Contributions to the taxonomy of the genus Anticharis (Scrophulariaceae) especially in Namibia and Angola
A taxonomic overview of the genus Anticharis (Scrophulariaceae) especially in Namibia and Angola is presented. Three new species are described, viz. A. namibensis B. Nord., A. kaokoensis B. Nord. and A. angolensis B. Nord. A key to the Anticharis species of Namibia and Angola is presented. Some aspects of phytogeography, molecular phylogeny and photosynthetic pathways (C3-C4) are briefly discus...

متن کاملMorphology, Structure, and Ontogeny of Trichomes of the Grape Genus (Vitis, Vitaceae)
Trichomes are widely distributed on surfaces of different organs in the grape genus Vitis and are of taxonomic utility. To explore the morphology, structure and ontogeny of Vitis trichomes, we investigated the diversity and distribution of trichomes in 34 species of Vitis. Two main types of trichomes in Vitis are documented: non-glandular and glandular. Within non-glandular trichomes, ribbon an...
متن کاملPhylogenetic analysis of the grape family (Vitaceae) based on three chloroplast markers.
Seventy-nine species representing 12 genera of Vitaceae were sequenced for the trnL-F spacer, 37 of which were subsequently sequenced for the atpB-rbcL spacer and the rps16 intron. Phylogenetic analysis of the combined data provided a fairly robust phylogeny for Vitaceae. Cayratia, Tetrastigma, and Cyphostemma form a clade. Cyphostemma and Tetrastigma are each monophyletic, and Cayratia may be ...
متن کاملX-rays and virtual taphonomy resolve the first Cissus (Vitaceae) macrofossils from Africa as early-diverging members of the genus.
PREMISE OF THE STUDY Fossilized seeds similar to Cissus (Vitaceae) have been recognized from the Miocene of Kenya, though some were previously assigned to the Menispermaceae. We undertook a comparative survey of extant African Cissus seeds to identify the fossils and consider their implications for the evolution and biogeography of Cissus and for African early Miocene paleoenvironments. METHO...
