中国大陆的一种植物新记录

1985年,我在参加由安徽省芜湖市科委、卫生局和九华山管理处联合组织的九华山植物资源调查中,采到一种兰科毛兰属植物,经鉴定系葡萄毛兰Eria reptans(Fr. et Sav.)Makino。本种只记载分布于日本和我国台湾岛,而在中国大陆是地理分布新记录。同时,毛兰属也是安徽省地理分布新记录的属。     

Typification of names in Cyperus section Arenarii (Cyperaceae)

The typification of names in the genus Cyperus was done as part of an ongoing study of the section Arenarii. The latest monograph on the genus by Kükenthal (1936), accepted eight species in the section Bobartia (= Arenarii ), and a number of lower level taxa, which are treated here either as distinct species or synonyms. The taxonomic treatment of the core species, C. conglomerates Rottb., turned out to be especially confusing, which is reflected in the past identifications of the material, and consequently, has created wrong interpretations on the distributions. C. jeminicus Rottb. has similarly caused a lot of confusion. Currently we recognize 26 species in the section, with two subspecies in C. conglomerate. Most names in the section have not earlier been typified. Here we designate lectotypes for 33 names, three epitypes, and one neotype. Cyperus sections Arenarii Kunth and Hymenolepides Nees are typified also.     

毛兰属植物化学成分及药理活性研究进展

毛兰属植物由于近年来同属于兰科的石斛属植物的过度采挖,而取代名贵中药石斛类作为药材应用。为了了解其化学成分及能否替代石斛应用,本文对毛兰属植物的化学成分及药理活性研究进展进行了综述。目前毛兰属植物研究所涉及的种类仅5种,从该属植物中分离出化学成分13种,包括菲类、9,10-二氢菲类及二聚体、联苄、甾体和脂肪族化合物等结构类型。药理研究表明,一些成分如毛兰素和毛兰菲在抗肿瘤和抗氧化等方面显示了较好的活性。开展毛兰属植物的研究,对发现新的药用活性成分及资源保护有重要意义。

Morphology and variability of pollen of the genus <Emphasis Type="Italic">Spiraea</Emphasis> L. (Rosaceae) in Siberia and the Far East

Pollen of 12 species of the genus Spirea L. growing in different regions of Siberia and the Far East was investigated. The ultrasculpture of pollen grains is described. On the basis of aperture morphology and exine sculpture, pollen grains are typified, with key indices given for their identification. The species of the Spiraria section are distinguished by large grains. Pollen grains of S. media and S. alpina considerably vary in size. The level of natural polymorphism of palynological indices has been established.     

Classification of uppermost Ordovician to Lower Devonian tubular and filamentous macerals from the Anglo-Welsh Basin

Dispersed tubes and filaments from the uppermost Ordovician, Silurian and Lower Devonian of the Anglo-Welsh Basin of Great Britain are described and classified using the artificial Anteturma system instituted for spores. The new Anteturma Trichomiformis is erected containing two new Turmae, Tubiformis and Filiformis. Within Tubiformis, the Infraturma Laevimurali, Endomurali and Extramurali are described, each containing a single genus with four, two and one species respectively. Within Filiformis, the Infraturma Ornatimurali is erected, based on a monospecific genus. Two assemblages of tubes and filaments are recognized. The older is found in uppermost Ordovician through to middle Silurian strata and is typified by a low diversity of smooth-walled tubes. The younger ranges from the middle Silurian at least to the Lower Devonian and is typified by various smooth-walled tubes, tubes with internal and external thickenings, and filaments. The majority of tubes and filaments are considered derived from the Nematophytales Lang.     

Pseudopollen in Eria Lindl. section Mycaranthes Rchb.f. (Orchidaceae)

BACKGROUND AND AIMS: Pseudopollen is a whitish, mealy material produced upon the labella of a number of orchid species as labellar hairs either become detached or fragment. Since individual hair cells are rich in protein and starch, it has long been speculated that pseudopollen functions as a reward for visiting insects. Although some 90 years have passed since Beck first described pseudopollen for a small number of Eria spp. currently assigned to section Mycaranthes Rchb.f., we still know little about the character of pseudopollen in this taxon. The use of SEM and histochemistry would re-address this deficit in our knowledge whereas comparison of pseudopollen in Eria (S.E. Asia), Maxillaria (tropical and sub-tropical America), Polystachya (largely tropical Africa and Madagascar) and Dendrobium unicum (Thailand and Laos) would perhaps help us to understand better how this feature may have arisen and evolved on a number of different continents. METHODS: Pseudopollen morphology is described using light microscopy and scanning electron microscopy. Hairs were tested for starch, lipid and protein using IKI, Sudan III and the xanthoproteic test, respectively. KEY RESULTS AND CONCLUSIONS: The labellar hairs of all eight representatives of section Mycaranthes examined are identical. They are unicellular, clavate with a narrow 'stalk' and contain both protein and starch but no detectable lipid droplets. The protein is distributed throughout the cytoplasm and the starch is confined to amyloplasts. The hairs become detached from the labellar surface and bear raised cuticular ridges and flaky deposits that are presumed to be wax. In that they are unicellular and appear to bear wax distally, the labellar hairs are significantly different from those observed for other orchid species. Comparative morphology indicates that they evolved independently in response to pollinator pressures similar to those experienced by other unrelated pseudopollen-forming orchids on other continents.     

Notes on the taxonomy and nomenclature of the algal classes Eustigmatophyceae and Tribophyceae (synonym Xanthophyceae)

The systematics of the Eustigmatophyceae are revised at the level of species, genus, family and order. All known species are included in the Eustigmatales, which is divided into four families: the Eustigmataceae Hibberd includes Eustigmatps Hibberd and Vischeria Pascher, each with three species; the Pseudocharaciopsidaceae includes only Pseudocharaciopsis Lee & Bold with two species; the Chlorobotryaceae includes only Chlorobotrys Bohlin with one species and the Monodopsidaceae includes Monodopsis Hibberd with one species and Nannochloropsis Hibberd with two species. Eustigmatophyta and Eustigmatophyceae are published as typified names for the division and the class, respectively, both based on Eustigmatos. Tribophyceae, based on Tribonema , is published as the typified name for the class previously called Xanthophyceae. Nannochloris coccoides Naumann is chosen as lectotype of the chlorophycean genus Nannochloris Naumann.     

On some crustose lichens with Wentepohlia from shaded overhangs in coastal Norway

Arthonia arthonioides (syn. nov. A. aspersa ) is reported as new to Scandinavia. Certain forms of it are superficially very similar to Lecanactis latebrarum (= Crocynia hueana ) which is typified and treated for the first time from Norway. Lecanactis abietina is reported to be a mainly coastal species in Norway - contrary to previous records. Lecanactis umbrina is transferred to the genus Schismatomma due to the discovery of apothecia and pycnidia typical of that genus.

Taxonomy of Asaemia with notes on Stilpnophyton (Compositae–Anthemideae)

Asaemia is a genus of one species with two subspecies from southern Africa. The nomenclature and systematic position of Asaemia and the related Stilpnophyton are discussed. Both genera are related to Athanasia. Asaemia minula (L. f.) Bremer and A. minuta ssp. inermis (Phillips) Bremer are new combinations. Stilpnophyton is typified by S. longifolium (Tfiunb.) Less.     

The Jakobid Flagellates: Structural Features of Jakoba, Reclinomonas and Histiona and Implications for the Early Diversification of Eukaryotes

ABSTRACT. Jakobid flagellates are small, free-living, bacterivorous heterotrophs, with similar morphology, asexual reproduction, and nucleocytoplasmic ultrastructural features at interphase and during cell division. Jakoba is typified by aloricate trophic cells, each containing a branched mitochondrion with prominent nucleoids and flattened cristae. Reclinomonas and Histiona are characterized by loricate trophic cells, each with an unbranched mitochondrion without prominent nucleoids or otherwise differentiated regions and bearing tubular cristae. An undescribed genus is typified by aloricate cells, each with an unbranched mitochondrion bearing discoidal cristae. I propose, on the basis of cytoskeletal architecture and other structural and developmental features, that jakobids are ancestral mitochondrial protists, sister taxa to the amitochondnal retortamonads and ancestral to diverse lineages of mitochondrial eukaryotes. Application of different classification paradigms produces different family-level taxonomies for jakobids.

A new species of the genus Torilis Adanson (Apiaceae)

JURY, S. L., 1987. A new species of the genus Torilis Adanson (Apiaceae). The name Torilis nodosa (L.) Gaertner has been shown to have been used to include two very distinct variants. Torilis nodosa is therefore typified, and the other variant described as a new species.     

Transfer of Kaempferia candida to Curcuma (Zingiberaceae) based on morphological and molecular data

Results of morphological studies supported by molecular analyses of chloroplast psbA‐trnH and partial petA‐psbJ DNA sequences indicate that Kaempferia candida cannot be retained in this genus. The species is here formally transferred to Curcuma and the name is typified. Notes on the species and colour plates are given.     

Typification of the Linnaean names of the genus Cardamine (Cruciferae)

Lectotypification of the following Linnaean names of the genus Cardamine L. (Cruciferae) is presented Cardamine asarifolia, C. graeca, C. petraea (|M= Cardaminopsis petraea), C. resedgolia (including designation of an epitype), C. trifolia and C. virginica. The lectotypes of the previously typified names of this genus and the protologues of these names are discussed. The probable typotype for the lectotype of C. azcana is identified and the need for the conservation of the type of C. chelidonia is noted.
