形態特徵

• Perennial herb 0.43-0.55 m tall, erect, creeping, branching and rooting at base, branching strictly above; stems solitary or few, compressed and 4-lined when young, soon terete.
• Leaves subsessile or petioles to 2 mm long; lamina 2-4.6 cm long, 0.6-1.3 cm broad, narrowly elliptic, apex obtuse to rounded, base angustate, chartaceous, paler beneath, with 5-6 main lateral veins (uniting to from an intramarginal vein), conspicuous ± lax reticulate venation and numerous pale laminar glandular dots, varying in size.
• Inflorescence terminal, 1-3-flowered, with 6-11 1-3-flowered cymes, shortly pedunculate (1-6 mm long) or subsessile; flowers 5-6 mm in diam., cyathiform, in bud ovoid, acute; sepals 3.5-5 mm long, 1.5-2 mm broad, oblong to lanceolate, obtuse to rounded, entire, with pale glandular lines, erect; petals white, 4-6 mm long, 2-3 mm broad, oblong with sparse laminar pale glandular dots; stamen fascicles orange (?), scale-like, 1-1.5 mm long; ovary ca. 3 mm long, ovoid to ellipsoid, styles 1 mm long, appressed, spreading near apex.
• Capsule 6-8 mm long, 3-4 mm broad, ovoid; seeds ca. 1 mm long, dark reddish brown, densely reticulate, shallowly carinate.
• The above record, the only one as yet from Taiwan, was only the third for the species as a whole. The Taiwan material matches the type specimen from Silhet (Khasya) well. Since the publication of the first edition, <i>T. breviflorum</i> has been recorded from several southern provinces of China, from Yunnan to Jiangsu and Zhejiang. The Japanese species (<i>T. japonicum</i> (Blume) Makino) differs from <i>T. breviflorum</i> in several characters, e. g., leaf-shape, inflorescence form and petal color (pinkish).
