備註: 深圳植物誌: 小枝、葉柄、葉軸、花序梗和花序軸均有皮刺。長刺楤木 除小枝疏生短小的皮刺外,葉柄、葉軸、花序梗和花序軸均無刺或偶有短小的皮刺,密被黃褐色絨毛。楤木 中國植物誌: 小喬木、灌木或多年生草本,通常有刺,稀無刺。葉大,一至數回羽狀複葉;托葉和葉柄基部合生,先端離生,稀不明顯或無托葉。 花雜性,聚生為繖形花序,稀為頭狀花序,再組成圓錐花序;苞片和小苞片宿存或早落;花梗有關節;萼筒邊緣有5小齒;花瓣弓,在花芽中覆瓦狀排列;雄蕊5,花絲細長;子房5室,稀4-2室;花柱5,稀4-2,離生或基部合生;花盤小,邊緣略隆起。果實球形,有5棱,稀4-2棱。種子白色,側扁,胚乳勻一。 本屬為小喬木、灌木或多年生草本,通常為二至三回羽狀複葉,花5數,花柱離生或基部合生,和五葉參屬Pentapanax Seem. 的關係密切,並較其進化程度高,但花柱的合生程度則不及五葉參屬。 FOC: A thorough revision of Aralia sect. Dimorphanthus was recently published by Wen (Cathaya 15-16: 1-187. 2004), treating material assigned to the first 19 species presented below. Wen adopted circumscriptions of several species that differ significantly from those used by the first author in the present treatment (most notably A. armata, A. dasyphylla, and A. elata). Trees, small, or shrubs, prickly, or unarmed, rhizomatous herbs, andromonoecious or hermaphroditic. Leaves 1-3-pinnately compound, rachis articulate; leaflets 3-20, entire to serrate, serrulate, crenate, or undulate; stipules connate with petioles at base. Inflorescence terminal or axillary, paniculate, corymbose or umbellate, usually consisting of umbels, capitula, or racemes, occasionally umbels solitary. Pedicels articulate below ovary. Calyx rim 5-dentate. Petals 5, imbricate. Stamens 5. Ovary 5(or 6)-carpellate, occasionally aborted to 3; styles 5, distinct or connate at base. Fruit a berry, ± globose, sometimes 3-5-angular. Seeds laterally compressed; endosperm uniform. | |
