BACKGROUND AND AIMS Plant species are considered as a good source of dietary proteins, although the nutritional quality of proteins depends on their amino acid composition. In this work the protein content and amino acid composition of nutlets of 21 Teucrium taxa (Lamiaceae) from Spain were analysed and their nutritional quality was compared with the minimum values established by the Food and A...

As part of a long-term investigation on the evolution of Passiflora L., we investigated the divergence ages of the genus and diversification of its subgenera, relating them with biogeographical and/or historical events, and other characteristics of this taxon. The main aim of the present work was to evaluate the biogeographic distribution of this genus to better understand its evolutionary hist...

The current classification of what used to be called Catapyrenium comprises eight genera belonging to distinct lineages in the Verrucariaceae. Previous phylogenetic studies have shown that the redefined genus Catapyrenium (Catapyrenium s. str.) is monophyletic and sister of Placidiopsis within the Staurothele group, but this relationship was based on only two species from each genus. We conduct...

Alpine plant radiations are common across all major mountain systems of the world, and have been regarded as main explanation for species diversity found within these areas. To study mechanisms behind origin this diversity, it is necessary to determine phylogenetic relationships boundaries in radiating alpine groups. The genus Dendrosenecio (Asteraceae) an iconic example a tropical-alpine radia...

The genus Cheilosia (Diptera: Syrphidae: Rhingiini) of Nepal is reviewed. We recorded 37 species Cheilosia, which 29 are described here. Twenty-six the new classified to a subgenus: (Cheilosia) angusta sp. nov., C. (C.) falcata hauseri maculata pica pilivena spinosa spuria weiperti (Montanocheila) albipicta (M.) alpha brevimontana gilva minuscula nigella pernigra picta (Floccocheila) collis (F....

Abstract Dorema (Apiaceae) includes 12 species distributed in the Irano-Turanian region. The genus differs from other genera of subfamily Apioideae having paniculate inflorescences with simple umbels. Recently, molecular phylogenetic analyses placed six Dorema, including generitype, Ferula , thus subsuming former into synonymy latter. remaining congeners have not been yet included analyses. Her...

Serjania is among the largest Neotropical genera of Sapindaceae and comprises ∼240 species. Traditionally, genus has been defined by its schizocarpic fruits separating into three distally winged mericarps. However, recent phylogenetic studies have revealed that fruit type not consistent within it also includes a few species having capsular were previously placed in other genera. A analysis pres...

Nymphaea has seven species already catalogued in the flood prone areas of the Brazilian Pantanal. However, some species remain difficult to identify and descriptions of the anatomy of vegetative organs are an important tool for infrageneric separation to aid in group taxonomy. The species collected in the Pantanal and prepared according to the usual techniques for anatomical studies showed simi...
