Linaria Mill. (Plantaginaceae) with about 160 spp. is the largest genus of the tribe Antirrhineae. We conducted phylogenetic analyses of nuclear ribosomal DNA internal transcribed spacer region (ITS) and chloroplast DNA (rpl32-trnL) sequence data to test the monophyly of currently recognized sections in Linaria. For this purpose 86 species representing seven sections of Linaria and one species ...

Phtheirospermum (Orobanchaceae), a hemiparasitic genus of Eastern Asia, is characterized by having long and viscous glandular hairs on stems and leaves. Despite this unifying character, previous phylogenetic analyses indicate that Phtheirospermum is polyphyletic, with Phtheirospermum japonicum allied with tribe Pedicularideae and members of the Ph. tenuisectum complex allied with members of tri...

Two novel species of Russula (Russulaceae, Russulales), namely indosenecis A.Ghosh, D.Chakr., K.Das & Buyck sp. nov. and R. pseudosenecis belonging to sect. Ingratae subg. Heterophyllidiae are proposed herein based on their morphological features nrITS-based phylogenetic inferences. Both belong the Asian ʻR. punctipes-senecisʼ complex Ingratae. The acrid was collected from subalpine forests...

Abstract The recently revised Geastrum minimum species complex in sect. subsect. Quadrifida revealed that the name G. is a nomen ambiguum and dubium was collectively used for at least two European (viz. granulosum marginatum ). During morphological revision of Hungarian materials labelled as , different crystal structures were found on endoperidial body some specimens than those characteristic ...

We sampled the 5' end of the granule-bound starch synthase gene (GBSSI or waxy) in Rosaceae, sequencing 108 clones from 18 species in 14 genera representing all four subfamilies (Amygdaloideae, Maloideae, Rosoideae, and Spiraeoideae), as well as four clones from Rhamnus catharticus (Rhamnaceae). This is the first phylogenetic study to use the 5' portion of this nuclear gene. Parsimony and maxim...

Some lineages of the orchid genus Ophrys exhibit among highest diversification rates reported so far. As a consequence such intense and rapid evolution, systematics taxonomy this remain unclear. A hybrid assembly approach based-on long- short-read genomic data allowed us to outperform classical methods successfully assemble whole plastid genomes for two new species Ophrys: O. aymoninii lutea. A...

Nigroboletus is proposed as a novel genus in family Boletaceae, subfamily Boletoideae, to include N. roseonigrescens, a new boletoid species from tropical environment in south-eastern China. Detailed morphological description, color pictures of both fresh basidiomes in habitat and dried material along with photomicrographs and line drawings of the main anatomical features are provided, supporte...

Indo-China floristic region is among the 34 richest floristic regions of the world, and its plant diversity is still under investigation. Here we report a new record of an aquatic plant, Potamogetondistinctus, from Myanmar, a part of the region, that is detected by means of DNA barcoding method. The molecular method further identified the other specimens as hybrids of Potamogeton: one is Potamo...

Meconopsis is a genus native to the high elevation habitats that range from the western Himalaya eastward to the Hengduan Mountains (China). The genus has been the subject of several taxonomic treatments and monographs by generations of botanists, which has led to a long and confusing taxonomic history with inconsistent species concepts and conflicting interpretations of relationships among nam...
