Studies of New Zealand Hepaticae. 1–6

Six New Zealand species are treated. 1. The correct basionym reference forBazzania hochstetteri (Reichardt) Hodgson is Reichardt (1866). A key to the New Zealand vittate species ofBazzania is included. 2. The correct citation forBazzania mittenii (Stephani) Stephani is given. 3.Lepidozia leptodictyon Herzog is placed in the synonymy ofPseudocephalozia lepidozioides R. Schuster. 4.Metahygrobiella chilensis Engel & Schuster is a new name forCephalozia heteroica Schuster & Engel. 5.Metzgeria alpina Schuster & Engel is described as new. 6. The correct citation forPachyglossa Herzog is Herzog (1952).     

Carapichea guianensis: the correct name for Psychotria carapichea (Rubiaceae), with a correction on the authority of P. carapichea, and a new combination in Carapichea

The correct name forPsychotria carapichea isCarapichea guianensis. Also, the authority ofPsychotria carapichea was previously incorrectly cited, because of an oversight of the illegitimacy ofTapogomea carapichea Poir. The complex taxonomic history of this species is analyzed, and the authority of the binomial is correctly cited. In addition,P. ligularis, which was treated as closely related toC. guianensis in previous publications, is transferred toCarapichea and it is now known asCarapichea ligularis.     

Maksymilianites, a new name forSyringella Nowiński, 1970 (Anthozoa, Tabulata) preoccupied bySyringella Schmidt, 1868 (Porifera)

A new name,Maksymilianites nom. nov. is proposed as a replacing name forSyringella Nowiński, 1970 (Anthozoa, Tabulata), monospecific genus from the Middle/Upper Devonian of Poland preoccupied bySyringella Schmidt, 1868 (Porifera).     

A note on Mimosa invisa C. Martius ex Colla and M. Invisa C. Martius (Mimosaceae)

Mimosa invisa C. Martius (1837) is not, as long supposed, a superfluous duplication ofM. invisa C. Martius ex Colla (1834), but a heterotypic posterior homonym and therefore illegitimate.Mimosa invisa C. Martius ex Colla is the earliest valid name forM. rhodostachya (Benth.) Benth. (1875). The correct name forM. invisa C. Martius isM. diplotricha C. Wright ex Sauvalle (1868).     

Gurania lobata (Cucurbitaceae), a new combination for an overlooked Linnaean name

The new combinationGurania lobata (Cucurbitaceae) is made forAnguria lobata, an overlooked Linnaean name published in the original edition ofPlantae Surinamenses, andG. spinulosa is treated as synonymous with this species.     

Rediscovery of Ardisia gigantifolia and the reinstatement of A. kteniophylla (Primulaceae) – finding the correct name for the Chinese medicinal plant ’Zou Ma Tai’

With the rediscovery of Ardisia gigantifolia, the long‐standing confusion with A. pseudoverticillata, A. kteniophylla and A. dasyrhizomatica owing to the misinterpretation of the type of A. gigantifolia is clarified. It is shown that A. dasyrhizomatica is a later synonym of A. gigantifolia, while A. kteniophylla and A. pseudoverticillata are conspecific and represent another species for which A. kteniophylla is the earliest name available. Ardisia kteniophylla is the correct scientific name for the Chinese medicinal plant ’Zou Ma Tai’.     

Typification of Crataegus crus-galli L. (Rosaceae) and nomenclatural notes on some related species of hawthorn

Lectotypification of Crataegus crus-galli permits the common ten-stamened entity of the northern United States and adjacent Canada to retain its name. The correct name for the related 20-stamen form, usually called C. fontanesiana, is C. tenax. Crataegus persimilis, lectotypified here, is shown to occur in Ontario as well as New York, having been previously misidentified as C. ?bushii and C. prunifolia in Ontario. A horticultural taxon usually (but improperly) called C. prunifolia is provided with a new cultivar name.     

Arnoglossus macrolophus Alcock (Pleuronectiformes: Bothidae); a valid species distinct fromA. tapeinosomus (Bleeker)

The holotype of a bothid flounder,Arnoglossus tapeinosomus (Bleeker, 1866), was re-examined and found to bear none of the diagnostic characters ascribed by many authors to the species. In addition, the shape of the prevomer was clearly different between the holotype and 18 specimens supposedly“A. tapeinosomus.” A. macrolophus Alcock, 1889, which was synonymized underA. tapeinosomus by Weber and de Beaufort (1929), is considered as a valid replacement name for“A. tapeinosomus,” because of the elongated anterior rays in the dorsal fin and a large, dark spot on the posterior dorsal and anal fin bases.A. tapeinosomus is redescribed from the holotype.     

Notes on neotropical Amanoa (Euphorbiaceae)

Lectotypes are designated forAmanoa caribaea Krug & Urban andA. guianensis Aublet; presumed syntypes of the latter taxon are shown to be heterogeneous by inclusion of a previously unrecognized species. Four new species ofAmanoa are described:A. congesta from French Guiana and northeastern Brazil;A. gracillima from Manaus, Brazil;A. nanayensis from Amazonian Peru and adjacent Colombia and Brazil; andA neglecta from French Guiana and Surinam.Amanoa sinuosa is proposed as a new name for the later homonymA. robusta Leal. A key to the 13 neotropical species is presented.     

The species of Erysipelothrix

Summary The three speciesErysipelothrix rhusiopathiae, E. erysipeloidis, andE. muriseptica should be united into one, to which the oldest valid specific name should be applied. The correct name isErysipelothrix insidiosa.     

Predation ofOligonychus pratensis [Aca.: Tetranychidae] byPhytoseiulus persimilis andAmblyseius californicus [Aca.: Phytoseiidae] under controlled laboratory conditions

The predator efficacy ofPhytoseiulus persimilis Athias-Henriot andAmblyseius californicus (McGregor) (Acarina: Phytoseiidae) when feeding on the Banks grass mite (BGM),Oligonychus pratensis (Banks) (Tetranychidae), was compared under controlled laboratory conditions. Predation byP. persimilis andA. californicus reduced the BGM densities by 60% and 28%, respectively. In general, phytoseiids preferentially fed upon the more abundant instars. Ovipositional rates forP. persimilis while feeding on BGM approximated rates when feeding onTetranychus spp. The use of a trade name is not an endorsement by Texas A&M University.     

Comparative study of the response ofAzotobacter vinelandii andAcetobacter diazotrophicus to changes in pH

Summary Curves were established for the pH response of respiration on eleven substrates byAzotobacter vinelandii andAcetobacter diazotrophicus. With every substrate the optimal pH forA. diazotrophicus was lower than forA. vinelandii. The optimal hydrogen ion concentration forA. diazotrophicus was 5 fold to 365 fold greater than forA. vinelandii depending upon the substrate. In general,A. diazotrophicus supports respiration over a wider pH range than doesA. vinelandii.Dedicated to the memory of Professor John G. Torrey     

Typification of Sphagnum capillifolium (Ehrh.) Hedw.

Abstract

On the basis of the protologue, the name Sphagnum nemoreum Scop. is treated as a nomen dubium and consequently is rejected. S. capillifolium (Ehrh.) Hedw. is lectotypified through a Dillenius specimen, and is proposed to be adopted as the correct name of this species.     

A biometrical analysis of the South AmericanElymus glaucescens complex (Poaceae: Triticeae)

Based on a simple multivariate analysis of the morphology of theAgropyron pubiflorum complex—A. patagonicum, A. antarcticum, A. fuegianum, andA. magellanicum—the variation pattern is shown to be clinal, and all taxa are included in a single, variable species. Currently the majority of species ofAgropyron is included inElymus and the correct name of this species isE. glaucescens.     

Modulation of the molecular size of humic substances by organic acids of the root exudates

Foliar phosphorus content and mycorrhizal infection of dipterocarp seedlings growing in a 61-year-old forest plantation (site A) and a selectively logged forest (site B) were determined. Mycorrhizal infection levels were high–83.7% forShorea bracteolata and 95.0% forS. leprosula at site A, and 77.8% forS. leprosula and 86.3% forS. curtisii at site B. The seedlings all had similar foliar phosphorus contents although available soil phosphorus at site B was half that at site A. Significant correlations were obtained between foliar phosphorus content and percentage mycorrhizal infection at site B only.     

Carex tomentosa versus C. filiformis (Cyperaceae): the long‐standing debate comes to its happy end

The type of Carex filiformis is an illustration, which is pluri‐interpretable and therefore an epitype is designated here. As epitypified, C. filiformis L. becomes synonymous with Carex montana L. (the latter getting priority), and therefore not the correct name for Carex tomentosa L. as stated by Nelmes and other authors. Carex tomentosa is the accepted name for the taxon sometimes referred to as C. filiformis.
