The snake gourd genus, Trichosanthes, is the largest genus in the Cucurbitaceae family, with over 90 species. Recent molecular phylogenetic data have indicated that the genus Gymnopetalum is to be merged with Trichosanthes to maintain monophyly. A revised infrageneric classification of Trichosanthes including Gymnopetalum is proposed with two subgenera, (I) subg. Scotanthus comb. nov. and (II) ...

BACKGROUND Water influences various physiological and ecological processes of plants in different ecosystems, especially in desert ecosystems. The purpose of this study is to investigate the response of physiological and morphological acclimation of two shrubs Haloxylon ammodendron and Calligonum mongolicunl to variations in irrigation intervals. METHODOLOGY/PRINCIPAL FINDINGS The irrigation ...

Five new supraspecific taxa of Scapania are proposed, Scapania subg. Gracilidae, Scapania subg. Pseudomacrodiplophyllum, Scapania sect. Americanae, Scapania sect. Hyperboreae, and Scapania sect. Simmonsia.

The theory of solution for quantum field functional equations is developped for a suitable testproblem of quantum mechanics. In Sect. 1 the functional formulation of the anharmonic oscillator in its spinorial representation is given, and in Sect. 2 translational equivalent functional equations are discussed. The expansion of the physical state functionals into series of basefunctionals and the ...
