, entire, ciliate; corolla white with a purplish spot in throat, 1–1.5 cm long, pubescent. Pollen grains 3-colpate, subprolate, isopolar, 23–30×16–20 μm, tectum irregularly rugulate with microperforae.
• Nutlets orbicular, 1.4×1.2 mm; coat with mammillate tubercles.
• Chromosome number 2n = 26. <li>The specimen identified by A. Henry (<i>Henry 2073</i>, K) as S. indica L. (as listed in his List of Plants of Formos. 802.), is correctly referred to<i> S. taiwanensis</i>. The type specimen of <i>S. taiwanensis </i>C. Y. Wu collected by <i>Kudo et Mori s. n. </i> Apr. 1930 from Arayuwan, is from the southern part of Taiwan, but the precise locality is unknown. The attribution of this species to Mt. Ali by Li (1977) is incorrect.</li>
