Aristolochia Subgen. Pararistolochia ( Hutch. & Dalz. ) O. C. Schmidt, a smallest one among so far known three subgenera in the genus, often treated as a separate genus, is composed of only nine species from Tropical Africa (8 species)and Tropical Asia ( l species). This work deals mainly with the system and taxonomic treatment as well as distribution based on the herbarium materials form British Museum (Natural History) (BM), National Botanical Garden of Belgium(BR), Royal Botanic Gardens of Kew(K) and Laboratoire de Phanerogamie of Paris(P). Three sections in the subgenus are described as new by the number of anthers and its arrangement. Also two names, Pararistolochia zenkeri (Engl.) Hutch. & Dalz. and P. macrocarpa (Duch.) Poncy var. soyauxiana(Oliv. )Poncy, are reduced to synonyms of A. macrocarpa Duch.; andone name, A. preussii Engl., is reduced to a synonym of A. promissa Mast.  相似文献

Haplodontium zangii X.R.Wang &; J.C.Zhao, a new moss species from Xizang, China, is described and illustrated. Previously, specimens of H. zangii have been identified as Mielichhoferia himalayana Mitt. However, H. zangii is distinctly different from M. himalayana in having excurrent costae with short awns (vs long denticulate awns), short-pyriform capsules, 0.8–1?mm (vs long-pyriform capsules, 2.5–3?mm), and densely papillose exostome teeth (vs smooth or vertically striped exostome teeth). Haplodontium zangii is similar to H. macrocarpum (Hook.) J.R.Spence, which was traditionally placed in Mielichhoferia Nees &; Hornsch. as M. macrocarpa (Hook.) Bruch &; Schimp. The main differences between H. zangii and H. macrocarpum are in the morphology of the leaves, capsules, guide cells, and stomata. Mielichhoferia himalayana and another Chinese species of Mielichhoferia, M. sinensis Dix., are also transferred to Haplodontium Hampe, a new genus in the bryoflora of China, as H. himalayanum (Mitt.) X.R.Wang &; J.C.Zhao and H. sinensis (Dix.) X.R.Wang &; J.C.Zhao. A morphological comparison and a key to the three species of Haplodontium in China as well as to H. macrocarpum, a species that is likely to be found in China, are provided.  相似文献

It is argued that the original material of Maerua macrocarpa consists of elements from three different species: M. denhardtiorum, Thilachium thomasii and Capparis tornentosa . A lectotypification is proposed that makes M. macrocarpa a synonym of M. denhardtiorum .  相似文献

Authentic herbarium material of Crataegus calycina Petermann (1849) supports Hrabetová-Uhrová's contention in 1969 that this is conspecific with C. macrocarpa Hegetschweiler; the name C. calycina , for which a Petermann specimen in Musée Botanique Cantonal, Lausanne is designated as lectotype, had been incorrectly applied in Flora Europaea.
Examination of the specimens in the Linnaean Herbarium has led to acceptance of Dandy's proposal in 1946 that sheet 643.12 should be designated as the lectotype of C. oxyacantha L. (1753). This specimen is not, as frequently assumed, C. laevigata (Poiret) DC. (C oxyacanthoides Thuill.) but the species described in Flora Europaea as "C. calycina Peterm. subsp. curvisepala (Lindman) Franco". It is suggested that the name C. oxyacantha L. is a source of confusion and should be rejected under Article 69 of the International Code of Botanical Nomenclature. This gives priority to the name C. curvisepala Lindman, which should replace C. calycina Peterm. in Flora Europaea.  相似文献

描述了我国广西大苗山莎草科Cyperaceae一新种——大苗山薹草Carex damiaoshanensis X. F. Jin & C. Z. Zheng。本种形态上与花葶薹草C. scaposa C. B. Clarke接近, 区别主要在秆、秆生叶和支花序轴均无毛, 支花序数较少, 小穗疏生雌花。对秆、支花序梗、秆生叶和小坚果扫描电镜观察也显示了这二者的区别。  相似文献

Carex damiaoshanensis X. F. Jin & C. Z. Zheng, a new species of Cyperaceae from Guangxi, China, is described and illustrated. This new species resembles C. scaposa C. B. Clarke in its arundinaceous leaves and spikes arranged in a compound panicle, but differs from the latter in having glabrous culms, cauline leaves, and rachises of secondary inflorescences, panicle with fewer secondary inflorescences, and spikes with sparse pistillate flowers. Micromorphology of culms, cauline leaves, peduncles of secondary inflorescences, and achenes under SEM supports the recognition of this new species as well.  相似文献

卫矛科沟瓣属一新名称   总被引:1,自引:0,他引:1  
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。  相似文献

Micromorphological features of the seed surface of the Schisandraceae are reported for the first time. One hundred and seventeen seed samples from 92 populations, representing 24 species, seven varieties and one form of the Schisandraceae, were examined and photographed under scanning electron microscope (SEM). Micromorphological features of seed surfaces of the Schisandraceae are little affected by the habitats in which plants grow, and are quite constant within species, therefore they can be used as reliable diagnostic characters to distinguish species. The following taxonomic treatments are not supported by micromorphological features observed: ( 1 ) To reduce Schisandra wilsoniana A. C. Smith to S. henryi Clarke; (2) To reduce S. neglecta A. C. Smith, S. arisanensis Hayata, S. viridis A. C. Smith, S. sphenanthena Rehd. & Wils., S. gracilis A. C. Smith, S. micrantha A. C. Smith and S. lancifolia var. polycarpa Z. He to S. elongata ( Bl. ) Baill.; (3) To reduce S. henryi var. longipes (Merr. & Chun) A. C. Smith, S. tomentella A. C. Smith and S. pubescens var. pubinervis (Rehd. & Wils.)A. C. Smith to S. pubescens Hemsl. & Wils.; (4) To reduce S. rubriflora(Franch.)Rehd. & Wils., S. flaccidiramosa C. R. Sun, S. incarnata Stapf, S. sphaerandra Stapf, S. sphaerandra f. pallida A. C. Smith and S. glaucescens Diels to S. grandiflora ( Wall. ) Hook. f. & Thoms.; (5) To reduce Schisandra wilsoniana to S. bicolor Cheng; (6) To reduce S. lancifolia var. polycarpa to S. neglecta; (7) To raise S. henryi var. longipes to S. longipes(Merr. & Chun)R. M. K. Saunders; (8) To reduce Kadsura polysperma Yang to K. heteroclita(Roxb. )Craib. The relationship between Schisan-dra Michx. and Kadsura Kaempf. ex Juss. revealed by the micromorphological features of seed surface is very similar to that revealed by pollen morphology, namely these two genera might have originated from a common ancestor and then evolved along two different routes. However the probability of a more complicated relationship between the two genera than we have known hitherto can not be excluded. The general evolutionary level of Kadsura seems to be higher than that of Schisandra. Therefore, the viewpoint that Kadsura is more primitive than Schisandra is not supported.  相似文献
