摘要: 三裂枫Acer calcaratum Gagnep.和长裂枫Acer acuminatum Wall. ex D. Don两种分布于东南亚和喜马拉雅地区的珍稀树种, 最近分别发现在我国云南和西藏有分布, 属于我国新记录种。三裂枫属于广义鸡爪槭组sect. Palmata中华槭系ser. Sinensia, 主要形态特点为叶片三裂, 叶片基部圆形, 伞房花序, 通常只有一个发育完全的果实, 坚果近卵球形。长裂枫属于尖齿槭组sect. Arguta, 主要特点为叶片3裂和5Acer calcaratum and A. acuminatum, two poorly known and very rare species, occurring in Southeast Asia and the Himalayas respectively, were discovered recently in Yunnan Province and Xizang (Tibet) Autonomous Region in China. Acer calcaratum belongs to sect. Palmata ser. Sinensia, and is characterized by its 3 basally-nerved and 3-lobed leaves, with a rounded base, short, corymbose inflorescence and with few fruits, usually with only one large, well-developed samara, the nutlet more or less ovoid. Acer acuminatum belongs to sect. Arguta, and is characterized by its 3- or 5-lobed leaf blade, the lateral lobes usually as long as central lobe, apex of the lateral lobes caudate-acuminate, and infructescence 12–20 cm long.Decontaminated thianthrene disproportion.
