| 備註: Justicia championii 杉氏爵床 ／ 圓苞杜根藤 同杜根藤 Justicia quadrifaria 現時還是兩個不同品種。其實兩者真係好相似，外觀上就葉形有些少不同。 兩者分別參加文獻 thanks Crawford's info Flowering Period: Oct-Nov Photo taken on 2014.9.14 hkisland FOC: Herbs to 50 cm tall. Stems 4-angled, sulcate, retrorsely pubescent. Petiole (0-)0.5-1.5 cm, sulcate, pubescent; leaf blade elliptic, oblong-elliptic, ovate, or lanceolate, 1-7(-10.5) × 0.5-2(-3.5) cm, sparsely pubescent when young, soon glabrescent or abaxially pilose along midvein, cystoliths adaxially numerous, secondary veins 3-6 on each side of midvein, base cuneate to attenuate, margin entire, apex acute to obtuse. Spikes axillary, usually 3-flowered, several clustered; peduncle 2-4 mm, sparsely pubescent; bracts petiolate, subleaflike, circular to obovate-spatulate or sometimes elliptic, 5-11 × 2-6 mm, glabrous or adaxially sparsely pilose, veins 1-3 on each side of midvein, apex rounded to obtuse; bracteoles subulate to triangular, ca. 1 mm, glabrous or sparsely yellow puberulent, apex acute. Calyx 5-lobed almost to base; lobes yellowish white except for green along veins, linear-lanceolate, 6-7 mm, 1- or 2-veined, margin ciliate. Corolla white with 2 purplish red streaks, 7-10 mm, outside puberulent; lower lip ovate, ca. 4 × 3 mm, 3-lobed, middle lobe semicircular and ca. 0.8 × 1.3 mm, lateral lobes ovate and ca. 1.2 × 1 mm; upper lip lanceolate, ca. 3.5 × 1.5 mm, apex emarginate. Stamens exserted; filaments ca. 4 mm, glabrous; anther thecae superposed, lower one spurred at base, upper one muticous. Ovary glabrous; style ca. 6 mm, sparsely pubescent toward base; stigma capitate. Capsule 8-9 mm, glabrous, 4-seeded. Seeds oblong, ca. 2 × 1.5 mm, verrucose. Fl. and fr. Aug-Oct. Inflorescences of Justicia championii appear to be axillary clusters of flowers but are much-reduced spikes or racemes with a very short rachis. | |
