| 備註: GBIF: Trigonostemon chinensis is syn of Trigonostemon viridissimus 高 2–4 m；嫩枝密被黃褐色短毛，近無毛；葉柄 1–2 cm，被硬毛至近無毛，先端具 2 圓錐形腺體；葉薄紙質，倒卵狀橢圓形至長圓形，8–18 × 3–5.5 cm，基部楔形至圓形，先端急尖，通常有尾尖，嫩時兩面有毛，老時無毛或近無毛，葉面通常密佈瘤狀，全緣或上半有不明顯鋸齒；側脈 6–8 對；總狀花序頂生，9–18 cm，多毛或有硬毛至近無毛；雄花︰小花梗纖弱，2–5 mm；萼片 5，長圓形，約 1.2 mm，多毛；花瓣倒卵形，5–6.5 mm，黃色；花盤環形；雄蕊 3；雌花︰小花梗棍狀，1–1.5 cm；萼片 5，披針形，不等，5–6 mm，背面被毛；花瓣倒卵形，12 mm，黃色；子房無毛；柱頭 3，短；蒴果扁球形，直徑約 1.2 cm，無毛，有 3 縱溝 觀察所得香港花期為 4–5 月。《香港植物誌》指出本種極稀有，僅間斷分佈於香港、中國廣西及海南。本種外形極為普通，若非花期實在難以輕易辨認；在云云鬆散大石間仔細找尋實非易事，拍攝花朵之際，腳下一塊如冰箱大小的石頭毫無先兆下脫落，跌入深谷，所幸並非重心所在。種名 chinensis 解作「中國的」。source from: 香港野地生態摘記-剎那 FOHK Shrub, 2–4 m tall; young branches densely tawny pubescent, glabrescent.
