The results of a study of all genera in the family Elaeocarpaceae as found in Papuasia are presented. Keys to all accepted taxa are provided, many epithets are reduced to synonymy and an attempt is made to interpret the remaining 28 specific epithets that are inadequately described and whose types are lost or unavailable. The following new taxa are described and illustrated: Aceratium sinuatum, A. tomenrosum, Dubouzetia galorei, D. kairoi, Elaeocarpus badius, E. bakaianus, E, buderi, E. dolichostylus ssp. collinus, E. marafunganus, E. murukkai, E. neobritannicus, Sericolea calophylla ssp. grossiserrata, S. collinsii, S. pachyphylla, Sloanea pulchra ssp. morobensis, S. pulleniana, S. streimannii. Notes on morphological features of interest are given.

Radiation Treatments

Flavonoids are important secondary metabolites, whose content and composition such as anthocyanin and flavonol have been associated with fruit quality and affect fruit coloration. Crabapple (Malus spp.), with rich color and nutritive value, belongs to the family M. genus of the Rosaceae family, and it is widely used in landscape for its rich flavonoid compositions. Radiation mutagenesis breeding may increase the gene mutation frequency and enhance diversity of species, so it is a predominant approach for plant germplasm innovation. However, the changes of crabapple morphological characteristics and flavonoid compositions by radiation are not clear. In this study, we employed 60Coγ radiation to M.cv. ‘Royalty’ crabapple, and then surveyed the changes of leaves and flowers in the growth and morphology traits, color parameters, flavonoid composition, and the genetic diversity. The result found that 60Coγ radiation decreased plant height, stem diameter and leaf and flower areas. And it promoted the flavonoids accumulation in leaves, but inhibited that in flowers. Additionally, 60Coγ radiation improved DNA diversity. W60-7, W40-2 and W40-5 plants showed clear phenotypic variation by AFLP analysis. These results provide evidence that mutagenesis breeding may change the morphological features and flavonoid compositions, and expand crabapple germplasm resources and improve its application value.

New genus and species of burrowing sea anemones of the family Halcampidae, Gorgonactis marisalbi gen. et sp. nov., are described from the White Sea (Chupa Bay). The new taxa are characterised by unique characters not found in other members of this family: a simple, strong marginal sphincter, very long tentacles and their large spirocysts.

A survey of freshwater fungi on submerged wood in China and Thailand resulted in the collection of three species in Dictyocheirospora and four species in Dictyosporium including two new species in the latter genus. Morphological characters and phylogenetic analyses based on ITS, LSU and TEF1α sequence data support their placement in Dictyocheirospora and Dictyosporium (Dothideomycetes). An updated backbone tree is provided for the family Dothideomycetes. Descriptions and illustrations of the new taxa and re-collections are provided. Four new combinations are proposed for Dictyocheirospora.

Ocala Limestone

Oyenaster oblidus, Ocalaster timucum, and Ocalaster seloyi are new genera and species of the family Goniasteridae (Asteroidea) described from the Eocene Ocala Limestone of Florida. Although the fossil record of asteroids is sketchy, goniasterids appear to have been important contributors to marine communities since at least the Middle Jurassic. Similarities between living goniasterids and their fossil precursors indicate that plesiomorphy and convergence have been important in family history, and as a result, taxonomic interpretation is challenging. Even partial fossil goniasterids are rare, forcing systematists to rely heavily on isolated marginal ossicles, although some authors have expressed the need for caution. Building around three new taxa, we suggest that broader approaches can aid systematic interpretation of all crown-group asteroids. We also suggest that the inevitably idiosyncratic interpretations of marginal-based systematics can be partially tested using blind evaluations.

In recent years, an increase in knowledge about the diversity and biogeography of Brazilian Cladocera fauna has been evident. To keep up with these changes, it is opportune to carry out an update of the taxonomy and biogeography for the main cladoceran groups. Since 2008, some progress has been observed in Ilyocryptidae, with reports of four new taxa. In this study, an updated checklist of Ilyocryptidae from Brazil is provided, with a diagnosis for each cited taxon, as well as an identification key. Some of these taxa are considered rare; however, this issue might be an artifact of sampling. As this is the first in a series of papers compiling current information about Brazilian Cladocera, an identification key to orders and families occurring in Brazil is also provided.

The genus Senecio L. is one of the largest genera of flowering plants and is an important member of the tribe Senecioneae (Asteraceae). Phenotypic information, including a broad range of morphological characters is very crucial for phylogenetic reconsideration of any family, tribe or genus. In the family Asteraceae, very little attention has been paid to cypselar diversity, though it is regarded as taxonomically valuable. A sincere attempt has been made to study detailed cypselas macro and micro-morphological features of four species of Senecio L. These diacritical features could be used to strengthen current inter-specific concept of Senecio L.DOI: http://dx.doi.org/10.3329/bjpt.v21i1.19251Bangladesh J. Plant Taxon. 21(1): 13-17, 2014 (June)

Abstract We describe two new genera of Triassic Aviculopectinoidea: Cristaflabellum n. gen., which is biconvex and has a strongly plicate shell, and Globodiscus n. gen., which is equiconvex and externally smooth or nearly so. Globodiscus contains the new species G. kiliani n. gen. n. sp. and G. vinzenti n. gen. n. sp. In order to make the taxonomic concept of the superfamily Aviculopectinoidea more consistent with that of its sister group Pectinoidea (scallops), we use tribes rather than families or subfamilies for accommodating the new taxa. Cristaflabellum is placed in the tribe Antijanirini (previously family Antijaniridae), whereas Globodiscus is made the type genus of the new tribe Globodiscini. Both tribes are placed within the family Aviculopectinidae, which is revised to include both equiconvex and inequiconvex taxa. We suggest that tribes are a more appropriate taxonomic rank for many of the previously erected species-poor families and subfamilies of Aviculopectinoidea.

Polyphasic Characterization

Following Recommendation 30b of the Bacteriological Code (1990 Revision), a proposal of minimal standards for describing new taxa within the family Halomonadaceae is presented. An effort has been made to evaluate as many different approaches as possible, not only the most conventional ones, to ensure that a rich polyphasic characterization is given. Comments are given on the advantages of each particular technique. The minimal standards are considered as guidelines for authors to prepare descriptions of novel taxa. The proposals presented here have been endorsed by the International Committee on Systematics of Prokaryotes Subcommittee on the Taxonomy of Halomonadaceae.
