| 備註: 中華孩兒草-莖具4棱 孩兒草-莖圓柱狀 中華孩兒草-花序4行的苞片形態差不多； 孩兒草-中間開花那兩行的苞片，跟傍邊兩行的苞片唔同樣。 thanks Crawford's info 中華孩兒草:Spikes terminal or axillary, 1-7 cm, 2-sided; bracts 4-ranked, all fertile (4行都係可育花), elliptic, 7-8 × 2-4 mm, margin sparsely ciliate, apex acute 孩兒草:單邊穗狀花序，苞片兩型，分不育苞片 (冇花開) ，跟可育苞片 (有花開). 中間兩行苞片有寬膜又比較圓，會開花. 外邊兩行就比較惰圓，膜又比較窄, 有小尖頭, 不會開花. thanks Crawford's info FoHK Spreading to erect herbs, up to 70 cm tall. Stems slender, quadrangular, sulcate, slightly puberulent, usually rooting at lower nodes. Petioles 0.5–3 cm, pubescent; leaf blades membranous, ovate to oblong‑lanceolate, 2.5–9 × 1.8–3 cm, base cuneate or attenuate, apex acute or obtuse, margin entire or slightly undulate, glabrous except for sparsely hirsute along the veins, lateral veins 5–6 pairs. Spikes terminal or axillary, 1–7 cm, 2‑sided. Bract 4‑ranked, dimorphic, outer sterile ones elliptic, ca. 6 × 2–4 mm, sparsely ciliate, inner fertile bracts obovate, or obovate‑oblong, 6–8 × 2.5–4 mm, apex acute; bracteoles orbicular or ovate, 6–7 × 4–5 mm, apex mucronate, margin membranous, sparsely ciliate. Calyx deeply 5‑lobed; lobes linear‑lanceolate, ca. 5 mm. Corolla bluish, 6 – 8 mm, outside slightly pilose and glandular‑punctate; limb 2‑lipped, the upper lip shallowly dentate, lower lip 3‑lobed, lobes ca. 7 mm. Stamens 2; anthers 2‑thecous, thecae subequal in size, lower theca has basal spur. Ovary 2‑locular; style ca. 1 cm, glabrous, stigma obtuse. Capsule ovoid ca. 6 mm, 4‑seeded. Seeds lenticular, ca. 1.5 mm wide, minutely tuberculate. 中國植物誌: 草本，基部匍匐，高達70厘米。莖纖細，4棱，具溝糟。葉具柄，柄長5-15毫米，葉片卵形，橢圓形至橢圓狀矩圓形，長2.5-9厘米，寬1.8-3厘米，頂端尖至近漸尖，基部寬楔形，側脈每邊5-6條。 穗狀花序較疏鬆，長1-3 (-7)厘米，寬約1.5厘米，頂生或生上部葉腋，具總花梗，長1-2厘米，小穗在花序軸上互生，密集；苞片橢圓形至匙形，長7-8毫米，疏生短柔毛，覆瓦狀排列；小苞片2，橢圓形，長約5毫米，具膜質邊緣和睫毛；花萼裂片5，條狀披針形，長3-4毫米；花冠淡紫藍色，長約1.5厘米，2唇形，上唇三角形，下唇3裂，外面被白色柔毛；雄蕊2，藥室不等高，下方1室具小矩。蒴果長約6毫米，開裂時胎座由蒴底彈起，種子4粒。 FOC: Herbs to 70 cm tall, spreading to erect.
