The genus Hypocenomyce (Lecanorales, Lecideaceae), with special emphasis on the Norwegian and Swedish species

Ten species are recognized in the genus Hypocenomyce. Their morphology, anatomy, chemistry, and ecology are discussed, a key is provided, and their distribution in Norway and Sweden is mapped. Hypocenomyce australis Timdal and H. foveata Timdal are described as new, and the combinations H. castaneocinerea (Räsänen) Timdal and H. praestabilis (Nyl.) Timdal are proposed. The genus can be divided into four species groups on the basis of apothecial and conidial characters, type of pigment in the epithecium and pyenidial wall, and chemical properties of the thallus. The delimitation of the genus in relation to Lecidea s. lat. is in need of further elucidation.     

关于中药巴戟天生药研究及《本草》重考

The aquatic triclads of the Grozet Islands (Platyhelminthes: Tricladida)

A new species of marine planarian, Obrimoposthia aparala sp. nov. , is described from the Crozet Islands and two other species are newly recorded for these islands, viz. 0. wandeli and Synsiphonium ernesti. The only known freshwater triclad from the Crozets, Dugesia seclusa , is redescribed from the type material. The morphology, ecology, and distribution of these four species is discussed.     

Morphology and taxonomy of the Puccinia species on corn and sorghum

Morphological characters of the sori and spore forms ofPuccinia polysora andP. purpurea are described and illustrated indicating the range of variation as determined from herbarium and field materials. Morphological variation inP. sorghi clones and inbred lines from these clones were studied earlier. The genes conditioning morphology apparently function independently of those conditioning pathogenicity. Race 13 ofP. purpurea was morphologically similar toP. sorghi and probably was not derived from the recombination of gametes ofP. purpurea as indicated in an earlier paper. Morphological distinctions between the 3 pathogens viz.P. sorghi, P. polysora andP. purpurea are wide. Taxonomically they are retained as valid species. A study of the complete life cycle of the latter 2 species and the genetic control of morphological characters, however, is essential to the final solution of the problem.     

Allium purpureoviride sp. nov. (Alliaceae) from east Anatolia,Turkey

Allium purpureoviride M. Koyuncu & ?. Genç (sect. Melanocrommyum) is described as a new species from east Anatolia, Turkey. The new species is closely related to A. rothii Zucc. from Israel and some characters of the new taxon show similarity with A. cyrilli Ten. and A. asclepiadeum Bornm. The morphological characters of the related taxa are discussed and the distribution of the taxa is mapped. The diploid chromosome number is 2n = 16.     

Notes on Ischnosiphon (Marantaceae)

Four new species are described, viz. Ischnosiphon bahiensis (Brazil), I. ursinus (French Guiana and Rio Negro Basin), I. crassispicus (vicinity of Manaus), and I. fusiformis (NE Peru). New data on ecology, morphology, or distribution are presented for I. inflatus Anderss., I. enigmaticus Anderss., I. centricifolius Anderss., I. gracilis (Rudge) Koern., I. helenae Anderss., I. macarenae Anderss., I. polyphyllus (P. & E.) Koern., and I. surumuensis Loes. The typification of I. arouma (Aubl.) Koern. is briefly discussed.

Jurinea tortumensis sp. nov. (Asteraceae) from northeast Anatolia,Turkey

A new species, Jurinea tortumensis A. Duran & B. Dogan (Asteraceae), is described and illustrated from Anatolia, Turkey. The species grows on serpentine stony places in the Tortum district (Erzurum Province) in northeast Anatolia. It is morphologically similar to J. consanguinea DC. The pollen characteristics and achene surface morphology of J. tortumensis and J. consanguinea are examined by SEM. Diagnostic morphological characters from closely similar taxa are discussed and arranged in a key. Ecology, conservation status and biogeography of the species are also presented. In addition, the geographical distributions of the new species and other related species are mapped.     

Taxonomic revision and phytogeographic studies in Euphorbia (Euphorbiaceae) in the Khorassan provinces of Iran

This study is focused on the genus Euphorbia L. in a part of northeast Iran, viz. the three Khorassan provinces. Since there are many taxa of Euphorbia in Iran which are used in different industries and have significant effects on human and non‐human life it is important to revise their taxonomy. With about 90 species, following Turkey with 91 species, Iran is the second richest country for Euphorbia in Asia. Of these, 30 species are distributed in the Khorassan provinces. This is the first comprehensive work on the genus in this region. According to ‘Flora Iranica’, there are 17 species of Euphorbia in northeast Iran, while according to our results, there are 30 species of Euphorbia in the Khorassan provinces alone. In addition to various new taxonomic and biogeographic results, a new species, viz. E. chamanbidensis, is described. Euphorbia chamanbidensis is closely related to E. aucheri, but seed micro‐morphological characters differentiate them. Two identification keys to the Euphorbia species of the studied area are provided, one based on macro‐morphological characters and another based on seed micro‐morphological characters. Phytogeographic analysis and distribution maps for all species are also presented.     

Scorzonera tuzgoluensis sp. nov. (Asteraceae), a new halophytic species from central Anatolia,Turkey

A new halophytic species, Scorzonera tuzgoluensis A. Duran, B. Do?an & S. Makbul sp. nov. (Asteraceae), is described and illustrated from Tuz Lake, central Anatolia, Turkey. The new species grows in salt marshes, is endemic (confined to central Anatolia) and closely related to Scorzonera parviflora Jacq. and S. elata Boiss. The diagnostic morphological characters of these similar taxa are discussed. The ecology, biogeography and conservation status of the new species are also presented. The geographic distribution of the new species and related species is mapped.     

A revision of the Paeonia suffruticosa complex (Paeoniaceae)

The taxonomical concept of the Paeonia suffruticosa complex i.e. Sect. Moutan Subsect. Vaginatae, has changed greatly since 1990. Six species and four subspecies have been described as new and two subspecies raised to specific level. Five species and two subspecies are recognized in the present revision, viz. P. suffruticosa subsp. suffruticosa and subsp. yinpingmudan, P. jishanensis, P. qiui, P. ostii, P. rockii subsp. rockii and subsp. taibaishanica. P. yananensis, P. ridleyi, P. spontanea, P. moutan subsp. atava, P. suffruticosa subsp. atava, P. rockii subsp. linyanshanii and P. ostii var. lishizhenii are treated as synonyms. P. papaveracea and P. baokangensis are proposed to be interspecific hybrids. A key to the recognized species and subspecies is provided. Biological features of the species are described and their distributions are mapped. The relationships between species are inferred and the origins of commonly cultivated tree peonies ( P. suffruticosa and P. ostii ) are discussed.     

A revision of the lygaeid genus Pseudopachybrachius (Hemiptera)

Abstract. The rhyparochromine lygaeid genus Pseudopachybrachius is revised. Four species are recognized in the perplexing vinctus-gvoup (viz capicola, reductus, vinctus and guttus) based on the genitalia details and external features. One new species, P.concepcioni sp.nov., is described from the West Indies and South America. New distributional records are given for all species. Pamera dubia Reuter 1882 is synonymized with Pseudopachybrachius reductus (Walker, 1872) and a neotype is designated for Rhyparochromus inconspicuus Dallas, 1852. A key and diagnostic characters of seven species are given. Phylogenetic and zoogeographic relationships are discussed. Illustrations of the genitalia, a cladogram and diagnostic external features are included.
