Five new eriophyoid mite species from Zhejiang Province, China are described and illustrated: Diptacus coreanus sp. nov. from Litsea coreana H. Lév. (Lauraceae), Neorhynacus camphoratus sp. nov. from Cinnamomum camphora (L.) J. Presl (Lauraceae),  Rhinotergum boehmerius sp. nov. from Boehmeria gracilis C.H. Wright (Urticaceae), Rhyncaphytoptus cathayensis sp. nov from Carya cathayensis Sarg. (J...

Juglandaceae (walnut) is made up of several economically and ecologically valuable tree species. Chloroplasts, vitally important for plant growth, are also a rich source genetic evolutionary information. Both mutational pressure natural selection drivers codon usage pattern variation among genes. Here, we studied the chloroplast genomes in order to further our understanding biology evolution th...

Molecular phylogenetic analyses of ITS-LSU rDNA sequence data demonstrate that Melanconis species occurring on Juglandaceae are phylogenetically distinct from Melanconis s.str., and therefore the new genus Juglanconis is described. Morphologically, the genus Juglanconis differs from Melanconis by light to dark brown conidia with irregular verrucae on the inner surface of the conidial wall, whil...

BACKGROUND AND AIMS Unlike other taxa in Juglandaceae or in closely related families, which are anemophilous, Platycarya strobilacea has been suggested to be entomophilous. In Juglandaceae, Juglans and Carya show heterodichogamy, a reproductive strategy in which two morphs coexist in a population and undergo synchronous reciprocal sex changes. However, there has been no study focusing on hetero...

Vietnam is one of the main centers generic diversity for Juglandaceae worldwide. In this study, we present first time a province-wide distribution all 3 subfamilies, 7 genera, and 11 Vietnamese species, give an update on habitats their uses, current threats. are found throughout Vietnam. However, most species occur predominantly in northern part country between 600 1200 m. Some taxa range exten...
