備註: 水團花VS風箱樹: 重點在托葉形狀跟花、萼裂片間的腺體有冇。 水團花VS海南槽裂木: 重點在托葉形狀 基於分子種系發生學研究結果,烏檀族下的水團花屬現時包含了幾個過往曾經獨立的屬,當中包括槽裂木屬。所以兜兜轉轉,又返咗歸水團花屬。 (thanks Crawford's info) 與水團花有些似,葉整體大些,花黃色,喬木。(thanks Daniel's info) 中國植物誌: 喬木或灌木,高達30米;幼枝栗色,無毛或近無毛。葉厚紙質,橢圓形至橢圓狀長圓形,長4-10厘米,寬2-3厘米,頂端漸尖,基部楔形,兩面無毛或被短柔毛;側脈7-10對,下面無毛,脈腋窩陷內無毛或有稀疏的毛,網脈不明顯;葉柄長3-10毫米,無毛或被短柔毛;托葉線狀長圓形至鑽形,全緣,稀頂端有凹缺,無毛。頭狀花序不計花冠直徑6-8毫米,花序梗單一,不分枝,或有時二歧狀分枝;小苞片線狀棒形至線狀匙形,頂端具緣毛;花萼管長0.5- 0.7毫米,無毛或有稀疏的毛,基部通常有長毛,萼裂片線狀長圓形,長1.5-2毫米,內外均有稀疏的毛;花冠黃色,芳香,高腳碟狀,花冠管的內外均無毛,花冠裂片三角形;花柱伸出,柱頭倒卵圓形。果序直徑4-6毫米;小蒴果長1.5-2.5毫米,被稀疏的短柔毛。花期6-7月。 FoHK: Trees or shrubs, up to 30 m tall; branchlets glabrous or nearly so. Leaves opposite; stipules linear‑oblong to subulate, 4–6 × 2 mm, glabrous; petioles 3–10(–25) mm, glabrous or pubescent; leaf blade thick‑papery, elliptic to elliptic‑oblong, 4 – 10 × 2 – 3.5 cm, base cuneate, apex acuminate, glabrous or pubescent on both surfaces, with domatia in axils of lateral veins; lateral veins 7–10 on each side of midvein; reticulation of veins inconspicuous. Flowering heads axillary, ca. 15 mm in diam. across corollas; peduncle unbranched or sometimes branched like a simple dichasium. Interfloral bracteoles filiform‑clavate to filiform‑spathulate, 0.5–1 mm, ciliate at apex. Hypanthium 0.5–0.7 mm, glabrous to sparsely hairy. Calyx‑tube 1.5–2 mm, sparsely hairy; lobes linear‑oblong, 1.2–1.6 mm. Corolla hypocrateriform, 3–3.5 mm, glabrous; lobes deltoid, 0.7–1 mm. Style 7–8 mm, exserted. Fruiting heads 4– 6 mm in diam. | |
