Gyrosigma tenuissimum (W.Sm.) J.W.Griffith & Henfr. was examined in the original material and an emended description is presented. Its protologue contains an error of taxonomic significance: in the type material, the valve and raphe sternum do not show the considerable flexure described and illustrated in Smith (1853). A comparison with Gyrosigma coelophilum N. Okamoto & Nagumo revealed that the latter, although similar in several characters, differs sufficiently in others to warrant separate specific status. Descriptions of two new taxa are given: Gyrosigma tenuissimum var. gundulae var. nov. and Gyrosigma baculum sp. nov. Both show very fine longitudinal striae at or beyond the limit of ordinary light microscopy and are practically non-sigmoid

Problems of infrageneric classification in Pedicularis L. (Scrophulariaceae), and the phytogeography of the genus in the Flora of Bhutan area, are discussed. Six new species and one new variety of Pedicularis L. are described. Pedicularis garckeana Prain ex Maxim. is separated from P. ser. Robustae Prain as the new, monospecific series Garckeanae R. R. Mill (Sikkim and adjacent Xizang). Six of these new taxa are endemic to Bhutan (P. dhurensis R. R. Mill sp. nov., P. longipedicellata P. C. Tsoong var. lanocalyx R. R. Mill var. nov., P. melalimne R. R. Mill sp. nov., P. microloba R. R. Mill sp. nov., P. sanguilimbata R. R. Mill sp. nov. and P. woodii R. R. Mill sp. nov.) and one (P. yarilaica R. R. Mill sp. nov.) occurs in N Bhutan and S Xizang. The type material of Phtheirospermum auratum Bonati (=Pedicularis aurata (Bonati) H. L. Li) is shown to be a mixed gathering; the name is lectotypified and an emended description of P. aurata given. Several other names are lectotypified. Three sectional names originally proposed by Yamazaki (each ‘based’ on invalid ‘names’ of groups earlier recognized as subgreges by Tsoong) are validated as P. sect. Asthenocaulus [P. C. Tsoong ex] R. R. Mill, P. sect. Nothosigmantha T. Yamaz. ex R. R. Mill, and P. sect. Rhizophyllastrum T. Yamaz. ex R. R. Mill, while a fourth invalid section (‘P. sect. Brachystachys (P. C. Tsoong) T. Yamaz.’) is here recognized and described as P. sect. Brevispica R. R. Mill, sect. nov. Pedicularis sect. Cryptorhynchus T. Yamaz. and P. sect. Elephanticeps T. Yamaz. are provided with emended descriptions. The nomenclature of P. pennelliana P. C. Tsoong and related taxa of the P. gracilis Wall. ex Benth. complex is discussed.

AbstractThe metabolic diseases gout and calciumpyrophosphate deposition (CPPD) (formerly: chondrocalcinosis/pseudogout) are crystal arthropathies which are caused by crystals in synovial fluid and in the case of gout also in periarticular structures. Today, in particular gout is considered as an auto-inflammatory process since phagocytosis of monosodium urate crystals by monocytes/macrophages results in the activation of the innate immune system by activation of the NRLP3-Inflammasome and consecutive secretion of the key cytokine interleukin-1ß and other pro-inflammatory cytokines. The prevalence of both crystal arthropathies rises with increasing age of patients. Most often they present clinically as an acute monarthritis of different locations. Beside typical clinical presentation, performance of ultrasonography, conventional X-Ray of joints and under special circumstances dual-energy-computer tomography could be also helpful diagnostic tools. There are EULAR guidelines describing the diagnostic algorithm for making right diagnosis. The arthrocentesis with microscopic detection of crystals is established diagnostic gold standard. Whereas crystals of monosodium urate could be very clearly be seen as relatively large intra- and extracellular needles with a strong birefringence in polarized light microscopy the detection of CPPD-crystals is more difficult. Those crystals are much smaller, showing weaker birefringence and are sometimes only seen with ordinary light microscopy. As both crystal diseases are mediated by IL-1 driven processes, the therapeutic intervention first target the acute inflammation consisting in colchicine, NSAIDs and glucocorticoids. Secondarily, in gout there are well established causal therapies to lower effectively serum urate levels below the target of 6 mg/dL (360 µmol/l). Unfortunately, those causal therapeutic options are still lacking in CPPD.

Written Descriptions

Many valid species can hide buried within prior taxonomic revisions. These need to be examined before the taxonomist embarks on the challenging task of naming new taxa. In this study we re-examine the synonyms complied by Abbott (1960) under Canarium urceus (Linné, 1758), examining each taxon for morphological clarity and distinctiveness. After considering the written descriptions and type material in light of prior revisions, we suggest that there are three valid species buried within the C. urceus synonymy of Abbott. All three species can be differentiated from C. urceus in general form, being less equi-triangulate and lacking the strong shoulder knobbing of that species. In addition, all three species are distinguishable by their distinctive aperture colouration. Canarium urceus possesses a typically black aperture, Canarium anatellum (Duclos, 1844) can be differentiated by its typically uniformly red/orange aperture, while Canarium incisum (Wood, 1828)is recognisable by the typically orange columella and outer lip, and a more triangular form. Strombus ustulatus form laevis Dodge, 1946 is the classical well-known form from the Philippines and elsewhere that is recognisable by its white columella. As the name laevis was preoccupied, we have renamed the species Canarium esculentum nomen novem. We assessed Strombus crassilabrum Anton, 1839 to be a nomen dubium. Further, our revision provides an improved hypothetical framework for the evolution and radiation of this most adaptable and variable of organisms, through increased clarity, and the re-circumscription of hitherto described taxa with distinctive morphotypes and separate biogeographical ranges.

During recent herbarium and field studies three names of Rubus sect. Corylifolii ser. Subcanescentes were re-assessed. Rubus macrostemonides was typified with a neotype specimen from Salzburg (Austria), and its identity with R. baruthicus was shown (the previous name has the priority). Its presence at the Austrian locus classicus was confirmed also recently, this locality represents the easternmost occurrence of the species. The name R. holosericeus was (mis)applied for a long time for a widespread taxon occurring southeast of the Alps that is not at all present in the original material. This name was lectotypified with a specimen from Styria (Austria) here as a hitherto overlooked regional species recently recorded in Austria, Hungary and Slovenia. The taxon that was formerly (mis)identified as R. holosericeus has proven to be identical to R. semitomentosus, which is lectotypified here with a specimen from Hungary. For both taxa clarified here is, beside a circumstantial assessment of the type material, an improved morphological characterization and circumscription of distribution and habitats presented.

Abstract Serologic experiments are described in which was studied the agglutination of leukocytes from donors representing various ABO, Rh, and Lewis erythrocyte groups an certain canine blood groups, in the presence of corresponding antisera. Appropriate mixing of antisera with leukocytes and erythrocytes from donors of different groups was seen to produce clumping of leukocytes which did not conform to the reactions of the erythrocytes from the leukocyte donor. When viewed under phase microscopy, certain of these leukocyte clumps, which appeared homogeneous with ordinary light microscopy were found to be clumps of leukocytes mixed with ghosts of erythrocytes reacting with the antibody present. Factors contributing to this apparently immunologically non-specific clumping were the presence of complement-fixing, potentially hemolytic antibody and thermolabile components of serum. A possible relationship with erythrophagocytosis is suggested. These observations indicate that certain results of this and other "leukoagglutination" technics, which have been interpreted as demonstrating the presence of A and B antigens on human leukocytes, deserve re-evaluation and emphasize the importance of developing methods of preparing homogeneous leukocyte suspensions.

Latest Eocene

ABSTRACTAll taxa of Orthoptera known from the latest Eocene deposits of the Isle of Wight are redescribed or discussed, based on the study of their type material. The following new taxa are described: Ontogryllus gen. nov., O. rossi sp. nov. (type species), Achetomorpha gen. nov., A. irregularis sp. nov. (type species), and Proeneopterotrypus gen. nov. The latter genus is here proposed for Pteroplistes danicus Rust, described from the Palaeocene/Eocene of Denmark, as this find is important for understanding the systematic position of the genus Eneopterotrypus Zeuner. Remarks about the taxonomy of the taxa studied, age of these deposits, and ecology are given.

Bertoloni published Florula guatimalensis in 1840, which is commonly cited as the original publication. However, our findings show that previous publications of Alessandrini of 1838 and 1840 include the original descriptions by Bertoloni which predate Florula guatimalensis. Among the 60 new taxa authored by Bertoloni, 26 were published in 1838 and 34 in 1840 by Alessandrini. Additionally, original drawings were discovered inside an old copy of Bertoloni’s Florula guatimalensis. Also a comparison between the original material from Bertoloni’s herbarium and his original drawings is here reported for the first time. The collection of Guatemalan plants studied by Antonio Bertoloni preserved at BOLO was analysed and is here discussed. The new combinations Odontonema corymbulosum and Lamourouxia barbata are proposed. A neotype for Aristolochia podocarpa and an epitype for Philadelphus myrtoides are here designated.

Abstract An in-depth study of the phylogeny and taxonomy of the corticioid genus Phlebiopsis (Phanerochaetaceae) was conducted. Phylogenetic analyses of the ITS1-5.8S-ITS2 and nrLSU sequences demonstrated that Phlebiopsis is a strongly supported clade that is distinct from its sister clade that includes Phaeophlebiopsis, Hapalopilus and Rhizochaete. Two genera, Australohydnum and Hjortstamia, are reduced to synonyms under Phlebiopsis because generic type species A. griseofuscescens and H. friesii, respectively, are embedded in the Phlebiopsis clade. Twenty-four lineages are resolved in the ITS phylogenetic tree of Phlebiopsis, including six new taxa from Sri Lanka and China — P. albescens, P. brunnea, P. cylindrospora, P. magnicystidiata, P. membranacea and P. sinensis. Five new combinations are proposed — Phaeophlebiopsis mussooriensis, Phlebiopsis bambusicola, P. dregeana, P. griseofuscescens and P. novae-granatae. Phlebiopsis crassa is a morphological species complex with three distinct lineages. Phlebiopsis lamprocystidiata is determined to be a later synonym of P. darjeelingensis. The new taxa are described, illustrated, and compared and contrasted to morphologically similar species. An emended description of Phlebiopsis is provided along with an identification key to 27 accepted species.
