Hieracium sect. Oreadea (Asteraceae) in Sweden – from a complete mess to a preliminary taxonomic classification

Among Swedish Hieracium sect. Oreadea (Fr.) Arv.‐Touv., more than 100 taxa have been recognized by various experts but, except for a regional monograph from 1894 there are no thorough published revisions of the group and many of the names have never been validly published. At the same time, some of the oldest names have been variously applied to morphologically clearly different species. In the present study, 5000 specimens in Swedish herbaria have been revised using both traditional and statistical morphometric methods and the complicated nomenclature has been disentangled. Twenty‐eight species are recognized and described with diagnostic keys and illustrations aiding identification and their known distributions are mapped. Six species are described as new to science (viz. H. marinum T. Tyler, H. eulasium Dahlst. ex T. Tyler, H. victoriae T. Tyler, H. falcifolium Johanss. ex T. Tyler, H. guldbergense Folin ex T. Tyler and H. hispidosum Dahlst. ex T. Tyler) and 3 additional names are raised to the specific rank (viz. H. gigantocybe (Dahlst.) T. Tyler, H. hilare (Dahlst. ex Omang) T. Tyler and H. tanyphyllum (Dahlst. ex Zahn) T. Tyler). Lectotypes are designated for 50 names based on material from Sweden, Norway or Finland and one name is neotypified. Except for a few infraspecific names for which all original material appears to be lost, all names based on material from Sweden are typified. However, it is concluded that albeit the number of taxa is relatively low, the species of H. sect. Oreadea are morphologically less distinct and clear‐cut than those of other widespread Scandinavian sections of the genus. Many of the characters that are most important in other sections of the genus are either invariable or unreliable in H. sect. Oreadea. Thus, the taxonomy has to rely on characters more subjected to environmentally‐induced modification. Furthermore, members of this section exhibit great morphological plasticity, possibly connected to their preference for exposed rocky habitats where the environmental conditions may be both severe and unpredictable.In addition, due to their ecological demands, they are confined to habitats that have always been both strongly fragmented and restricted in size giving rise to multiple small and locally adapted local populations. The section is here circumscribed in agreement with previous Scandinavian authors, i.e. including both the H. schmidtii‐group sometimes referred to H. sect. Stelligera and the H. norvegicum group approaching H. sect. Tridentata, but it is concluded that the section is relatively heterogeneous and that further studies aiming at the identification of more natural supraspecific taxa are much needed.     

Typification of three names in Antirrhinum (Plantaginaceae: Antirrhineae)

Typification of the names Antirrhinum barrelieri Boreau, A. controversum Pau and A. litigiosum Pau (Antirrhineae, Plantaginaceae) is needed to clarify the use and concept of these three names. The origin of a misinterpretation of the name A. barrelieri, which conditioned the subsequent use of these three names, is discussed. The previous ‘lectotype’ of A. barrelieri designated by Rothmaler from a Barrelier's illustration is shown to be ineffective, being contrary to Art. 9.12 of the ICN, and therefore a lectotype is designated from a syntype preserved in the herbarium of the Muséum des sciences naturelles d'Angers (France) at ANG. The Pau's names A. controversum and A. litigiosum have not been typified before, and lectotypes are here designated from specimens preserved at P and MA, respectively. As a consequence, the name A. litigiosum should be treated as a later heterotypic synonym of A. barrelieri.     

The Music Indici: its authors, types and localities

The sixty new taxa described in Musci Indici are reviewed. As a result of validation of 54 of these by plates alone, authorities, original specimens and provenance of many have been widely misinterpreted. Evidence from published material, unpublished correspondence and herbarium material demonstrates that W. H. Harvey (1836) is the sole validating author of most of the names; three were validated by J. D. Hooker in 1837, and two names jointly by J. D. Hooker and Harvey in 1840. None was validated by W. J. Hooker, in the past often considered to be the author of some of the names. It is shown that Musci Indici names should be typified by lectotypes; recent typifications of four of the names by ‘holotypes’ and six out of eight published ‘lectotypes’ are untenable as the specimens selected were not original material studied by Harvey, and should be superseded by new lectotypes. Five specimens are selected as new lectotypes. Original material, mostly in Harvey's herbarium in TCD, is identified as most suitable for future lectotypification of the other names. Types for the three names based solely on Royle material are located in LIV and BM. Original Harvey material is also preserved in GL, but most of the Wallich collections in BM, E and elsewhere are not part of the original material. For Neckera blanda no suitable type specimen was located; the original published plate is selected as lectotype with a specimen in BM as a supporting ‘epitype’. Many of the original localities published in 1840 as ‘Nepal’ are shown to be erroneous. As far as possible these are corrected but for some taxa provenance remains doubtful. Twenty-two of the new names are shown not to have been based on material from Nepal; as a result ten species (Acanthorrhynchium papillatum, Brachythecium kamounense, Chaetomitriopsis glaucocarpa, Meiothecium microcarpum, Mitthyridium repens, Rozea fulva, Splachnobryum flaccidum, Sterophyllum radiculosum, Trichosteleum boschii and Trismegistia lancifolia) and Trismegistia lancifolia) are deleted from the Nepal checklist. Twenty-eight of the new species are considered to be reliably based on material from Nepal, and a further five doubtfully so. Rozea microcarpa Broth. is shown to be an synonym of R. fulva (Harv.) M. Fleisch. Past taxonomic confusion between Hypnum cordatum Harv. and Neckera cordata [Hook. ex] Harv. is untangled; the first is shown to be a synonym of Eurhynchium hians (Hedw.) Sande Lac. and the second is the basionym of Penzigiella cordata (Harv.) M. Fleisch.     

Name typification of Umbelliferae taxa described by Joseph Franz Freyn

Thirty-three new species and 12 new infraspecific taxa of the Umbelliferae have been described by Bohemian botanist Joseph Franz Freyn (1845–1903). The names of these taxa are typified, in most cases by material preserved at the Herbarium of the Moravian Museum (BRNM) in Brno. The names of nine species proposed by Freyn are accepted in the present-day nomenclature of the family; five others are the basionyms of presently accepted names. Type material from BRNM has enabled rehabilitation of the specific status of Angelica brachyradia Freyn from Bosnia and Pastinaca dentata Freyn & Sint. from Turkey. A new nomenclatural combination is proposed (Taeniopetalum urbani (Freyn & Sint. ex H. Wolff) Pimenov). Notes on the distribution of the taxa concerned are added.     

Supraspecific division of the genusJuncus (Juncaceae)

A new classification of the genusJuncus (Juncaceae) is presented. The genus is divided into two subgenera, characterized by the presence/absence of bracteoles and the structure of inflorescence. Lower rank subdivisions, sections, generally correspond to the traditionally recognized subgenera introduced by Buchenau. A new name is introduced for what has been called subg. (sect.)Ensifolii, Juncus sect.Iridifolii. A checklist of supraspecific names inJuncus, with typification and references to the sectional names accepted, is presented in the Appendix.     

THE ENGLISH NAMES OF THE AFROTROPICAL NIGHTJARS (CAPRIMULGIDAE)

Jackson, H. D. 1993. The English names of the Afrotropical nightjars (Caprimulgidae). Ostrich 64: 148–159.

At least 172 different English names have been used on the nightjars of Africa and its related islands, including Madagascar. A review of the literature chronicles the name changes within each species. Problems created by some duplication and transposition of names between species are discussed. A key to all the names is provided by an alphabetical list cross referenced to the species concerned. The orthography of names is discussed and it is recommended that all animal names be capitalized and freed of unnecessary hyphens. The nightjar names used in The Birds of Africa are accepted as the standard to be followed subject to a few changes.     

Are species names proper names?

The nature of species names has been a source of controversy, and has played a role in developing ideas about the status of species, such as the species‐as‐individuals hypothesis. Some argue that species names are Millian proper names: names that have no meaning. Others have countered that species names are Millian general names that have stipulative definitions. Here I argue that species names belong to neither category. In particular, unlike Millian proper names, species names have unique referents and are connotative. Further, species names are names of intension that, unlike Millian general names, refer to specific collective entities. Because species names have unique properties not associated with Millian general or proper names, but recognizing the similarity to proper names in most respects, I propose that they be categorized as extra‐proper names.
     

HLA-B alleles of the Cayapa of Ecuador: new B39 and B15 alleles

Recent data suggest that HLA-B locus alleles can evolve quickly in native South American populations. To investigate further this phenomenon of new HLA-B variants among Amerindians, we studied samples from another South American tribe, the Cayapa from Ecuador. We selected individuals for HLA-B molecular typing based upon their HLA class II typing results. Three new variants of HLA-B39 and one new variant of HLA-B15 were found in the Cayapa: HLA-B ^*3905, HLA-B^*3906, HLA-B^*3907, and HLA-B ^*1522. A total of thirteen new HLA-B alleles have now been found in the four South American tribes studied. Each of these four tribes studied, including the Cayapa, had novel alleles that were not found in any of the other tribes, suggesting that many of these new HLA-B alleles may have evolved since the Paleo-Indians originally populated South America. Each of these 13 new alleles contained predicted amino acid replacements that were located in the peptide binding site. These amino acid replacements may affect the sequence motif of the bound peptides, suggesting that these new alleles have been maintained by selection. New allelic variants have been found for all common HLA-B locus antigenic groups present in South American tribes with the exception of B48. In spite of its high frequency in South American tribes, no evidence for variants of B48 has been found in all the Amerindians studied, suggesting that B48 may have unique characteristics among the B locus alleles.The nucleotide sequence data reported in this paper have been submitted to the GenBank nucleotide sequence database and have been assigned the accession numbers U14756 (HLA-B ^*1522), U15683 (HLA-B ^*3905), U15639 (HLA-B ^*3906), and U15640 (HLA-B ^*3907)The names listed for these sequences were officially assigned by the WHO nomenclature Committee in September 1994, B ^*3905, and November 1994, B ^*1522, B^*3906, and B ^*3907. This follows the agreed policy that, subject to the conditions stated in the most recent Nomenclature Report (Bodmer et al. 1994), names will be assigned to the new sequences as they are identified. Lists of such new names will be published in the following WHO Nomenclature Report.

This follows the agreed policy that, subject to the conditions stated in the most recent Nomenclature Report (WHO Nomenclature Committee for factors of the HLA system, 1991), names will be assigned to new sequences as they are identified. List of such new names will be published in the following WHO Nomenclature Report.     

Species concepts for trypanosomes: from morphological to molecular definitions?

The way species and subspecies names are applied in African trypanosomes of subgenera Trypanozoon and Nannomonas is reviewed in the light of data from molecular taxonomy. In subgenus Trypanozoon the taxonomic importance of pathogenicity, host range and distribution appear to have been inflated relative to actual levels of genetic divergence. The opposite is true for subgenus Nannomonas, where current taxonomic usage badly underrepresents genetic diversity. Data from molecular characterisation studies are revealing a growing number of genotypes, which may represent distinct taxa. Unfortunately few of these genotypes are yet supported by sufficient biological data to be recognized taxonomically. But we may be missing fundamental epidemiological information, because of our inability to distinguish these trypanosomes in host blood morphologically or in tsetse by their developmental cycle. Molecular taxonomy has led the way in identifying these new genotypes and now offers the key to elucidating the biology of these organisms.     

Wissadula Proliferation in Jamaica

In Jamaica, phloem-restricted prokaryotes were found associated with a little leaf proliferation disease of Wissadula periplocifolia (L.) C. Presl. ex Thwaites. Electron microscopy of single ultrathin sections revealed circular, ovate and elongate profiles 120—500 nm in diameter/width and 125—4200 nm long. Most were bound by a double membrane and resembled the phloem-restricted rickettsialike organisms associated with a small number of other plant diseases; others which were peripherally ill-defined or without an obvious double membrane were indistinguishable from mycoplasmalike organisms. Further work is required to elucidate their taxonomic status and possible role in the aetiology of the disease. No potential aetiological agent was discovered for a symptomatologically similar disease of Abuliton hulseanum (Torr. & A. Gray) Torr. ex Chapm. which accurred intermixed with the Wissadula disease. The names Wissadula proliferation and Abutilon proliferation have been used to describe these newly recorded diseases.     

Taxonomic review of the New World tamarins (Primates: Callitrichidae)

Twelve generic names have been ascribed to the New World tamarins but all are currently placed in just one: Saguinus Hoffmannsegg, 1807. Based on geographical distributions, morphology, and pelage patterns and coloration, they have been divided into six species groups: (1) nigricollis, (2) mystax, (3) midas, (4) inustus, (5) bicolor and (6) oedipus. Molecular phylogenetic studies have validated five of these groups; each are distinct clades. Saguinus inustus is embedded in the mystax group. Genetic studies show that tamarins are sister to all other callitrichids, diverging 15?13 Ma. The small‐bodied nigricollis group diverged from the remaining, larger tamarins 11?8 Ma, and the mystax group diverged 7?6 Ma; these radiations are older than those of the marmosets (Callithrix, Cebuella, Mico), which began to diversify 6?5 Ma. The oedipus group diverged from the midas and bicolor groups 5?4 Ma. We review recent taxonomic changes and summarize the history of the generic names. Taking into account the Late Miocene divergence time (11?8 Ma) between the large‐ and small‐bodied tamarin lineages, the small size of the nigricollis group species when compared with other tamarins, and the sympatry of the nigricollis group species with the larger mystax group species, we argue that the nigricollis group be recognized as a distinct genus: Leontocebus Wagner, 1839.     

Ravens (Corvus corax corax L.) in the British landscape: a thousand years of ecological biogeography in place-names

Abstract Aim To investigate the information content of place‐names regarding the habits, habitat and biogeography of ravens in Britain over the past millennium. Location England, Scotland and Wales. Methods Linguistic and ecological analysis of over 400 British place‐names that have a putative ‘raven’ derivation. Results Most of the ‘raven’ place‐names are Old English in origin. Some of these (a minority), however, derive from personal names. The derivations of most names reflect landscape rather than man‐made features; the majority relating to high, craggy ground or coastal features, a minority to wooded situations or human habitations. In lowland Scotland and the Scottish borders the colloquial name corbie dominates ‘raven’ place‐names, perhaps reflecting French influence. In the Highlands and the Western Isles the Gaelic fitheach and its derivatives are predominant. Relatively fewer place‐names that have ‘raven’ roots have been educed in other parts of the Celtic West, i.e. Wales and Cornwall (only one traced in the latter). Main conclusions Comparison of the geographical distribution of ‘raven’‐derived place‐names with the present‐day distribution of the species in Britain reveals the extent of the contraction in the raven's range to the West over historical time, most notably during theprevious two centuries, associated with changed land‐management practices in particular.     

Ichnology of the Early Cambrian Tal Group,Nigalidhar Syncline,Lesser Himalaya,India

Though trace fossils have been recorded from the Tal Group of the Krol-Tal Belt by earlier workers, most of the records are at generic level only. This paper describes, in detail, 24 ichnospecies from 20 ichnogenera, some of which are being reported for the first time, from the Ganog and Koti Dhaman sections of the Nigalidhar Syncline, H.P. Based on the ichnostratigraphic and ichnofabric analyses these ichnofossils have been categorized into three ichnoassemblages, namely Palaeophycus-Phycodes, Daedalus-Phycodes, and Cruziana Ichnoassemblages. An attempt has also been made for correlation of the Tal sections with other Precambrian-Cambrian sections of the world.     

A SYNOPSIS OF NORTH AMERICAN ASTERS: THE SUBGENERA,SECTIONS AND SUBSECTIONS OF ASTER AND LASALLEA

Traditional treatments of Aster were found unsatisfactory in predicting cytological and morphological characteristics of members of various subgenera, sections and subsections of different authors. A realignment of species into these infrageneric categories is presented and is based on sets of shared morphological characteristics of roots or rhizomes, leaves, and phyllaries. Eight subgenera are recognised in Aster. Subgenus Aster is divided into five sections on morphological characteristics: three have X = 9, one has X = 8 and one has X = 7. Subgenus Aster section Dumosi has been redefined and contains all the X = 8 species. Ten X = 5 species and one X = 4 species previously classified in up to six sections of subgenus Aster were found to be morphologically and cytologically related to each other, but unrelated to the other species of Aster. These eleven species have been assigned to the genus Lasallea sensu Semple & Brouillet. Lasallea has been divided in sections and subsections with new combinations presented in this paper.
