the genus astragalus l. (fabaceae) is reviewed from both phyloenetic and taxonomic points of view. as the largest genus of flowering plants it has attracted many researchers, but much work remains to be done. a short taxonomic history with special focus on infrageneric classification of the genus, a list of phylogenetic studies including the applied markers and sampling strategies as well a...

In this paper new semi-empirical formulas are developed to evaluate the variation of both real and imaginary parts of soil complex permittivity with depth inside the earth's surface. Computed values using these models show good agreement with published measured values for soils of the same textures and same frequency band. Use of these models may serve to handle more accurate results especially...

The genus Gephyraulus Rübsaamen (Diptera: Cecidomyiidae) is newly recorded on Fabaceae and in Japan. tokudai Elsayed n. sp. that develops the flower buds of Caesalpinia crista L. (Fabaceae) described here as new to science. A description, illustrations, ecological features species are given. In addition, a molecular phylogenetic analysis including species, G. zewaili lycantha, each from differe...
