Large climber, glabrous throughout. Leaves variable, simple-pinnate with 3-5 leaflets or bipinnate with the lower pinnae bearing 3-5 leaflets each and the upper ones consisting of a single one; leaflets ovate or ovate-oblong, coarsely dentate, subcoriaceous, shortly petiolulate or subsessile, obtuse, round or cordate at base.

13. 廣東蛇葡萄 Ampeiopsis cantoniensis(Hook. & Arn. )Planch.
木質藤本。小枝圓柱形,有縱棱紋,嫩枝或多或少被短柔毛。捲鬚2叉分枝,相隔2節間斷與葉對生。葉為二回羽狀複葉或小枝上部著生有一回羽狀複葉,二回羽狀複葉者基部一對小葉常為3小葉,側生小葉和頂生小葉大多形狀各異,側生小葉大小和葉型變化較大,通常卵形、卵橢圓形或長橢圓形,長3—11釐米,寬1. 5—6釐米,頂端急尖、漸尖或驟尾尖,基部多為闊楔形,上面深綠色,在擴大鏡下常可見有淺色小圓點,下麵淺黃褐綠色,常在脈基部疏生短柔毛,以後脫落幾無毛;側脈4—7對,下面最後一級網脈顯著但不突出;葉柄長2—8釐米,頂生小葉柄長1—3釐米,側生小葉柄長0—2. 5釐米,嫩時被稀疏短柔毛,以後脫落幾無毛。花序為傘房狀多歧聚傘花序,頂生或與葉對生;花序梗長2—4釐米,嫩時或多或少被稀疏短柔毛,花軸被短柔毛;花梗長1—3毫米,幾無毛;花蕾卵圓形,高2—3毫米,頂端圓形;萼碟形,邊緣呈波狀,無毛;花瓣5,卵橢圓形,高1. 7—2. 7毫米,無毛;雄蕊5,花藥卵橢圓形,長略甚於寬;花盤發達,邊緣淺裂;子房下部與花盤合生,花柱明顯,柱頭擴大不明顯。果實近球形,直徑0. 6—0. 8釐米,有種子2—4顆;種子倒卵圓形,頂端圓形,基部喙尖銳,種臍在種子背面中部呈橢圓形,背部中棱脊突出,表面有肋紋突起,腹部中棱脊突出,兩側窪穴外觀不明顯,微下凹,周圍有肋紋突出。花期4—7月,果期8—11月。
產安徽、浙江、福建、臺灣、湖北、湖南、廣東、廣西、海南、貴州、雲南、西藏。生山谷林中或山坡灌叢,海拔100—850米。模式標本采自香港。
本種葉形、大小變化甚大,甚至有時在同一植株上部小枝上小葉較小,下部小枝的小葉較大,因此過去一些學者在標本室中把具有大葉的標本鑒定為羽葉蛇葡萄 A. chaffanjoni(Lévl. & Vant. )Rehd. ,把小葉者鑒定為本種,但不同於前者在於,花軸被短柔毛,葉下面淺黃褐色,最後一級網脈清晰可見但並不突出,葉片上面在擴大鏡下有淺色小圓點,頂生小葉大多比側小葉寬且為倒卵形,種子窪穴不明顯,僅微下凹。
