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 disap-
pear 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 trifid-
circular, 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 com-
binetion, Y. acutangula (O. E. Schulz) Y. H. Zhang, is made. Thus, the type of genus Yin-
shania 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. albif-
lora, 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 pinna-
tipartite.
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 Mong-
gol (Ser. Yinshania); and from Sichuan south-eastwards to Guizhou and Hebei (Ser. Henrya-
nae). 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

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. 相似文献

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 . 相似文献

A cytological study reveals the chromosome number of 2n=28 for Siraitia
grosvenori (Swingle) C. Jeffrey ex Lu et Z. Y. Zhang from Yongfu County, Guangxi (fig.
1), which is different from the previous report of 2n=24 (Zou Qi-li et al. 1980). The vou-
cher is deposited in the herbarium of Commission for Integrated Survey of Natural Resources,Academia Sinica. 相似文献

The classical and numerical taxonomy, palynology and the geographical dis-
tribution of the Genus Schizopepon are dealt with in the present paper. Having comme-
nted on various opinions regarding the systematic position of the genus, the present au-
thors consider that C. Jeffrey’s treatment of Schizopepon as a new and monogeneric tri-
be, Schizopeponeae, should be supported.
The gross morphological characters in the genus are assessed from the taxonomic
point of view. Some characters, such as stamens with an elongated connective or not,
different insertions of ovules and various forms of ovaries and fruits, may be used for
distinguishing subgenera.
The pollen grains of all the species were observed under light microscope (LM) and
scanning electron microscope (SEM). The results show that a strong differentiation
has taken place in the pollen of the genus, and in consequence it may be regarded as an
important basis for dividing subgenera and species. Especially it should be pointed out
that degrees of development of colpi and positions of ora are positively correlated with
the external characters used for distinguishing subgenera.
According to the morphological and palynological characters, the genus Schizopepon
may be divided into three subgenera and eight species: 1. Subgenus Schizopepon: 5 spe-
cies, S. bryoniaefolius Maxim., S. monoicus A. M. Lu et Z. Y. Zhang, S. dioicus Cogn.,
S. longipes Gagnep. and S. macranthus Hand.-Mazz.; 2. Subgenus Rhynchocarpos A. M.
Lu et Z. Y. Zhang: 1 species, S. bomiensis A. M. Lu et Z. Y. Zhang; 3. Subgenus Neoschi-
zopepon A. M. Lu et Z. Y. Zhang: 2 species, S. bicirrhosus (C. B. Clarke) C. Jeffrey
and S. xizangensis A. M. Lu et Z. Y. Zhang.
The 8 OTU’s including all the species of this genus and 31 characters, of which 16 are morphological characters and 15 palynological characters, were used in the numerical taxonomic treatment. After standardization of characters, the correlation and distance matrices were computed. The correlation matrices are made to test the various clustering methods. At last, the UPGMA clustering method was selected and its result
is shown in the form of phenogram. The result of numerical analysis is similar to that of the classical classification.
Schizopepon Maxim. is a genus of East Asia-Himalayan distribution. China has all 8 species and 2 varieties, of which 6 species are endemic. Based on the statistics of spedies number, the distribution centre of the genus is considered to be in the Hengduan Mountains (Yangtze-Mekong-Salwin water divides) and the adjacent areas of the southwest China. 相似文献

The present paper deals with 3 genera,Pugionium Gaertn., Lepidium L. and Torula-
ria O. E. Schulz of the family Cruciferae found in the desert regions of China.
Of the genus Pugionium 4 species and 1 new variety and their geographical distribu-
tion are recognized.
Two closely related species of Lepidium, L. apetalum Willd. and L. ruderale L. and
one additional new species are described and their distribution patterns are discussed.
Two species of the genus Torularia previously described by V. Botschantzev (1959)are here redused to varietal ranks, and one additional new species is described. 相似文献

将Plantago erosa Wall. var. fengdouensis Z. E. Zhao & Y. Wang提升为一独立的种，即丰都车前P. fengdouensis (Z. E. Zhao & Y. Wang) Y. Wang & Z. Y. Li。该种由于花冠无毛，花丝着生于花冠近基部，子叶在种子中与腹面（种脐面）相平行，应属于车前亚属subgen. Plantago。丰都车前P. fengdouensis以植株干后变黑和种子较大的特征接近湿生车前P. cornuti Gouan，但其叶具牙齿或羽状锐裂，具3脉，苞片三角状卵形，花冠裂片狭三角形，蒴果纺锤状椭圆球形，近中部周裂，种子腹侧具1纵槽而不同于后者。 相似文献
