摘　　要：番荔枝科(Annonaceae)是基部被子植物木兰目(Magnoliales)中较进化且物种数最多的科。目前的系统发育研究将番荔枝科划分为4个亚科,即蒙蒿子亚科(Anaxagoreoideae)、澄光木亚科(Ambavioideae)、番荔枝亚科(Annonoideae)和排石木亚科(Malmeoideae),有107属,2400多种,中国原产21属约110种。番荔枝科泛热带分布,是热带植物区系的优势类群,中国云南盈江位于云南省最西部边境,与缅甸东北部接壤,并与印度的东阿萨姆较近,植物区系处于东南亚(印度—马来西亚)热带生物区系向东亚亚热带-温带生物区系的过渡地带,属典型热带北缘性质,在植被地理和生物地理上十分重要,成为生物多样性保护的关键和热点地区。该区的热带雨林是印度阿萨姆和缅甸北部的热带雨林向东和向北扩散分布的边缘类型,是东南亚热带雨林在纬度和海拔分布上的极限类型。该文报道了采自中国云南省盈江县,引种保存于中国科学院西双版纳热带植物园的番荔枝科哥纳香属2个中国新记录种,即皱叶哥纳香[Goniothalamus sesquipedalis(Colebr.ex Wall.)Hook.f.&Thomson]和长梗哥纳香(G.peduncularis King&Prain)。Flora of China将盈江哥纳香(G.lii X.L.Hou&Y.M.Shui)处理为云南哥纳香(G.yunnanensis W.T.Wang)的异名,基于活植物观察、馆藏标本和文献研究,该文对盈江哥纳香的分类地位进行了澄清,将其处理为长梗哥纳香的异名。皱叶哥纳香原记载产于印度、孟加拉国和缅甸等地,长梗哥纳香仅产于缅甸,该文对它们进行了补充描述,并提供彩色图版以便于鉴别。凭证标本存放于中国科学院西双版纳热带植物园标本馆(HITBC)。哥纳香属2个新记录的发现,丰富了中国番荔枝科植物多样性的认识,为中国云南热带植物区系属于热带亚洲(印度—马来西亚)植物区系,以及与缅甸北部、印度东北部植物区系的关系增加了例证。Goniothalamus sesquipedalis(Colebr.ex Wall.)Hook.f.&Thomson andG.peduncularisKing&Prain are reported as two new records for the flora of China,the two species were found in Yingjiang County,Yunnan Province,China and conserved in Xishuangbanna Tropical Botanical Garden.G.liiX.L.Hou&Y.M.Shui has been treated as synonym withG.yunnanensisW.T.Wang inFlora of China.Here,we clarified its taxonomical status and treated as a new synonym withG.peduncularisbased on living plants observation,the type specimens and the literatures revision.G.sesquipedaliswas previously known from India,Bangladesh and Myanmar,andG.pedunculariswas only in Myanmar.In this paper,we update the description and illustrate them based on the herbarium specimens and living collections.The voucher specimens are deposited in the Herbarium of Xishuangbanna Tropical Botanical Garden(HITBC).
