通过标本检查, 发现毛茛科加查银莲花(Anemone jiachaensis W. T. Wang)与西藏银莲花(A. tibetica W. T. Wang)属于同一种植物, 故将前者处理为后者的异名。加查银莲花发表时被置于鹅掌草组[A. sect. Stolonifera (Ulbr.) Juz.], 但其花粉为三沟而非多沟, 与岩生银莲花亚组[A. subsect. Rupicolae (Tamura ex Chaudhary & Trifonova) Starod.]的岩生银莲花(A. rupicola Camb.)(西藏银莲花亦属于该亚组)的花粉类型一致, 而与鹅掌草组植物的多沟花粉明显不同, 从而进一步表明加查银莲花与西藏银莲花确为同一种植物而且应为岩生银莲花亚组的成员。  相似文献

该文对中国毛茛科银莲花属(Anemone L.)进行了分类学研究,共收载86 种,可将这些种划分为10 组:其中5 组,即草玉梅组、西南银莲花组、钝裂银莲花组、短柱银莲花组和直果银莲花组均是该属具中等演 化水平的分类群;另外5 组,即银莲花组、鹅掌草组、卵叶银莲花组、二岐银莲花组和打破碗花花组则均是具 高度演化水平的分类群。 在这10 组中,钝裂银莲花组与银莲花组有相近的亲缘关系,短柱银莲花组与鹅掌 草组有相近的亲缘关系,而其余6 组之间的亲缘关系情况,目前尚未了解。 该文写出了区别所有属下分类 群的检索表、所有分类群的文献引证和地理分布,并对每一种均指出了研究的重要标本,对多数种均提供插 图。 描述了2 新组(短柱银莲花组和直果银莲花组)、4 新系(鹅掌草组的鹤峰银莲花系和加查银莲花系,以 及直果银莲花组的兴义银莲花系和直果银莲花系)、13 新种(九龙银莲花、柏枝山银莲花、狭萼银莲花、道孚 银莲花、泸定银莲花、波密银莲花、嘎隆拉山银莲花、三小叶银莲花、折多山银莲花、宝兴银莲花、贡嘎银莲 花、福贡银莲花和盘蕊银莲花)、1 新亚种(长柄钝裂银莲花)以及4 新变种(紫萼折多山银莲花、矮展毛银莲 花、疏毛川西银莲花和泸水银莲花)。 此外,还将变种条叶银莲花提升为种级分类群;将涪陵银莲花降级作 为川西银莲花的一个变种;由于Anemone rupestris Hook. f. & Thoms. 为一不合法的晚出异物同名,遂拟出一 新名(Anemone neorupestris W. T. Wang);小花草玉梅在过去多年间被处理为草玉梅的一个变种,在该文中其 原来种级群的地位得到恢复;1939 年,H. Handel ̄Mazzetti 将变种云南银莲花归并于展毛银莲花,将稀果银莲 花归并于滇川银莲花,对此二归并,该文赞同并采用。  相似文献

该文描述了自云南西北部发现的毛茛科银莲花属一新组,即维西银莲花组(sect. Deinostigma)和一新种,即维西银莲花(Anemone weixiensis)。此组与卵叶银莲花组有亲缘关系,与后者的区别在于其心皮较少(约11枚),子房被短柔毛,柱头明显,呈椭圆体形,瘦果被短柔毛,不扁,无肋,顶端具椭圆体形宿存柱头。  相似文献

In the present paper, a new sect. Leptothece W. T. Wang & Bing Liu wih its only new species, Anemone xiaowutaishanica W. T. Wang & Bing Liu, of the genus Anemone is described and illustrated. In having vertical rhizome, rosulate leaves, 1-flowered cyme, sessile involucre bracts, linear stamen filaments, tricolpate pollen grains with spinulose tectum, and subulate styles, sect. Leptothece is related to sect. Himalayicae (Ulbr.) Juz. From the latter it differs in its 3-parted or 3-sect involucre bracts, 3 carpels per flower, and strongly bilaterally compressed ovary, and with these advanced characters it is remarkably more advanced than sect. Himalayicae, and might be derived from the latter. Anemone xiaowutaishanica with its small distribution area restricted to a valley in the Mt. Xiaowutai, Hebei Province, China is obviously a stenochoric species, and on the basis of its advanced morphological characters it may be regarded as a neoendemic.  相似文献

Anemone fulingensis W. T. Wang & Z. Y. Liu, a new species of the Ranunculaceae discovered from Fuling, Chongqing, China, is described and illustracted. In having sessile involucre bracts, 4-5-sepalled flowers, filiform filaments, and pantocolpate pollen it should be a member of Anemone sect. Stolonifera (Ulbr.) Juz., and from all other species of that section differs in its peculiar moniliform rhizome consisting of 2-10 tubers. In view of the fact that in Anemone the tubers are present in certain different evolutionary lines, and their appearance is a secondary phenomenon, this new species should be considered advanced in sect.
