江西省种子植物分布新资料

报道江西省植物分布新记录3属6种,为袋果草Peracarpa carnosa (Wall.) Hook. f. et Thoms.、日本对叶兰Listera japonica Bl.、齿爪齿唇兰Odontochilus poilanei (Gagnepain) Ormerod、广东齿唇兰Odontochilus guangdongensis S. C. Chen et al.、革叶茶藨子Ribes davidii Franch.和蒲桃叶冬青Ilex syzygiophylla C. J. Tseng ex S. K. Chen et Y. X. Feng,其中袋果草属Peracarpa Hook. f. et Thoms.、齿唇兰属Odontochilus Blume和对叶兰属Listera R. Br.为江西省新记录属。     

湖南省种子植物3种新记录

报道了湖南省种子植物分布新记录3种,隶属于3科3属,分别为浙江冬青Ilex zhejiangensis C.J.Tsengex S.K.Chen&Y.X.Feng、长匍通泉草Mazus procumbens Hemsl.和纤叶钗子股Luisia hancockii Rolfe。凭证标本均存于中南林业科技大学森林植物标本室(CSFI)。     

Ilex sanqingshanensis sp. nov. (Aquifoliaceae) from Jiangxi Province,China

Ilex sanqingshanensis, a new species of Aquifoliaceae from Jiangxi, China, is described and illustrated with morphological characteristics and ultrastructure of pollen grains. The new species is easily distinguished from the most similar species I. wugongshanensis C. J. Tseng ex S. K. Chen et Y. X. Feng by having smaller leaves that are elliptic, ovate or elliptic‐ovate, with shorter (0.5–1.0 vs 2–3 mm) teeth on the leaf margin, longer pedicels of staminate flowers (2.0–3.5 vs 1.5 mm), smaller pyrenes (3.5–4.0 × 2.0–2.5 vs 4.5–5.0 × 3.0 mm), and woody pyrenes (vs stony pyrenes).     

药用植物苦丁茶与近缘种的微形态研究——叶表皮特征的扫描电镜观察

在扫描电镜下对药用植物苦丁茶 (Ilex kudingcha C.J.Tseng)与 4个近缘种的叶表皮微形态进行了观察。结果显示这些材料的叶表皮仅远轴面有气孔器存在 ,气孔圆形至椭圆形 ,气孔外拱盖表面多平滑 ,拱盖内缘近平滑 ,浅波状或波状 ,外缘角质膜在气孔周围呈环形包着气孔。但各种间叶表皮的微形态特征具有较为明显的差异 ,有一定的分类鉴定意义。本研究结果支持将五棱苦丁茶 (I.pentagona S.K.Chen,Y.X.Feng et C.F.L iang)从苦丁茶中独立出来建立一新种 ,但因苦丁茶具有 2种类型气孔器外缘角质膜排列 ,而不支持对扣树 (I.kaushue S.Y.Hu)与苦丁茶的合并     

苦丁茶与近缘种的果皮微形态特征及其分类学意义

在扫描电镜下对药用植物苦丁茶(Ilex kudingcha C.J.Tseng)与4 个近缘种的果皮微形态进行了观察。结果显示这些材料的果皮上均有气孔器存在, 气孔圆形至椭圆形, 气孔外拱盖表面近平滑或有蜡质碎片, 拱盖内缘近平滑稀浅波状, 外缘角质膜在气孔周围呈环形包着气孔。但各种间果皮的微形态特征具有较为明显的差异, 有一定的分类鉴定意义。本研究结果表明扣树(I.kaushue S.Y.Hu)的果实有指状毛附属物, 不支持与苦丁茶的合并。五棱苦丁茶(I.pentagona S.K.Chen, Y.X.Feng et C.F.Liang)的果皮特征与苦丁茶较近, 但有明显差异, 支持将其从苦丁茶中独立出来建立一新种。     

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。     

国产七种和一变种兰属植物的核型研究

中国清风藤属Sabia Colebr.(清风藤科)的订正

归并了清风藤属5个名称,Sabia campanulata Wall.ex Roxb.var,kingiana Nayar et Majumder处理为S.campanulata Wall.ex Roxb。的异名,S.metcalfiana L.Chen处理为S.leptandra Hook.f.et Thoms.的异名,S.longruiensis X.X.Chen et D.R,Ling和S.swinhoei Hemsl.ex Forbes et Hemsl.ex FOrb.et Hemsl。的异名,S.nervosa Chun ex Y.F.Wu处理为S.coriacea Rehd.et Wils.的异名,订正了缅甸清风藤S.burmania L.chen在中国有分布的错误报道。     

On the Identity of Kudingcha in Chinese Holly (Ilex L.)

An examination of the syntypes, Q. B. Huang 42(IBK) and H. Y. Liang 60355 (IBK, PE, IBSC), cited by C. J. Tseng under his Ilex kudingcha C. J. Tseng, showed that it perfectly agreed with the type specimen(W. T. Tseng 864, US) of I. kaushue S. Y. Hu. So I. kudingcha C. J. Tseng should be treated as the synonym of I. kaushue S. Y. Hu, and the correct name of this important beverage plant(Kudingcha) in China should be I. kaushue S. Y. Hu. Moreover, a new species used as kudingcha, I. pentagona, is described. A key to these two beverage plants and their relatives is offered.

A Study on the Genus Gynostemma Bl. (Cucurbitaceae) from China

The genus Gynostemma B1. consists of 13 species and 2 varieties in the whole world, among which 11 species and 2 varieties occur in China. They are distributed in S. Shaanxi and the southern part of the Yangtze River (including Taiwan province) in China and also in Korea, Japan, Sri Lanka, India and Malesia. Based on the characters and dehiscence of fruit, the genus Gynostemma B1. may be divided into two subgenera, i.e. Subgen. I. Gynostemma and Subgen. II. Trirostllum (Z. P. Wang et Q. Z. Xie) C. Y. Wu ct S. K. Chen, comb. nov. 1. Subgenus Gynostemma. The fruits are baccate, globose, 3-umbonate and incorni culate on the apical side, indehiscent when mature. The style apex in female flower is bifid. Type of subgenus: Gynostemma pentaphyllum (Thunb.) Mak. This subgenus contains 8 species and 2 varieties in the world, among which 6 species and 2 varieties occur in China, i.e.1.G. simplicifolium B1. (Yunnan, Hainan of Guangdong); 2. G. laxum (Wall.) Cogn. (S. Yunnan, Hainan of Guangdong and Guangxi); 3. G. burmanicum King ex Chakr. (Yunnan), 3a. G. burmanicum var. molle C. Y. Wu (Yunnan); 4. G. pentaphyllum (Thunb.) Mak. (S. Shaanxi and the soutern area of the Yangtze River of China), 4a. G. pentaphyllum (Thunb.) Mak. var. dasycarpum C. V. Wu (Yunnan); 5. G. pubescens (Gagnep.) C. Y. Wu, st. nov. (Yunnan); 6. G. longipes C. Y. Wu, sp. nov. (endemic to China: Yunnan, Sichuan, Guizhou, Shaanxi and Guangxi). 2. Subgenus Trirostellum (Z. P. Wang et Q. Z. Xie) C. Y. Wu et S. K. Chen, comb. nov.——Trirostellum Z. P. Wang et Q. Z. Xie in Acta Phytotaxonomia Sinica 19 (4): 483. 1981, syn. nov. The fruit are capsules, subcampanulate, 3-corniculate on the apical side, dehiscent when mature. The style apex in female flower is luniform and irregularly denticulate at margin, rarely bifid. Type of subgenus: Gynostemma cardiospermum Cogn. ex Oliv. This subgenus comprises 5 species, which are all endemic to China. 1. G. yixingense (Z. P. Wang et Q. Z. Xie) C. Y. Wu et S. K. Chen (Jiangsu and Zhejiang); 2. G. cardio spermum Cogn. ex Oliv. (Hubei, Shaanxi and Sichuan); 3. G. microspermum C. Y. Wu et S. K. Chen (S. Yunnan); 4. G. aggregatum C. Y. Wu et S. K. Chen (NW. Yunnan); 5. G.laxiflorum C. Y. Wu et S. K. Chen (Anhui).     

黄芪属一新改级

作者通过对药用黄芪野生资源的调查, 结合查阅大量标本及考证模式标本, 发现淡紫花黄芪Astrasalus membranaceus(Fisch. exLink)Bge. var. membranaceus f. purpurinus(Y. C. Ho)Y. C. Ho不仅花旗瓣顶端为紫红色;而且花小;小叶小, 质地厚, 小叶对数少;果小且果皮厚;限分布于我国西南地区。认为作为亚种处理比较合适。即A. membranaceus(Fisch. exLink)Bge. subsp. pallidipurpureus(Hsiao)X. Y. ZhuetC. J. Chen.     

木兰科植物订正

对部分国产木兰科种类进行了订正,归并7个新异名,澄清Mognolia odoratissima Law et R.Z.Zhou和Michelia sphaerantha C.Y.WuexLaw et Y.F.Wu两个种分类上的混乱。     

国产海桑属植物的两个杂交种

作者通过对红树林海桑属植物进行形态学、花粉学、细胞学以及其它方面的比较研究,证实了拟海桑和海南海桑为两个杂交种,它们的嫌疑亲本分别是杯萼海桑和海桑、杯萼海桑和卵叶海桑·ｓｏｎｎｅｒａｔｉａ×ｈａｉｎａｎｅｎｗｓｉｓｋｏ,ＥＹ．ＣｈｅｎｅｔＷ．Y　Ｃｈｅｎ（ｐｒｏｓｐ）为海南海桑的新名称,而拟海桑S．ｐａｒａｃｓｅｏｌａｒｉｓＫｏ,Ｅ.Ｙ.Ｃｈｅｎ,ｅｔＷ,ＣｈｅｎＹ.Ｃｈｅｎ则被归并入ｓｏｎｎｅｒａｔｉａ×ｇｕｌｎｇａｉＮ.C．Ｄｕｋｅ．     

中国姜黄属植物的订正

将白顶姜黄（CurcumaalbicomaS．Q．Tong）归入川郁金（C．sichuanenslsX．X．Chen),将另一种“川郁金”（C．chuanyujinC．K．HsiehetH．Zhang）归入广西莪术（C．kwangsiensisS．G．LeeetC．F．Liang）。认为过去把莪术鉴定为C．zedoaria（Christ．）Rose．C．caesiaRoxb．或C．aeruginosaRoxb,其实都是C．phaeocaulisVal．的误定;C．elataRoxb．是C．wenyujinY．H．ChenetC．Ling的误定;认为广西莪术的两个变种,即紫脉莪术（C．kwangsiensisvar．affinisY．H．Chen）和毛莪术（C．kwangsiensisvar．puberulaY．H．Chen）不能成立．对台湾是否产C．viridifloraRoxb．表示怀疑。附有中国产姜黄属植物12种的检索表及其分布．     

贡山三尖杉的新名称(Cephalotaxus talonensis Cheng et Feng ex S.G.Lu et X.D.Lang)及分类地位

提议贡山三尖杉的新名称Cephalotaxus talonensis Cheng et Feng ex S.G.Lu et X.D.Lang替代不合法的旧名称Cephalotaxus lanceolata K.M.Feng in Cheng et al.(晚出同名)。对比贡山三尖杉和三尖杉Cephalotaxus fortunei Hooker的模式标本和自然生长状态下的叶片形态,支持将贡山三尖杉处理为种的等级,不赞同Silba(1990)将贡山三尖杉降为三尖杉的变种［Cephalotaxus fortunei Hooker var. lanceolata(Feng) Silba］。文中提供4幅参照图片。     

兰属中若干分类群的订正

基于对许多活植物的观察,对兰科中兰属的若干种类进行了分类学考订,结果承认菅草兰Cymbidium　tortisepalum与峨眉春蕙C. omeiense为独立的种,将春剑C. longibracteatum移至菅草兰之下作为变种,送春C. szechuanicum移至莎叶兰C. cyperifolium之下作为变种。由于春剑、峨眉春蕙和送春的模式标本及引证标本已在30多年前全部丢失,本文指定了新模式。
