A worldwide phylogenetic classification of the Poaceae (Gramineae) III: An update

We present an updated worldwide phylogenetic classification of Poaceae with 11 783 species in 12 subfamilies, 7 supertribes, 54 tribes, 5 super subtribes, 109 subtribes, and 789 accepted genera. The subfamilies (in descending order based on the number of species) are Pooideae with 4126 species in 219 genera, 15 tribes, and 34 subtribes; Panicoideae with 3325 species in 242 genera, 14 tribes, and 24 subtribes; Bambusoideae with 1698 species in 136 genera, 3 tribes, and 19 subtribes; Chloridoideae with 1603 species in 121 genera, 5 tribes, and 30 subtribes; Aristidoideae with 367 species in three generaand one tribe; Danthonioideae with 292 species in 19 generaand 1 tribe; Micrairoideae with 192 species in nine generaand three tribes; Oryzoideae with 117 species in 19 genera, 4 tribes, and 2 subtribes; Arundinoideae with 36 species in 14 genera and 3 tribes; Pharoideae with 12 species in three generaand one tribe; Puelioideae with 11 species in two generaand two tribes; and the Anomochlooideae with four species in two generaand two tribes. Two new tribes and 22 new or resurrected subtribes are recognized. Forty-five new (28) and resurrected (17) genera are accepted, and 24 previously accepted genera are placed in synonymy. We also provide an updated list of all accepted genera including common synonyms, genus authors, number of species in each accepted genus, and subfamily affiliation. We propose Locajonoa, a new name and rank with a new combination, L. coerulescens. The following seven new combinations are made in Lorenzochloa: L. bomanii, L. henrardiana, L. mucronata, L. obtusa, L. orurensis, L. rigidiseta, and L. venusta.     

小腹茧蜂亚科的雄外生殖器及族级单元系统发育的研究

对分布在东洋区和古北区的小腹茧蜂亚科 (膜翅目: 茧蜂科)21个属的67个种及外群折脉茧蜂属 (膜翅目: 茧蜂科) 2个种的雄外生殖器的5个性状进行了比较研究。在形态学研究的基础上,通过选用头部、胸部和腹部(包括雌雄外生殖器的性状) 等34个性状,运用支序分析的方法探讨了分布在东洋区和古北区的小腹茧蜂亚科21个属以及它们所属的族间的系统发育关系,并对Mason (1981) 的分类系统进行了重新评价。雄外生殖器和支序分析基本上证实并恢复了由Mason (1981) 确定的2个主要分支,即绒茧蜂族Apantelini+小腹茧蜂族Microgastrini和拱茧蜂族Fornicini+盘绒茧蜂族Cotesiini+侧沟茧蜂族MicroplitinI。绒茧蜂族Apantelini、拱茧蜂族Fornicini和侧沟茧蜂族Microplitini为单系群也被支持,但小腹茧蜂族Microgastrini和盘绒茧蜂族Cotesiini是否为单系群尚难于在树形图中体现,而且族内各属间的分支关系有变动。因此,尽管Mason的族级分类单元有一些欠缺,但仍是可信、实用的,不同意Walker等 (1990) 认为不应再使用Mason分族系统的观点。     

A comprehensive generic-level phylogeny of the sunflower family: Implications for the systematics of Chinese Asteraceae

The sunflower family (Asteraceae) is the largest and the most diverse flowering plant family, comprising 24 000–30 000 species and 1600–1700 genera. In China, Asteraceae are also the largest family, with approximately 2336 indigenous species in 248 genera. In the past two decades, molecular phylogenetic analyses has contributed greatly to our understanding of the systematics of Asteraceae. Nevertheless, the large-scale analyses and knowledge about the relationships of Chinese Asteraceae at the generic level as a whole are far from complete due to difficulties in sampling. In this study, we presented a three-marker (rbcL, ndhF, and matK) phylogeny of Asteraceae, including 506 genera (i.e., approximately one-third of Asteraceae genera). The study sampled 200 Chinese genera (i.e., approximately 80% of Chinese Asteraceae genera). The backbones of the new phylogeny were largely congruent with earlier studies, with 13 subfamilies and 45 tribes recognized. Chinese Asteraceae were distributed in 7 subfamilies (Mutisioideae, Wunderlichioideae, Carduoideae, Pertyoideae, Gymnarrhenoideae, Cichorioideae, and Asteroideae) and 22 tribes (Mutiseae, Hyalideae, Cardueae, Pertyeae, Gymnarrheneae, Vernonieae, Cichorieae, Doroniceae, Senecioneae, Astereae, Anthemideae, Gnaphalieae, Calenduleae, Inuleae, Athroismeae, Helenieae, Coreopsideae, Neurolaeneae, Tageteae, Millieae, Eupatorieae, and Heliantheae). Chinese Asteraceae lacked 6 basal subfamilies and 23 tribes. Several previously ambiguous relationships were clarified. Our analyses also resolved some unplaced genera within Chinese Asteraceae. Finally, our phylogenetic tree was used to revise the classification for all genera of Chinese Asteraceae. In total, 255 genera, 22 tribes, and 7 subfamilies in China are recognized.

Midges of the subfamily Tanypodinae (Diptera,Chironomidae) of Russia: Tribes Coelotanypodini Kieffer, 1913 and Tanypodini Meigen, 1803

It is established that in the territory of Russia the subfamily Tanypodinae (Diptera, Chironomidae) includes 80 species belonging to 10 subgenera of 8 genera and 5 tribes; 4 species are recorded for the first time in the Palaearctic Region, and 16 species, in Russia. In the present study, larvae, pupae, and male adults from different areas of Russia, belonging to 9 species of 2 subgenera, 2 genera, and 2 tribes, are examined. Keys to larvae, pupae, and male adults of these species is provided.     

Phylogeny and classification of Leptophlebiidae (Ephemeroptera) with an emphasis on Neotropical fauna

Mayflies from the family Leptophlebiidae are cosmopolitan and highly diverse morphologically; they are also the largest family in numbers of genera and the second in number of species in the order Ephemeroptera. In spite of their broad diversity and the efforts employed to understand the evolution of this group, the internal classification of Leptophlebiidae remains controversial at all levels. More recently, important changes have been incorporated into the systematics of the family, increasing the number of subfamilies (from two to six) and recognizing several tribes. We present a phylogeny of the family based on 153 taxa (53 genera) and two molecular markers, representing 1655 bp, and verify the taxonomic status of the subfamilies, tribes and complexes. Based on these results, the number of subfamilies has been increased from six to eight and one new tribes and two new subtribes have been added. In addition, new ranks are proposed and the concept of Atalophlebiinae revised, including genera with distributions in the Australasian and Neotropical regions.     

Phenetic and cladistic relationships among tenebrionid beetles (Coleoptera)

Abstract. The higher classification of Tenebrionidae is analysed using numerical phenetic, numerical cladistic and traditional Hennigian methods. In all, eighty characters are examined for about 335 taxa; definitive analyses are made on combinations of eighteen to seventy characters for thirty-three OTUs. At lower levels of relationship (genera and closely related tribes) phenetic and cladistic classifications are shown to be congruent, but at higher levels (tribes and subfamilies) there is marked discordance with phenetic results being more stable. A consensus classification is more similar to the Hennigian cladogram than is any single computer generated cladogram. Two main tribal groups – the Lagrioid and Tenebrionoid groups – are suggested which differ in defensive glands, female anatomy, wing and mouthpart morphology, larval characters and other features. The Tenebrionoid group consists of three main subdivisions – the tenebrionine, coelometopine and diaperine lineages. Changes in classificatory position are recommended for eighty-seven genera and tribes (listed in Appendix E) and implied for numerous others.     

Characters of Leaf Epidermis and Their Systematic Significance in Menispermaceae

The epidermal characters of mature leaves of 29 genera, 50 species and 3 varieties (totally 56 samples) representing all the 5 tribes in the family Menispermaceae were examined under the light microscope. The main conclusions are as follows: (1) The shape of the epidermal cells is polygonal or irregular, and the anticlinal walls are straight or waved in the family. In some genera a special arrangement of epidermal cells is named as “rosette-cell arrangement" for the first time. The lower epidermal cells were found to have a papilla in Stephania, Diploclisia and Legnephora . (2) In some genera, the anticlinal walls are oblique, rather than perpendicular, to the surface. (3) The stomatal apparatuses, generally restricted to the lower surface of the leaves, were assigned to anomocytic, staurocytic, cyclocytic, anisocytic and actinocytic types, and their distribution on the epidermis may be of diffuse pattern or island congregating pattern. (4) The cells of both upper and lower epidermis in the tribe Pachygoneae and Fibraureae are generally polygonal with straight or arched anticlinal walls, and the stomatal apparatuses are usually staurocytic and actinocytic. The cyclocytic stomatal apparatus was found only in two genera of the tribe Pachygoneae. By contrast, the epidermal cells of the tribes Anomospermeae, Tinosporeae and Menispermeae are generally irregular with waved anticlinal walls, and the stomatal apparatuses are predominantly anomocytic. These correlated characters are of much significance in delimiting tribes within the Menispermaceae, and also provide evidence for studies on systematic relationships of several genera.     

The Geographical Distribution of the Subfamily Cyrtandroideae Endl. Emend. Burtt (Gesneriaceae)

Based on Burtts classification and relevant references, the geographical distribution of the subfamily Cyrtandroideae Endl. emend. Burtt is outlined, distribution maps of 79 genera are provided, and some evolutionary trends of the taxa are inferred. The main points may be summarized as follows:1. The centre of distribution The Cyrtandroideae consists of four tribes, 79 genera and about 1770 species, widely distributed in tropical and subtropical regions of the Old World, ranging from Guinea eastwards to Nukuhiva Islands and from Western Bulgaria southwards to Southern Natal, with only one species disjunctly occurring in tropical America. According to Takhtajans (1978) regionalization of the world flora, and referring to Goods (1974) and Wus (1979) scheme, the distribution patterns of Cyrtandroideae may be generalized as: (1) Pantropics, with 3 genera; (2) Palaeotropics, with 47 genera; and (3) North Temperate, with 27 genera. Tropical Asia (Indo Malaysia) is the centre of variation and diversity of the Cyrtandroideae, where the most primitive taxa, with the chromosome number of n=8 or n=9, and all of the four tribes exist, and where more genera(50) and species (1200 odd) are found than elsewhere. Among the four tribes of the Cyrtandroideae, only two tribes are distributed west of India. Three European genera with six species, confined to the Mediterranean, belong to one tribe, Didymocarpeae. Of 10 African and Madagascar genera, 9(7 endemic) belong to Trib. Didymocarpeae, 1 to Trib. Klugieae, and a11 of 168 African and Mada gascar species are not outside both of these regions. 2. Disjunct distribution and dispersal In Trib. Klugieae, two species of Epithema are found disjunctly in west Africa, and one species of Rhynchoglossum, R. azureum, is disjunct in tropical America, from southern Mexico to northern Peru. Their closely allied species and neighbouring genera are in tropical Asia. Rhynchoglossun azureum has a close relationship with R. notonianum, which is located in India and Sri Lanka, so it is hypothesized that Rhyncho glossum existed in north Africa, where there were tropical rain forests similar to those in Malaysia during the Tertiary. The author noticed that seeds of R. obliquum from tropical areas of southern Yunnan can still germinate after seven months at normal temperature. Most seeds of this genus are not only long lived but very tiny (0.3～0.4 mm long), and can be dispersed by wind or birds (epizoochore through the agency of mucus). One or two species of Rhipsalis in Cactaceae was carried by birds from south America to Madagascar, the Mascarene Islands and Sri Lanka at an early period. This example indicates the possibility of this means of distribution. More than 200 species from the volcanic islands of the Polynesian region, including the Hawaiian Islands,all belonging to Cyrtandra, were obviously spread by birds from tropical Asia during an earllier period. The distribution of two species of Boea and one species of Cyrtandra in northeast Queensland shows that some early taxa of the genera entered Yorke Peninsua from New Guinea when the sea level was lower during the Quaternary glaciations The modern vicarious distribution patterns of the two subfamilies indicate that the main taxa of the family were produced during the course of the continental drift and the climatic and environmental changes. According to the principle of common origin, the ancestor of Gesneriaceae appeared most probably not later than the late Cretaceous, and might be traced back to the Mid Cretaceous. 3. Some problems about evolutionary tendencies In general, the actinomorphic corolla precedes the bilabiate one, and the flower with stamens all fertile precedes those with 1 or 3 staminodes (Ivanina, 1965; Wang, 1989、 1992). In some diandrous genera of Cyrtandroideae, 4 or 5 fertile stamens may occur exceptionally, and are associated with a more or less regular corolla. The exceptional appearances may possibly be atavistic, not representing the main evolutionary tendencies. In the genus Aeschynanthus, pollen grains of Sect. Haplotrichum and Sect. Diplotrichum, whose corollas usually have indistinct bilabiate limbs, are comparatively small, but large in sections Microtrichium, Xanthanthos and Aeschynanthus, whose corollas have distinct bilabiate limbs. 4. The relationships of the four tribes he tribes Cyrtandreae, Trichosporeae and Didymocarpeae are closely related (Kvist and Pedersen, 1986). Some terrestrial plants of Trib. Trichosporeae (e.g.Anna and Lysionotus Sect. Didymocarpoides), in which the seeds have subulate appendages at their ends, may represent the intermediate links between tribes Didymocarpeae and Trichosporea.Boeica and Hexatheca form natural links between the tribes Cyrtandreae and Didymocarpeae. The tribes Didymocarpeae and Klugieae probably originated from a common ancestor at an early stage in the evolution of the family.

Taxonomic significance of pollen types in the Guyana Highland-centred composite genera of Mutisioideae (Asteraceae)

The Guyana Highland-centred genera, or Stenopadus group, are a complex of species that belong to the tribes Mutisieae and Stifftieae of Asteraceae. The pollen morphologies of 29 species, from 12 of 13 genera of this complex, are described and illustrated using light and scanning electron microscopy. The exine sculpture and structure are highly significant. Four exine types, previously characterized, were distinguished: Gongylolepis , Wunderlichia , Mutisia , and Stenopadus . The characterization of the Stenopadus exine type is enlarged here. These exine types led to the recognition of four well-defined pollen types, whereas the spine length and exine thickness characterized six subtypes. Pollen types circumscribe genera or groups of genera, and some subtypes distinguish species. The pollen morphology within the complex is discussed in relation to the rest of Mutisioideae and other palynologically allied tribes of Cichorioideae. There is little correlation between pollen types and tribes; only the Stenopadus exine type is exclusive to the Stifftieae tribe. The remaining types are shared by the two tribes of the complex. Pollen morphology supports the hypothesis that this group of genera is close to the Gochnatia complex and the Cardueae tribe.  © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society , 2008, 156 , 327–340.

虎尾草亚科系统发育关系的初步研究

运用广义形态学性状对虎尾草亚科（Chloridoideae）进行系统发育分析。内类群包括虎尾草亚科52属的69种植物,代表虎尾草亚科的主要类群;芦竹亚科（Arundinoideae）扁芒草族（Danthonieae）的Centropodia和Danthonia被选作外类群。分支分析表明,虎尾草亚科是一个单系类群。其严格一致树包括A、B、C、D、E5个分支。两个大族画眉草族（Eragrostideae）和虎尾草族（Chlorideae）代表虎尾草亚科内部类群分化的两个方向,分开处理较合理。细穗草族（Leptureae）放到虎尾草族中较合理。冠芒草族（Pappophoreae）是虎尾草亚科的基部类群,与画眉草族近缘。我们的研究支持虎尾草亚科从旧世界向新世界扩散的地理分布假说,并提供了虎尾草亚科属上类群的系统发育关系的框架。     

Molecular phylogeny of Palaearctic genera of Gomphocerinae grasshoppers (Orthoptera, Acrididae)

Abstract.  Molecular phylogenetic methods were used to examine morphologically based hypotheses concerning the taxonomic structure and relationships of the grasshopper subfamily Gomphocerinae. Two mitochondrial gene (cytochrome b and cytochrome oxidase subunit I) sequences were determined for twenty-five species representing eleven Palaearctic genera. The studied Gomphocerinae species constituted a monophyletic group; furthermore, the earlier division of Gomphocerinae into tribes was supported, with each tribe monophyletic. There was no support for various systems uniting Stenobothrini and Gomphocerini into one tribe. Two separate clusters were discerned in Gomphocerini and two tribes were distinguished – Gomphocerini (genera Aeropus , Stauroderus , Chorthippus ) and Stenobothrini (genera Omocestus , Stenobothrus ).     

Vascular transfer cells in leaves of Leguminosae-Papilionoideae

A survey of A-type transfer cells in leaves of 118 species representing 87 genera and 3 5 tribes of Leguminosae-Papilionoideae suggests that their presence or absence is taxonomically predictable both at tribal level and in terms of major series of tribes. Members of 'pulvinate' (tropical) tribes generally lack transfer cells, while 'epulvinate' (temperate) forms commonly possess them.     

THE SYSTEMATIC SIGNIFICANCE OF SEED MORPHOLOGY IN THE NEOTROPICAL CAPSULAR-FRUITED MELASTOMATACEAE

Seed shape has traditionally been used as a tribal character in the capsular-fruited Melastomataceae. The seed morphology of the five neotropical tribes—Microlicieae, Tibouchineae, Rhexieae, Merianieae, and Bertolonieae—was studied with scanning electron and light microscopes. On the basis of seed morphology, five seed types are recognized: microlicioid, tibouchinoid, rhexioid, merianioid, and bertolonioid. Each of these types is illustrated and discussed, with some observations on the range of variation found. The genera of these five neotropical tribes were surveyed for seed morphology, and the results are presented here, together with a discussion of their systematic significance. On the whole, seed morphology confirms the existence of five tribes among the neotropical capsular-fruited Melastomataceae and provides interesting evidence for generic relationships; however, it also calls into doubt the taxonomic disposition of certain genera and the delimitation of these five tribes. The seeds of most genera fit into one of these five basic types, but there are some which do not; these exceptions are discussed in terms of their seed morphology and possible relationships.
