卫矛科沟瓣属一新名称

印度支那植物志中有一个假卫矛属植物名称Microtropis poilanei。据其模式标本来看,该种显然不是假卫矛属Microtropis Wallich植物,而是沟瓣属Glyptopetalum Thwaites一新成员。由于种名Glyptope-talumpoilanei Tardieu已经合法发表,笔者根据其模式标本叶全缘的特点,提出新名称为全缘叶沟瓣Glypto-petalum integrifolium Q.W.Lin,Z.X.Zhang & Q.R.Liu。此外由于Microtro pispoilanei未合格发表,作者补充了新名称的拉丁描述。

A Biosystematic Study on Adenophora gmelinii Complex (Campanulaceae)

Seven species were included in this complex before 《Fl. Reip. Pop. Sin.》, which recognized 3 species. Carried out in this work were population sampling ( 46 populations in total), cultivation, experimental observation, chromosome observation (published), crossing, isozymogramatic comparison, character analysis (including numerical taxonomical analysis), stem anatomy and palynological observation. The results are shown as follows. 1. This complex is found almost always out-pollinated as it is always protandrous. No apomixis is found. Seedlings are of only basal leaves in the first year, and it is only in the second year that they develop stems and come into flowering. 2. Among 32 chromosome-counted populations, all in eastern Liaoning, most in western Liaoning and two in Haoxian County of Shanxi Province are found to be 2x (2n=34), and all the others 4x (2n=68). 3. A rather wide range of zymogramatic variation of leaf esterase was detected in the complex. But seed esterase was quite constant. 4. Based on the character analysis (including numerical taxonomical analysis) and stem anatomy, the populations'are found to be different from one another in size and form of corollas, size of fruits, size and indumentum of calyces, size and form of leaves (ratios of length and width), teeth of leaves, relative length of styles and corollas, seed form as well as presence or absence of medullary fibre. As a result, 8 races are recognized. A diploid distributed in western Liaoning, which was recognized as a variety, A. polantha var. contracta, is so distinct in gross morphology that it is treated here as a species, A. contracta (Kitag.) J.Z. Qiu et Hong. With the other 7 races, 3 species (A. gmelinii, A. polyantha and A. elata) and 5 subspecies are recognized. 5. As a result of crossing among 9 populations, some F1 seeds were produced between the tetraploids, but none between the tetraploids and the diploids from eastern Liaoning. 6. Inferred from hybrid index method, the tetraploid populations of A. gmelinii and A. polyantha may have hybridized in eastern Shanxi Province and western Hebei Province, which may explain the intergradation of these two species. The evolution of this complex is finally deduced. Its ancestor might occupy in the past a rather wide area where it differentiated into three diploid races. From the one now distributed in eastern Liaoning, the tetraploid of A. polyantha might have evolved and migrated southwards; from the one in Haoxian (Shanxi), a tetraploid of A. gelinii might have been derived and expanded its area northwards, and finally, its subspecies might have differentiated. No diploid has been found in A. elata. Two diploids might be involved in its origin. One might be the diploid of A. gmelinii, and the other a diploid with calyx teeth (not includedin the complex).

Sporogenesis and Gametogenesis of Endangered Adenophora lobophylla Hong (Campanulaceae)

Reported in this paper are the microsporogenesis, megasporogenesis and the development of male and female gametophytes of the endangered species Adenophora lobophylla. The anther is four-sporangiate with its wall composed of four layers: epidermis, fibrous endothelium, middle layer and glandular tapetum of binucleate cells. The cytokinesis of microspore mother cell in meiosis is simultaneous, and tetrads are tetrahedral. Pollen grains are 2-celled at the dispersal stage. Ovule is anatropous, unitegmic and tenuinucellate with a hypodermal archesporial cell developing directly as the megaspore mother cell which undergoes meiotic division and then forms a linear tetrad. The embryo sac is of Polygonum type. The polar nuclei fuse before fertilization. An endothelium differentiates when the uninucleate embryo sac forms. Comparative studies were made with the closely related and widely distributed species A. potaninii. No differences between them were found. No obstacle to sexual reproduction in this endangered species was observed. As a conclusion, no endangering factors were found to influence the sporogenesis and gametogenesis of A. lobophylla. According to our observision and the references on embryological studies of the Campanulaceae(s. l. ), there is no evident differentiation in sporogenesis and gametogenesis in this family.

He和线萼杜鹃R. linearicupulare Tam处理为南海杜鹃R. westlandii Hemsl.的异名, 鹿角杜鹃R. latoucheae Franch.处理为西施花R. ellipticum Maxim.的异名, R. esquirolii Lévl.处理为长蕊杜鹃R. stamineum Franch.的异名, 山荷桃R. championae Hook. var. ovatifolium Tam处理为刺毛杜鹃R. championae的异名, 并作了相应的讨论。     

直立百部的一个新异名

根据对直立百部Stemona sessilifolia（Miq．）Miq．大量标本的研究和野外调查及引种栽培观察,结合对山东百部Stemona shandongensis D．K．Zang模式标本产地的调查,发现直立百部的形态性状是多变的。研究表明它的习性受生境影响而多变,从直立半灌木到蔓生都有;叶型多变;花通常出自叶腋,而花梗有时与叶柄,甚至主脉合生;内轮花被片大多明显大于外轮。山东百部的形态性状处于直立百部的变异范围内,因此作为独立的种是难以成立的,应处理为直立百部的新异名。     

葡萄属一新名和一新种

描述了自甘肃南部发现的葡萄属一新种,文县蘡薁Vitis wenxianensis W.T.Wang。此新种与特产浙江的三出蘡薁V.bryoniifolia Bunge var.ternata(W.T.Wang)C.L.Li有很近的亲缘关系,二者可能是由蘡薁V.bryoniifolia Bunge衍生而出的一对姊妹群。基于上述认识,将三出蘡薁由变种提升至种的等级,但由于存在一个于1871年发表的种名V.ternata Baker,因此,必须为三出蘡薁拟定一新名。
