中国香港新记录的十个分类单元

中国香港位于热带北缘,其植被在历史上曾遭到大规模破坏,近几十年来逐渐恢复。香港植物标本采集有很长的历史,迄今为止已记录的维管植物超过2 170种,然而新种和新分布仍在不断增加。在最近的野外工作中,作者发现10种在香港新记录到的维管植物,分别是唇边书带蕨[Haplopteris elongata (Swartz) E. H.Crane]、雷公连[Amydrium sinense (Engl.) H. Li]、百足藤[Pothos repens (Lour.) Druce]、四川轮环藤(Cycleasutchuenensis Gagnep.)、山黑豆(Dumasia truncata SieboldZucc.)、倒心叶珊瑚[Aucuba obcordata (Rehder) Fu ex W. K. Hu et Soong]、竹叶榕(Ficus stenophylla Hemsl.)、长叶冠毛榕[F. gasparriniana var. esquirolii (H. Lév.Vaniot) Corner]、硬叶冬青(Ilex ficifolia C. J. Tseng ex S. K. Chen et Y. X. Feng)、假福王草[Paraprenanthes sororia(Miq.) C. Shih.]。雷公连属(Amydrium Schott)、山黑豆属(Dumasia DC.)和假福王草属(Paraprenanthes C. C.Chang ex C. Shih)为香港的新记录属。以上的发现不仅丰富了香港的植物区系,而且表明保护残存植被非常重要,且极小种群的保护也值得特别关注。

四川乌头属的修订

四川是我国乌头属Aconitum L.植物的重要分布区。本文对该地区的乌头属植物进行了分类修订。通过文献查阅、野外观察和标本室研究,对乌头属的形态性状在居群间和居群内的变异式样进行了比较分析,发现叶分裂程度、上萼片的形状和花梗毛被等性状是较为可靠的分种依据,但是在个别情况,这些性状也会在同一种的同一居群内或不同居群间发生变化。花瓣和种子的特征对于属下划分有重要意义。本文承认四川乌头属植物有46种11变种,另有2种和1变种暂存疑。29种和22变种降为异名;作出新组合2个,其中包括1个改级新组合。紫乌头A. delavayi Franch.和保山乌头A. nagarum Stapf为四川新分布记录。对康定乌头A. tatsienense Finet &; Gagnep.、川鄂乌头A. henryi Pritz.和狭裂乌头A. refractum (Finet &; Gagnep.) Hand.-Mazz.进行了后选模式的标定。初步澄清了东俄洛乌头A. tongolense Ulbr.和狭裂乌头等种类中长期存在的名实混乱。还给出了各个种的形态描述、地理分布以及分亚属、分系和分种检索表。

山茶科紫茎属和舟柄茶属的系统学研究

本文对山茶科紫茎属和舟柄茶属进行了深入细致的系统学研究,藉助形态学、古植物学、孢粉学,细胞学和解剖学资料澄清了两属的分合问题,证实两属在各方面具有较大相似性,并且各分类特征存在广泛的联系而无法分开,从而赞同H．K．Airy Shaw,J．R．Sealy及S．A.Spongberg的主张,即将这两属合并。在此基础上本文提出了世界范围广义紫茎属下分类系统。属下新系统根据花柱合生程度、花序类型,苞片与萼片的形状以及两者的相对长度等特征,分为两个亚属,五个组,同时对该属种类进行修订。该属共有23种5变种,本文发表新组1个,新名称2个,新组合9个,新异名10个,新种1个,并附有分种检索表。广义的紫茎属为东亚-北美间断分布类型,中国南部和西南部是该属的起源中心和高度分化中心。根据化石资料推断,该属起源于早白垩纪,在第三纪以前于整个劳亚古陆上呈广泛而连续的分布,后因冰川及造山运动的影响,从而形成现在的分布格局。
