关于浙江泡果荠和棒毛荠的分类问题 总被引:4,自引:0,他引:4
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。 相似文献

When the genus Yinshania Ma et Y. Z. Zhao was published, it had
only a single species, Y. albiflora Ma et Y. Z. Zhao which was indicated as the
type of the genus (Acta Phytotax. Sin. 1979). Y. Z. Zhao 155. was indicated as
the type specimen of Y. albiflora. It is adequate to cite Y. albiflora Ma et Y. Z.
Zhao as the type of genus Yinshania Ma et Y. Z. Zhao. In a revision (Acta Phytotax. Sin. 25(3): 204-219, 1987) Y. H. Zhang made a combintion, Yinshania
acutangula (O. E. Schulz) Y. H. Zhang (=Cochlearia acutangula O. E. Schulz)
and reduced Yinshania albiflora Ma et Y. Z. Zhao as a variety of Y. acutangula,i.
e. Y. acutangula var. albiflora (Ma et Y. Z. Zhao) Y. H. Zhang. She is uncorrect,
however, when she cited Y. acutangula (O. E. Schulz) Y. H . Zhang as the type
of the genus Yinshania Ma et Y. Z. Zhao. It should be cited as follows:
Yinshania Ma et Y. Z. Zhao
Typus generis: Yinshania albiflora Ma et Y. Z. Zhao (=Yinshania acutangula(O. E. Schulz) Y. H. Zhang var. albiflora (Ma et Y. Z. Zhao) Y. H. Zhang) 相似文献

十字花科一新属——泡果荠属 总被引:11,自引:2,他引:9
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。 相似文献

Zhang Yu-Hua 《植物分类学报:英文版》1987,25(3):204-219
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. 相似文献

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 相似文献

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. 相似文献

Transposon mediated insertional mutagenesis is one of the approaches for the unique gene cloning. A wild species of Cruciferae family Orychophragmus violaceus (L.) O.E. Schulz, which is of interest for practical breeding as a donor of improved plant oil, was an object of the investigation. Plasmid construction used in the experiments included selective NPT II gene, reported GUS gene serving as an excision marker, structural BAR gene located within the dSpm element and Spm transposase. The GUS gene of this plasmid had not his own promoter and became functional only after Spm-transposition. Transformed Orychophragmus violaceus (L.) O.E. Schulz. plants were obtained by direct mesophyll protoplast transformation as well as Agrobacterium tumefaciens-mediated root explant transformation. Gene transfer and the transposition event were confirmed by the GUS activity and the PCR analysis. Relative transformation efficiency using protoplasts was 5.8%. 相似文献
