Zenkerella perplexa sp. nov. from the Uluguru Mts in Tanzania is described and illustrated. Differences between this species and Z. egregia are pointed out.     

Neue Gattungen der FamilieLecideaceae s. lat. (Lichenes)

Six new genera are designated for the predominantly foliicolous specíes with hyaline, septate ascospores originally included in the artificial generaBacidia, Catillaria andLopadium. These areFellhanera gen. n. which, on the basis of ascus structure, belongs to the familyPilocarpaceae and includes 19 species, as well asBadimia gen. n. (6 species),Barubria gen. n. (1 species),Loflammia gen. n. (3 species),Calopadia gen. n. (6 species) andLogilvia gen. n. (1 species) which with the previously described generaLasioloma R. Sant. andTapellaria Müll. Arg. em.R. Sant. are classified in the familyEctolechiaceae as they are related toSporopodium Mont. The campylidia, special reproductive organs of the lichens concerned, are present in all members of the family. They are considered to be phylogenetically derived from apothecia. The conidia they produce vary in shape and structure and can be divided into different types, each of which is characteristic of a particular genus. The necessary new combinations are introduced in an appendix.     

Ecuadorian Brownea and Browneopsis (Leguminosae-Caesalpinioideae): Taxonomy, palynology, and morphology

The neotropical genera Brownea and Browneopsis are understorey trees and shrubs of lowland rain forest comprising twelve and six species, respectively. Four species of Brownea and three of Browneopsis occur in Ecuador. Keys to the genera and species in Ecuador are provided, and Brownea coccinea, B. grandiceps, B. macrophylla, B. multijuga, Browneopsis disepala, B. ucayalina , and B. macrofoliolata are described, the last-named as a new species. Additionally, the intergeneric relationships, and the morphological and the palynological variation in the genera are surveyed.     

Bacidina genus novum familiaeLecideaceae s. lat. (Ascomycetes lichenisati)

The following eleven species currently classified in the generaBacidia s. lat. andCatillaria s. lat. are transferred to the new genusBacidina Vězda gen. n. (Lecideaceae s. lat.):Bacidina apiahica (Müll. Arg.) comb. n.,B. chloroticula (Nyl.)Vězda etPoelt comb. n.,B. egenula (Nyl.) comb. n.,B. inundata (Fr.) comb. n.,B. mirabilis (Vězda) comb. n.,B. neglecta (Vězda) comb.n.,B. pallidocarnea (Müll. Arg.) comb. n.,B. phacodes (Koerb.) comb.n.,B. scutellifera (Vězda) comb.n.,B. vasakii (Vězda) comb.n., andB. ziamensis (Vězda) comb.n.     

Infraspecific variation in Cerastium alpinum s. lat. (Caryophyllaceae) in Central Norway

Within Cerastium alpinum s. lat., several taxa have been circumscribed. Three infraspecific taxa are currently recognized in Nordic literature, but the opinions have varied about their taxonomic levels and relations to each other. Populations of these three taxa — alpinum, glabratum and lanatum — were investigated in Central Norway to elucidate taxonomic relationships on a regional scale. Morphometric analyses (PCA ordination) based on two data sets; one with 61 characters, and one without the 35 indumentum characters, gave different results. The former partly support the use of a higher rank for glabratum , but this analysis may put too much weight on indumentum characters. The reduced data set gave a more continuous transition between the three taxa, with no special status for glabratum. Crossing experiments between the taxa indicated full cross compatibility as far as relative seed set was concerned. Finally, vegetation analysis (DCA ordination) indicated that the three taxa have somewhat different ecological demands. This suggests that they, in spite of hybridization abilities, normally are maintained as separate entities due to habitat differences. A delimitation of three infraspecific taxa at the same level within C. alpinum s. lat. is thus supported by this study. Whether these taxa should be treated as subspecies or varieties strongly depends upon the definitions of these categories. Viewed in a wide geographical context, however, the arguments for subspecific rank are strengthened.     

Environmental constraints on microevolution in Prasiola stipitata s. lat. (Prasiolales: Chlorophyta)

Three cultured strains of Prasiola stripitata were established from populations on shores of NW England (Hilbre), N Norway (Vardö) and SW Finland (Ören). Experiments were carried out on the effects of seawater salinity (6, 34, 68, 102%o) on these strains. All isolates showed significant differences in plantlet density in response to salinity, and density maxima at 34%o. The Ören culture density was least reduced at 6%.
Growth of these isolates was also significantly affected by salinity and their patterns of response also differed significantly. The Hilbre strain proved to be the most vigorous in 68 and 102%o. The Ören strain performed best in 6 and 34%o and grew very poorly in 102%o. The responses of the Vardö isolate proved to be somewhat intermediate in character. Microevolutionary divergence can therefore occur in this taxon but the constraints imposed by the harsh conditions at high shore levels in all localities ensure that differences in salt tolerance between ecotypes will be small.     

Allozyme differentiation between lowland and alpine populations of Pseudorchis albida s.lat. (Orchidaceae) in Sweden

Two taxa are usually recognized in Scandinavian Pseudorchis albida s.1. (Orchidaceae), the lowland to subalpine P. albida s.s., and the alpine P. straminea . We used allozymes to study the genetical differentiation within and among populations and taxa. Four populations of P. albida s.s. and two populations of P. straminea , all from Sweden, were included in the study. Eighteen loci of thirteen different enzyme systems were analyzed. Five loci were variable within, or between, the taxa. The taxa had different alleles at one of the five variable loci, whereas there was overlap at four loci. In all, 22 different alleles were found. Two of these alleles were confined to P. albida s.s., while four alleles were confined to P. straminea . In P. albida s.s., one locus out of 15 (6.7 %) was polymorphic. In P. straminea , three loci out of 18 (16.7 %) were polymorphic. In both taxa, the average number of alleles per polymorphic locus was 2.0 (each polymorphic locus had two alleles). Nei's genetic identity was 0.81 between taxa, and about 1 among populations of P. albida s.s., while the identity between the two populations of P. straminea was 0.98. Although the differentiation is small, present-day distributions of taxa suggest that the divergence probably started before the Weichselian glaciation. The low within-taxon and within-population variation in Scandinavia may be due to ancient founder events. The association of P. albida s.s. with anthropogenic hay-meadows and open woodland and the association of P. straminea with open mountain habitats suggest that taxa may have immigrated into Scandinavia at different times.     

Taxonomy and distribution of the genus Quillaja Molina (Quillajaceae)

The taxonomy and distribution of the genus Quillaja (Quillajaceae) is examined and two species, Q. brasiliensis and Q. saponaria, are recognised and keyed out. Quillaja bra‐ siliensis is distributed in southern Brazil, northern Uruguay, northeastern Argentina and eastern Paraguay. The presence of Q. brasiliensis in Peru, indicated in some sources, is not confirmed with herbarium specimens. Quillaja saponaria is distributed in central Chile, besides one doubtful collection from Andean Bolivia. The mention of its presence in Peru is likewise unjustified. A distribution map of the species is provided and two names are lectotypified here. Se examina la taxonomía y distribución del género Quillaja (Quillajaceae), donde dos especies, Q. brasiliensis y Q. saponaria, se reconocen y diferencian mediante una clave. Quillaja brasiliensis se distribuye en el sur de Brasil, norte de Uruguay, noreste de Argentina y este de Paraguay. La presencia de Q. brasiliensis en Perú, indicada en algunas fuentes, no se ve respaldada por ejemplares de herbario. Quillaja saponaria se distrbuye en Chile central, más una colección dudosa proveniente de los Andes de Bolivia. La mención de Q. saponaria para Perú tampoco se justifica. Se presenta un mapa de distribución de las especies y se lectotipifican dos nombres. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)     

Taxonomy and distribution of deepsea herring (Bathyclupeidae) in oceans

This paper provides an overview of the family Bathyclupeidae of the world fauna; the geographic and bathymetric distribution of species is updated. It is concluded that the family includes nine species that are grouped into two genera—Bathyclupea Alcock and Neobathyclupea gen. nov. The new genus differs from the type one by the development of black pigment in the orobranchial cavity, smooth ventral branch of preoperculum, developed last pair of pleural ribs, and the number of rays in the vertical fins.     

Taxonomy and distribution of Chaptalia dentata and C. Albicans (Asteraceae: Mutisieae)

Chaptalia dentata (L.) Cass. andC. albicans (Sw.) Vent. ex Steudel incorrectly have been recognized as conspecific in recent treatments. Although they are vegetatively similar, they differ in features of the flowers and fruits—especially the mature achenes. Both species occur in the Bahamas and the Greater Antilles of the West Indies:Chaptalia dentata is endemic to that area, absent only from Jamaica;C. albicans is more widespread, as it occurs in Jamaica as well as in scattered localities on the American mainland—southern Florida, various localities in Belize, Honduras, and Guatemala, and the Mexican states of Veracruz, San Luis Potosí, Chiapas, and Yucatán.     

Reclassification of Cupes Fabricius (s.lat.), with descriptions of new genera and species (Cupedidae: Coleoptera)

ABSTRACT.
The classification of Cupes Fabricius (s.lat.) is discussed. Details of previously proposed species groupings are expanded and supported by characters of the male genitalia. In addition to Cupes (s.s.) five new genera (Tenomerga, Distocupes, Adinolepis, Ascioplaga and Rhipsideigma) are established and the total number of species is raised to twenty-four of which seven are new: Tenotnerga trabecula, T.kapnodes, T.favella, Adinolepis scalena, Ascioplaga mimeta, A.sciasma and Rhipsideigma adjuncta. The known distribution is extended and now includes the NE of North America, E and S Africa including Madagascar, E Asia, E Australia, Borneo, New Guinea, New Caledonia and the Hawaiian Islands. Types of most species have been examined and figured.     

Bauhinia leucantha sp. nov. (Leguminosae-Caesalpinioideae) and notes on B. ellenbeckii

Bauhinia leucantha sp. nov. is described from central Somalia. The new species is related particularly to B. ellenbeckii in Ethiopia and Somalia, B. teitensis in Kenya, and B. natalensis in eastern South Africa. B. somalensis is reduced to a synonym of B. ellenbeckii and the distribution of this species is shown to extend to northern Somalia.     

基于核糖体DNA内转录间隔区ITS序列的广义蓼属及近缘属分子系统学研究

通过对广义蓼属及近缘属共32个代表种内转录间隔区ITS序列的分子系统学分析,尝试研究备受争议的广义蓼属及近缘属的物种族、属、组级的划分问题,结果显示,广义蓼属在系统发育树上并不能形成一个单系类群,这些物种共聚为3大支,分别对应春蓼族、蓼族及荞麦族,其中荞麦属与翅果蓼属形成了一支独立于春蓼族及蓼族之外的类群。在春蓼族中,冰岛蓼属与分叉蓼组形成一个单系类群。

The varieties of Bauhinia pottsii G. Don in Thailand (Leguminosae-Caesalpinioideae)

 Bauhinia pottsii G. Don, B. subsessilis Craib, B. velutina (Wall. ex Benth.) Baker, B. mollissima (Wall.) Prain, and B. decipiens Craib were recently recognized as five varieties of Bauhinia pottsii G. Don. They grow naturally in southern Myanmar, Thailand, Indochina and the Malay Peninsula. Bauhinia pottsii var. decipiens (Craib) K. Larsen & S. S. Larsen is endemic to Thailand and known only from the type collection, so it was omitted from this study. Quantitative and qualitative morphological characters were examined in 200 specimens using multivariate and univariate analyses to determine the taxonomic relationship among the four. Some variation in qualitative characters was found between the varieties which separated them as previously defined in Flora of Thailand. Forty-three quantitative characters were subjected to cluster analysis to allow an objective classification into groups. The groups were subsequently evaluated by a canonical discriminant analysis. It was found that these characters collectively support the four varieties as defined by qualitative characters. However, the close relationship of varieties mollissima (Wall. ex Prain) K. Larsen & S. S. Larsen and velutina (Wall. ex Benth.) K. Larsen & S. S. Larsen is observed. The linear discriminant function has an overall rate of 98.5% correct classification and is useful for variety classification. Among quantitative characters, petal-claw length and ovarystalk length together with some qualitative characters are useful for key construction to separate the four varieties.
