A new genus, Simonachne E.J.Thomps. is described and Ancistrachne maidenii (A.A.Ham.) Vickery transferred to it as The subtribe Cleistochloinae composed of four genera, Calyptochloa, Cleistochloa, Dimorphochloa Simonachne, united by distinctive morphology that associated with reproductive dimorphism. Phenetic analyses were used examine the similarities taxa test consistency results variation in...

A multivariate statistical analysis was performed on morphological characters of sixty-one populations of Avena eriantha Dur. A. clauda Dur., A. barbata Pott ex Link., A. wiestii Steud., A. fatua L., A. sterilis ssp. ludoviciana L. and A. sativa L. Factor analysis revealed that intraspecific morphological variations are due to quantitative characters. Interspecific as well as intersectional rel...

Abstract. Based on the material collected during fieldwork seasons from 1996 to 2007 in amount of 223 specimens, we studied phenetic relationships and taxonomic structure genus Cyphocottus. Two valid species, C. megalops eurystomus, within boundaries established by D.N. Taliev (1955) were confirmed Interspecific differences eurystomus are manifested greater values interorbital distance, height ...

Restriction fragment length polymorphisms (RFLP) of the intergenic spacer region (IGS) of rDNA and random amplified polymorphic DNA (RAPD) markers were used to survey genetic variability among 181 isolates of Sclerotinia homoeocarpa from Ontario and 10 isolates from Japan. RAPD and IGS-RFLP analyses revealed polymorphisms within and between populations of S. homoeocarpa, distinguishing 151 geno...

Pairwise difference analysis is a phenetic method that groups taxa on the basis of the number of differences they exhibit. Recently, pairwise difference analysis has been used to investigate the phylogenetic relationships of hominid fossils at the centre of the modern human origins debate. It has been argued that the results of these analyses disprove the African replacement model of modern hum...

The hominid temporal bone offers a complex array of morphology that is linked to several different functional systems. Its frequent preservation in the fossil record gives the temporal bone added significance in the study of human evolution, but its morphology has proven difficult to quantify. In this study we use techniques of 3D geometric morphometrics to quantify differences among humans and...

Phenetic analysis of morphological characters in different species of Onobrychis Miller sect. Hymenobrychis DC. (Fabaceae), classified them in two main groups based on corolla features. To determine the phylogenetic relationships among the 13 species, chloroplast DNA sequences were used. Analysis of these data resulted in a well-resolved and well-supported phylogeny. Phylogenies generated by ma...
