Abstract:

A revision of the wild species in the genus Malus Mill. (Rosaceae) is presented based on numerical analyses and specimens from herbaria around the world, while cultivated species such as Malus domestica (Suckow) Borkh. are not included because of their complicated domestication history. Infra- and interspecific morphological variation and species delimitation are clarified based on Principal Component Analyses (PCA) and Cluster Analyses (UPGMA). We found that several morphological characters traditionally used to distinguish species have limited taxonomic value because of high phenotypic varia

AbstractA revision of the North American members of the Leptogium saturninum group (i.e. species with long lower-surface hairs, isidia, and usually smooth upper surface) is presented based on molecular phylogenetic analyses of mtSSU and nrITS sequence data, together with an extensive morphological study. Three species supported by both molecular and morphological characteristics are recognized: L. acadiense sp. nov.

Abstract:

The morphological variation of the Calceolaria tripartita species complex was evaluated using Principal Components Analysis (PCA) of morphological characters. Fourteen quantitative characters were measured on more than 250 herbarium specimens. The results suggest the recognition of three entities based on floral characters, especially stamen morphology. The distinction between C. mandoniana, C. chelidonioides and C. tripartita s.s. is not supported. The morphological differences between the closely related C. tripartita s.s. and C. chelidonioides were also analyzed using two characters previou

Abstract:

This paper reviews the evidence from Hittite on morphological and syntactic marking of direct addresses. It is shown that the standard description of Hoffner, and Melchert in 2008 needs a revision. Careful examination of a considerable body of texts shows a mismatch between morphological (vocative case) and syntactic (separate syntactic unit) marking of direct addresses to gods and men. The real taxonomy of direct addresses in Hittite is as follows: (a) morphologically marked vocatives within the main clause, (b) morphologically marked vocatives in a separate syntactic unit, (c) morphologicall

Abstract— Spiranthera (Rutaceae, Galipeeae) is a neotropical genus, recognizable mainly by the presence of trifoliate leaves, pentamerous flowers, exappendiculate filaments, spirally revolute anthers lacking a basal appendage, a campanulate disk, and anelongated gynophore. Species in this genus are mostly sciophilous treelets from South American rainforests, except for Spiranthera odoratissima, the most widespread species, which is a shrub inhabiting savannic formations and showing the widest morphological variation within the genus.

Abstract:

The taxonPetropedetesnewtoniiwas described in 1895 by Bocage, from Bioko Island (Equatorial Guinea). This taxon, whose holotype is lost, has been misidentified since Boulenger’s revision of the genus in 1900 and its relationships with other taxa (P.vulpiaeandP.johnstoni) is confusing. Currently,P.newtoniiis considered a synonym ofP.johnstoni. In this work, by revising morphological characters of non-webbedPetropedetesof Bioko, we demonstrate the morphological singularity of these specimens with respect toP.johnstoniandP.vulpiaeand their association with the namePetropedetesnewtonii.

The extra-Andean species of Vivianiaceae are here reviewed. We examine the morphological circumscription of Viviania albiflora (=Caesarea albiflora), evaluating all synonyms listed for this species. Although V. albiflora is a highly polymorphic species, especially regarding leaf morphology, a detailed morphological analysis leads us to conclude that V. linostigma, previously considered as one of its synonyms, needs to be accepted as a species. We noticed that the two species could be reliably differentiated by a trait such as tetramerous flowers for V. linostigma versus pentamerous flowers for

The study of the family in 2005–2017 indicates that the differences between two species Punica granatum L. and P. protopunica Balf. f. are insufficient to treat P. protopunica, an endemic of the Socotra Island, as a separate genus. The range of the variability of morphological features and caryological data suggest advisability to preserve the both species in the genus Punica L.

Abstract:

Water fleas (Crustacea: Cladocera) of the Family Bosminidae have been studied since the founding of paleolimnology and freshwater ecology. However, one species, Bosminopsis deitersi, stands out for its exceptional multicontinental range and broad ecological requirements. Here we use an integrated morphological and multilocus genetic approach to address the species problem in B. deitersi. We analyzed 32 populations of B. deitersi s. lat. Two nuclear and two mitochondrial loci were used to carry out the bGMYC, mPTP and STACEY algorithms for species delimitation. Detailed morphological study was

Abstract:

The Neotropical genus Acanthostyles R.M.King & H.Rob. (Asteraceae, Eupatorieae) occurs from northern Argentina up to northern Patagonia, southern Brazil, central and southern Bolivia, and Uruguay. Different taxonomic treatments have suggested that Acanthostyles might include two species (A. buniifolius (Hook. & Arn.) R.M.King & H.Rob. and A. saucechicoensis (Hieron.) R.M.King & H.Rob.), or even only a single, highly variable, species. Therefore, a detailed morphological study and a taxonomic revision of Acanthostyles were carried out.

Abstract:

For over two decades, assessments of geographic variation in mtDNA and small numbers of nuclear loci have revealed morphologically similar, but genetically divergent, intraspecific lineages in lizards from around the world. Subsequent morphological analyses often find subtle corresponding diagnostic characters to support the distinctiveness of lineages, but occasionally do not. In recent years it has become increasingly possible to survey geographic variation by sequencing thousands of loci, enabling more rigorous assessment of species boundaries across morphologically similar lineages.

Abstract:

The taxon Petropedetes newtonii was described in 1895 by Bocage, from Bioko Island (Equatorial Guinea). This taxon, whose holotype is lost, has been misidentified since Boulenger's revision of the genus in 1900 and its relationships with other taxa (P. vulpiae and P. johnstoni) is confusing. Currently, P. newtonii is considered a synonym of P. johnstoni. In this work, by revising morphological characters of non-webbed Petropedetes of Bioko, we demonstrate the morphological singularity of these specimens with respect to P. johnstoni and P. vulpiae and their association with the name Petropedete

Morphological boundaries between South American species of Euphrasia L. are controversial, rendering determination of specimens an arduous task. In this context, a comprehensive taxonomic revision of Euphrasia in South America is here provided for the first time. This study, based upon a classical morphological study of ca. 400 herbarium specimens, supports the recognition of eight species and one subspecies distributed in the Andean regions of Argentina, Bolivia, and Chile.

OBJECTIVE Despite significant advances in the medical field and shunt technology, shunt malfunction remains a nightmare of pediatric neurosurgeons. In this setting, the ability to preoperatively predict the probability of shunt malfunction is quite compelling. The authors have compared the preoperative radiological findings in obstructive hydrocephalus and the subsequent clinical course of the patient to determine any association with overall shunt outcome. METHODS This retrospective study included all pediatric patients (age < 18 years) who had undergone ventriculoperitoneal shunt insertio

Sollasella had been a poorly known, long forgotten taxon, placed incertae sedis in the order Hadromerida in the last major revision of the demosponges. It has recently been suggested to belong to Raspailiidae in the order Poecilosclerida due to striking morphological similarities. The present analysis verified this re-classification using molecular markers. Comparing 28S rDNA fragments of Sollasella cervicornis, a n

Abstract—A systematic revision of the tropical moss genus Papillaria was carried out by combining morphological studies with phylogenetic reconstructions based on molecular data from the plastid (trnL-F and rpl16) and the nuclear (ITS region) genomes. For the morphological study a set of qualitative and quantitative features was studied in over 2800 herbarium specimens, including the types, of all 55 previously accepted species in the genus. After revision, nine species of Papillaria were recognized, Papillaria crocea and P. flexicaulis which are broadly distributed in the tropics, P. africana
