備註: 麻楝d小葉葉寬較大, 小葉間的間距也較人面子的緊密 from hkwildlife.net thanks crawford's info: 麻楝是花單性,雌雄同株的物種。 一談到楝科花性別問題就是件很麻煩的事。它們的花很細,如果有分雌雄花的話,通常都是看起來差不多。加上部分個别物種又會有些相當特別的機制。 深圳植物誌: 喬木,高10-25m。 老枝的皮片狀脫落,幼枝紅褐色,密被短柔毛或無毛。 葉為偶數羽狀複葉,長20-50cm,有小葉10-16枚;葉柄長4-10cm,與葉軸及小葉柄均密被短柔毛;小葉柄長4-8mm;小葉互生;小 葉片紙質,卵形、卵狀披針形或長橢圓形,長5-12cm,寬2.5-5cm,基部圓,甚偏斜,邊緣全緣,先端漸尖至尾狀漸尖,兩面均疏 被短柔毛或均無毛,有時下面被短柔毛,上面無毛,側脈每邊10-15條,在下面每條側脈的脈腋內有一簇長硬毛。 聚繖圓錐花序較疏散,長及複葉的1/2;花序梗及分枝及花梗均疏被短柔毛或近無毛;花梗長4-5mm,有關節;花芳香,長1.4-1.7 cm;花萼小,長約2mm,外面密被短柔毛,萼齒寬三角形,甚短;花瓣黃色或略帶紫色,條狀長橢圓形或近匙形,長1.2-1.5cm,外面近先端 疏被短柔毛;雄蕊管筒形,略短於花瓣,先端有10個淺圓齒,花藥10枚,生於雄蕊管的頂端;子房具短柄,疏被短硬毛,上部漸狹 並延伸成圓柱形的花柱,與雄蕊近等長或略短,柱頭頭狀,上面不明顯3淺裂。 蒴果橢圓體形或近球形,長4-4.5cm,直徑3.5-4cm,成熟時褐色,表面密生淡褐色的小疣狀突起,先端有短尖。 種子橢圓形,長約7mm,寬約5mm,扁平,頂端有寬的膜質翅。 花期:4-8月。 果期:7月至翌年1月。 FoHK: Tree, to 25 m tall.
