Check List of the Flora of Barakat Area (Gazira State) Sudan

Abstract

Here we present results of a study of floristic composition, carried out at the Barakat Area, Gazira State, Sudan. Plant specimens were collected randomly from different habitat during two field surveys. Samples were prepared and deposited in the Herbarium of Faculty of Science, University of Khartoum. We identified 127 species of angiosperm belonging to 43 botanical families. From these, 110 species were dicotyledons from 36 families; with Fabaceae, Euphorbiaceae, Mimosaceae, Convolvulaceae and Caesalpinaceae as the most richest-in- species families. Regarding the monocotyledons, there were found 17 plant species belonging to 7 families with Poaceae and Cyperaceae as the most representitive families. The less frequent families were: Polygonaceae, Aristolochiaceae, Vitaceae, Cleomaceae and Commelinaceae. Parasitic plant belonging to the families Loranthaceae and Scrophulariaceae were also recorded. In summary the flora consisted of 26 trees, 15 shrubs, 81 herbs and 5 climbers. Euphorbia was the most common genus with 4 species followed by Acacia with 3 species. The cultivated species represented 21.3% of the total flora, while the indigenous flora represented 78.7%. The vegetation of Barakat area can be described as dominated by: Acacia nubica Benth., Ziziphus spina-christi (L). Willd, Calotropis procera (Aiton) R.Br., Acacia nilotica (L.) Willd.exDelile. This study will contributes positively to regional florestic knowledge of the Sudan and stimulate further studies on the flora of Sudan.
