A Revision of Genus Yinshania (Cruciferae)

The genus Yinshania was established by Ma Yu-chuan and Zhao Yi-zhi in 1979, when only one species, Y. albiflora Ma et Y. Z. Zhao, was discribed from Nei Monggol. In the present paper the genus Yinshania is revised and four new species, two new varieties and four new combinetions are reported. There are so far eight species and two varieties in total in this genus. Important morphological characters of the genus are analysed, which shows that the lateral nectariferous glands positioned at lateral base of the brevistamens are triangularovoid; there are dense minute pustules on the surface of valves, which is easily neglected because the pustules disappear or shrinked when dry; simple or furcate hairs are present in the most species, seldom absent; the shape of pollen grains is relatively steady, elliptic or long-elliptic, with the polar view trifidcircular, the equatorial view elliptic or long elliptic, the aperture 3-colpate, exine reticular. The type of genus Yinshania is changed. Cochlearia acutangula O. E. Schulz was published in 1929, but Y. albiflora Ma et Y. Z. Zhao in 1979. They are the same species and a new combinetion, Y. acutangula (O. E. Schulz) Y. H. Zhang, is made. Thus, the type of genus Yinshania should be changed to Y. acutangula (O. E. Schulz) Y. H. Zhang. Besides, He Ye-qi 6121 (paratype, PE), which is different from Y. acutangula var. albiflora, is separated from it and transferred the typical variety, Y. acutangula. According to the characters of fruit shape the genus Yinshania is divided into two sections, namely, Sect. Microcarpa and Sect. Yinshania, and then Sect. Yinshania is subdivided into two series. Sect. 1. Microcarpa. Silicles widely ovoid or subglobose, 1-2.2 mm long, 0.8-2.2 mm wide, the ratio of length and width about 1.1. Sect. 2. Yinshania. Silicles oblong, oblong-ovoid or long-lanceolate, ellipsoidal, 1.5-4.5 mm long, 0.3-1.5 mm wide, the ratio of length and width about 2.5-3.3. Ser. 1. Henryanae. Raches flexuose; plants densely hairy; leaves 3-5-foliolate, seldom pinnatipartite or pinnatisect. Ser. 2. Yinshania. Raches non flexuose; plants sparsely hairy; leaves pinnatisect or pinnatipartite. The genus Yinshania is a genus endemic to China, with their range from eastern Xizang to western Hubei from northern Guizhou to central Nei Monggol. The taxa are mostly of a small area. Sect. Microcarpa is concentrated in Sichuan and southern Gansu; Sect. Yinshania is spread from Xizang and Sichuan, nouthwards to Gansu, Ningxia, Shanxi, Hebei and Nei Monggol (Ser. Yinshania); and from Sichuan south-eastwards to Guizhou and Hebei (Ser. Henryanae). There are five species in Sichuan. The present paper conjectures that the distribution centre of the genus is in the Hengduan Mountains and its adjacent areas.     

On the Identity of Yinshania albiflora

The author examined the type of Cochlearia acutangula O.E.Schulz, G. Giraldi 2423, and found that Yinshania albiflora is conspecific with the former. Therefore the reduction of Yinshania albiflora(=Yinshania acutangula var. albiflo-ra) to Yinshania acutangula as a synonym is made.     

泡果荠属和阴山荠属（十字花科）的分属界限及两属的分类校订

泡果荠属Hilliella和阴山荠属Yinshania是十字花科中国特有的两小群植物,但是,它们的分属界定却一直颇有争议。本文结合前人的研究结果重新对这两群植物做了研究,从而进一步确认这两群植物应该界定为两个属,即泡果荠属和阴山荠属。文中比较了两属间重要的性状特征,并指出它们的主要区别在于:泡果荠属果实无假隔膜,种子较大,表面具小瘤状突起,染色体倍性为六倍体（2n=6x=42）;而阴山荠属果实有假隔膜,种子较小,表面具网纹,染色体倍性为二倍体（2n=2x=12）。两属其他方面如叶形态、叶表皮结构、被毛类型

阴山荠属,泡果荠属,棒毛荠属和岩荠属的扫描电镜观察

以阴山荠属、泡果荠属、棒毛荠属和岩荠属的18种植物取用实验材料,对果实外表皮、种子外种皮、毛和花粉粒等特征鉴别器官进行扫描电镜观察,提供36张照片资料,并以检索性状比较属间特征,证明该4属作为各自独立的属是恰当的。     

The Identification and Revision on the Type of Cochleariopsis Y. E. Zhang (Cruciferae)

The genus Cochleariopsis Y.H. Zhang was described in 1985, with C. zhejiangensis Y. H. Zhang, the only member of the genus, as its type. However, this species had been published by O.E. Schulz earlier in 1923, named Cochlearia warburgii O.E. Schulz. Hence, this species is not new one, and the type of the ge-nus should be Cochleariopsis warburgii (O. E. Schulz)L. L. Lu .     

关于浙江泡果荠和棒毛荠的分类问题

再次对浙江泡果荠Hilliella warburgii和棒毛荠Cochleariella zhejiangensis作比较研究后,本文认为：两者差别明显,尤其是后者子房和果实表面密被发达的膜质棒状毛,又有各自不同的地理分布区,显然是不同属植物。棒毛荠属(单型属)的属名模式是Cochleariella zhejiangensis Y．H．Zhang et R．Vogt。     

十字花科一新属——泡果荠属

岩荠属泡果荠组植物(Cochlearia L.Sect.Hilliella O.E.Schulz)不仅在体态上而且在其它一系列特征特别是具泡状突起的果实特征上极不同于狭义的岩荠属(Cohc-learia L.s.str.),松蓝叶岩荠属[Glaucocochlearia(O.E.Schulz)Pobed.],以及拟常绿岩荠属[Pseudosempervium(Boiss)Grossh.]。这些特征看来可以作为建立一新属的根据,因此将其提升为一独立的属并把这一组的8个种组合到新属中去。

On the taxonomy of Phlegmariurus (Herter) Holub sect. Huperzioides H. S. Kung et L. B. Zhang (sect. nov.) with notes on the infrageneric classification of the genus Phlegmariurus in China

After the genus Phlegmariurus (Herter)Holub was proposed by J. Holub 1964, the repercussions are different, with some botanists accepting it, while others refusing. We take it as a separate genus since the related species from China are distinctly different from those of Huperzia Bernh. The plants of this genus in China are classified into three sections: Sect. Huperzioides H. S. Kung et L. B. Zhang, sect. nov.; Sect. Carinaturus (Herter)H. S. Kung et L. B. Zhang, comb. nov. and Sect. Phlegmariurus. A key to sections is given. The taxonomy on the new section, Sect. Huperzioides, is presented. Thirteen species are reported in China, involving 4 new combinations: Ph. petiolatus (Clarke)H. S. Kung et L. B. Zhang, Ph. cryptomerianus (Maxim.)Ching, Ph. ovatifolius (Ching)W. M. Chu, Ph. nylamensis (Ching et S. K. Wu)H. S. Kung et L. B. Zhang; and 7 names are considered for the first time as synonyms: Huperzia formosana Holub [ = Ph. taiwanensis Ching ], H. austrosinica Ching [ = Ph. petiolatus ], Lycopodium mingchgense Ching [ = Ph. mincheensis Ching ], Ph. mincheensis var. angustifolius C. Y. Ma [ = Ph. mincheensis ], Ph. longyangensis C. Y. Ma [ = Ph. fordii ], Ph. nanus C. Y. Ma [ ＝ Ph. fordii ], Ph. yandongensis Ching et C. F. Zhang [ ＝ Ph.fordii]. One new record in China is found: Ph.hamiltonii.     

阴山荠属的研究

本文为阴山荠属和泡果荠属的分类研究提供了染色体数目试验结果。受试种类按染色体数目的分异形成两大类群,与按形态地理分类法得出的结果一致。阴山荠属(Yinshania):柔毛阴山荠Y.henryi,2n=12;叉毛阴山荠Y.fur-catopilosa,2n=12;乾宁阴山荠Y.qianningensis,2n=12;泡果荠属(Hiliela):昌化泡果荠H.changhuaensis.2n=42,奇异泡果荠H.paradoxa,2n=42;双牌泡果荠H.shuangpaiensis,2n=44;弯缺泡果荠H.sinuata,2n=44;黟县泡果荠H.yixianensis,2n=42。染色体数目结合形态学和地理分布研究,支持两属作为各自独立的属存在。本属是中国特有分布属,形态演化研究表明,本属阴山荠组是较原始的类群,小果组是较进化的类群。文中讨论了属中各种的分布规律和全属的分布特点,认为川西及其邻近地区是本属多样化中心和近代分布区中心,本属可能是从该地区,并随着新生代第三纪喜马拉雅造山运动和青藏高原的崛起,以及第四纪冰期、间冰期的迭次变化产生的全球性气候波动而分化迁移。本属基本上属亚热带、暖温带的半湿润半干旱生态类型。根据本属重要器官较稳定的特点,以及地区性特有成分较高的特点,认为本属是较古老的中国特有成分     

竹亚科刚竹属植物的修订(Ⅴ)

在模式材料、实物照片或采集物观察比较以及实地考察的基础上,结合原始描述,对竹亚科Bambusoideae刚竹属Phyllostachys Sieb.et Zucc.中最后一批存疑或悬而未决的拉丁双名进行了考订。分别将彭县刚竹P.sapida并入石绿竹P.arcana,P.balansae并入桂竹P.bambusoides,金竹仔P.subulata并入寿竹P.bambusoides f.shouzhu,广州刚竹P.cantoniensis并入水竹P.heteroclada,大节刚竹P.lofushanensis和刺芒刚竹P.aristata均并入笔笋竹P.nidularia f.basipilis,贵州刚竹P.guizhouensis并入毛金竹P.nigra var.henonis,台湾石竹P.lithophila并入刚竹P.sulphurea var.viridis,均作为异名处理;讨论了产于越南的3个种的归属问题,推测P.caobangensis可能与桂竹P.bambusoides为同种,而P.baccanensis和P.vietbacensis可能均与假毛竹P.kwangsiensis为同种。     

长江三峡库区诸葛菜属(十字花科)一新种

采于长江三峡库区一个植物新种,属于十字花科,与诸葛菜(Orychophragmus violaceus (L.) O.E.Schulz)相比较,其特点为柔弱草本,多分枝,茎生叶为间断羽状复叶或羽状复叶,种子为圆柱状长圆形,表面网状,命名为秭归诸葛菜(Orychophragmus ziguiensis Z．E．Zhao et J．Q．Wu)。     

中国橐吾属(菊科-千里光族)的分类学研究(五):君范橐吾、长毛槖吾和南川橐吾原白中一些排印错误的改正

对我国菊科橐吾属(Ligularia Cass.) 3种植物原白中模式标本引证的排印错误进行了改正。君范橐吾(L. lingiana S.W. Liu)原白中错误地将主模式标本引证为赵清盛82946,实际应为赵清盛、牟克平和杨亚斌8294。长毛槖吾(L. changiana S.W. Liu ex Y. L. Chen & Z. Yu Li)(=L. heterophylla C. C. Chang,为L. heterophylla Rupr.的晚出同名)主模式为蔡希陶59771,但L. heterophylla C. C. Chang 的原白中错误地将主模式标本引证为蔡希陶59711;该号标本属于唇形科的灯笼草[Clinopodium polycephalum (Vaniot) C. Y. Wu & Hsuan]。南川橐吾(L. nanchuanica S. W. Liu)原白中引证的副模式标本熊济华和周子林93871实际应为李国凤63871,前者属于桤叶树科的城口桤叶树(Clethra fargesii Franch.)。
