描述了番荔枝科一新种——版纳野独活Miliusa bannaensis X. L. Hou,并绘了形态图。本种以其较大(长2 cm,直径达2.5 cm)的花近于大果野独活M. macrocarpa Hook. f. & Thoms.,但以其较短(长10 mm)的花梗、较小(直径8-9 mm)的小果和卵状长圆形或倒卵状长圆形的叶易于区别。本种也以其较大(长14-22 (-26) cm, 宽6.5-10 cm)的叶相似于绒毛野独活M. velutina (Dunal.) Hook. f. & Thoms.,但  相似文献

目的:对独活寄生汤联合来氟米特片治疗类风湿关节炎的临床疗效进行观察。方法:对独活寄生汤联合来氟米特片治疗类风湿关节炎(肝肾亏虚型)的临床疗效进行回顾性分析;应用随机数字表把纳入的120例患者随机分为治疗组和对照组,两组各60例,对照组给予来氟米特片治疗;治疗组予以独活寄生汤联合来氟米特片治疗,1疗程为6个月,分别于治疗前、治疗1个月、2个月、3个月对患者进行DAS-28评分并采用HAQ健康评估问卷进行生存质量评估。结果:治疗组总有效率、显效率分别为88.33%和80%;对照组总有效率、显效率分别为73.33%和61.61%。总有效率、显效率治疗组均显著优于对照组。两组患者HAQ评分、DAS-28评分在治疗1个月均有所改善,病情得到控制;两组患者HAQ评分、DAS-28评分在2个月后仍继续减少,病情初步缓解,较本组治疗前有显著性差异(P0.05),组间相比仍无显著性差异(P0.05);两组患者在治疗结束时HAQ评分、DAS-28评分明显减少,病情完全控制,较本组治疗前及治疗1个月有显著性差异(P0.05),组间相比均有显著性差异(P0.05)。结论:独活寄生汤联合来氟米特片可有效改善肝肾亏虚型型类风湿关节炎患者的临床症状及实验室指标,且无明显不良反应,提高生存质量,取得了满意效果。  相似文献

本文首次报道了我国独活属10种(含1变种)的核型,其中8种的染色体数目亦为首次报道。研究表明它们的染色体数目均为2n=2x=22,为二倍体,其核型为中部着丝点和亚中部着丝点染色体组成,仅具1A和2A两种类型。有4种具随体染色体,在部分H.vicinum植株中发现有1条B染色体,在H.millefolium var.longilobum中同时存在2n=22和2n=24的非整倍体.不同种的染色体形态不同,为分类研究提供了细胞学依据。    本文在核型分析基础上讨论了该属分类群的划分、种间亲缘关系及演化,并结合我国毗邻地区该属细胞学资料和地理分布规律,提出我国西南部的横断山区是独活属的频度中心和多样性中心。  相似文献

现代西方文明尽管已发展到一定程度,但社会对女性的歧视依然存在,女权主义团体的日益增多.试图从英语的词汇入手,分析英语词汇对女性的歧视和贬低.第一部分阐述英语词汇通常给人某种暗示,认为女人通常都是男人的一部分;第二部分则揭示英语词汇本身对女性的一种天生的敌意,它不断地歧视贬低女性.只要社会中的性别歧视未被消灭,语言中的歧视现象就永远不会消失.  相似文献

Some species of Hemerocallis were cultivated in the campus of Futan Un- iversity, including the evergreen H. aurantiaca Baker.  The original plant of H. auran- tiaca was introduced from Zhangzhou, southeastern Fukien Province.  The karyotype formula of H. aurantiaca is 2n=33=12m+9sm+3st+3T+6m(sat).   The  karyotype differs from those of summer-green or evergreen H. fulva (k(2n)=33=3M+21m+6sm +3T) and H. fulva var. kwanso (K(2n)=33=3M+l8m+6sm+3st+3T).  The vouchers are kept in FUS.  相似文献

The present paper reports the first record of the eGnus Stachyphryni- um, Marantaceae, in China.  It is characterized by solitary spikes, elongated and erect with impricated bracts.  The inflorescence arises from a short stem on the rhizome.       In this genus there are 14 species in total.  They are distributed from Sri Lanke to Java and Borneo, through Indo-China Peninsula, Malay Pennisula.  Its distribution center is in Indo-China Penninsula and Malay Penninsula.  The north limit lies in sou- thern Yunnan of China. Most species of the genus have a stenochorie area, for example, S. zeylanicum is endemic to Sri Lanka; S. latifolium occurs in Java only and so on.      A New species, S. Sinense H. Li, to China, is illustrated and described in Latin.  相似文献

五种黄芪属植物的核型分析   总被引:1,自引:0,他引:1  
The karyotypes of five species in Astragalus (A. dahuricus DC., A. mongolicus Bunge., A. adsurgens Pall., A. melilotoides Pell., A. huangheensis H. C. Fu., Y. H. Liu) were studied.  Among them, the karyotypes of A. dahuricus and A. melilotoides are re- ported for the first time.  While A. melilotoides is tetraploid (2n=4X=32), all the others are found to be diploid (2n= 2X = 16).  Based on the comparison of karyotypes, the evolu-tionary order of these 5 species is discussed.  相似文献

阴山荠属的校订   总被引:1,自引:0,他引:1  
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
