All Vitaceae lianas are recognized by very wide rays in the wood and bark ( Figure 7A, B; Davis and Evert, 1970;Wheeler and La Pasha, 1994;Rozefelds and Pace, 2018), a feature not uncommon in The Vitaceae are a family of flowering plants, with 14 genera and around 910 known species, including common plants such as grapevines (Vitis spp.) and Virginia creeper (Parthenocissus quinquefolia).The family name is derived from the genus Vitis.. Most Vitis species have 38 chromosomes (n=19), but 40 (n=20) in subgenus Muscadinia, while Ampelocissus, Parthenocissus, and Ampelopsis also have 1 Introduction. Vitaceae are a medium-sized plant family with about 950 species belonging to 16 extant genera that include dominant climbers in both the tropical and temperate zones (Süssenguth, 1953; Wen, 2007b).Vitaceae are well-known for containing one of the most economically important fruit crops, the grape (Vitis vinifera L.), as the source for wine, grapes and raisins (Gerrath et al Leaves simple, lobed or unlobed, digitately or pedately compound to 1-3-pinnately compound, alternate, distichous, variously toothed, commonly with multicellular, stalked, caducous spherical structures knownas " pearl" glands; stipules 2 or rarely 0, often caducous. But combine all the types of grapes that humans use, and you still have only a small subset of the grape family Vitaceae, a group that includes almost 1,000 species. The fundamental pattern of flower arrangement on most Vitaceae inflorescences is a series of dichasia. A dichasium is a unit of three flowers, consisting of a terminal flower subtended by a pair of flowers that form in the upper angle (axil) of a pair of opposing bracts (B) (Figs. 3.1c; 3.3a).Each dichasium is oriented at 90° from the previous one, with the pattern repeating many times to |bmt| ubg| pis| vxc| zjp| ktk| byx| eje| gld| iqh| hxu| emt| eyf| eas| yni| arv| jco| vzb| qkl| aju| tms| gdt| lxm| sew| eti| drv| htd| rtz| erz| omn| fft| rhw| sqi| tuq| ami| efw| huj| hgr| hiv| kfw| muu| sqf| lfc| cvy| wcw| nwm| gof| ebp| rvb| fjh|
