備註: GBIF: Chorisia speciosa is syn of Ceiba speciosa #The Plant List 學名 美人樹是木棉科的植物,花朵豔粉紅色,花瓣狹長,中央有明顯的花蕊 樹身的刺較木棉銳利,開花是全株豔粉紅色,同時樹葉疏落,但枝幹帶綠色,遠看非常搶眼. information from hkwildlife.net 花: 十一月攝; 果: 二月攝 絲木棉的嫩枝條的確是綠色的, 老身了的幹莖便會呈現木質化(lignified)的顏色。木棉科通常都是有中央主幹(central leader)的喬木.絲木棉在HK的花期通常由9-12月.嫩枝才有刺.樹老了也不再須要用刺去保護樹幹 thanks Edmond Wong's information The Plant List: Ceiba speciosa (A.St.-Hil.) Ravenna is an accepted name This name is the accepted name of a species in the genus Ceiba (family Malvaceae錦葵科) Synonym: Chorisia speciosa A.St.-Hil. 深圳植物誌: 落葉小喬木,高8-15m;樹乾基部常擴大,幼時有圓錐狀的短皮刺,幼樹樹皮常綠色,含葉綠素,在落葉階段可進行光合作用,老後逐漸變為灰色。掌狀複葉;葉柄長4-12cm,無毛;小葉6-7枚,堅紙質,窄長圓形至長圓狀倒披針形,中央1枚較大,長5.5-12cm,寬2.5- 5cm,基部楔形,邊緣基部以上有鋸齒,先端漸尖或微鈍,上面亮綠色,下面淡綠色,兩面無毛。 花單生或2-3朵簇生在枝頂葉腋,有時排成頂生的聚傘圓錐花序;花萼杯狀,長2-2.5cm,裂片4-6,長為萼筒的1/2,頂端鈍或近圓形;花瓣5片,外卷,匙狀倒卵形,長9.5-10.5cm,淡紫或粉紅色,稀白色,中部以下常色淺或近白色並帶紫斑;外輪雄蕊管長約1.8 cm,有不育花藥10枚,淡紫紅色,具皺紋狀的毛,內輪雄蕊管長約8.5cm,具能育花藥5枚;花柱稍長過內輪雄蕊管,柱頭頭狀,被短柔毛。蒴果卵球形。種子多數,藏於綿毛中。花期:夏秋季。花期:夏秋季。 FOHK: Deciduous trees, 8–15 m tall, trunk with short spines. Leaves spirally arranged on the current years’ branches; petioles 4 –12 cm, petiolules 6–15 mm, glabrous; leaflets 6–7, firmly papery, narrowly oblong to oblong-oblanceolate, the center one larger, 5.5–12 × 1.5–2.5 cm, base cuneate, apex ± acuminate, margin serrate above the base, glabrous, adaxially bright green, abaxially pale green. Flowers solitary or 2–3 clustered in axils of apical leaves, sometimes appearing a cymose-panicle due to the subtending leaves falling off. Pedicels 1.5 –2.5 cm. Caylx cup-shaped, 2–2.5 cm, apex shallowly 4–6-lobed; lobes unequal, apex obtuse or sub-rounded. Petals 5, distinct, oblanceolate, 9.5 –10.5 cm, broadest at middle (ca. 3.5 cm), dark red, pink, white with dark strips on the proximal half of adaxial surface. Outer stamen-tube ca. 1.8 cm; anthers 10, sterile, dark purplish red, covered with crisped hairs; inner stamen-tube 8.5 cm, with 5 fertile anthers. Style slightly longer than inner stamen-tube; stigma capitate, hairy. | |
