Contribution to the flora of Um Rimmitta area, White Nile State, Sudan

The study deals with the ecology and taxonomy of the vegetation of Um Rimmitta area, Central Sudan. Taxonomic studies included collection, preparation, identification and classification of plant species in the study area. A total of 85 plant species were identified belonging o 30 families, represent the flora of the study area. From the identified species of the present study, (42) species were found to have medicinal values, and these represented (49.4%), of the total plant species of the study area. Moreover, a check-list of endangered, extinct and famine food plants has been provided. The study shown that during the drought spells in 1975, 1980, some of the plant species at the study area were lost. Also the study found that some plant species supported that locals during the period s of drought and bridged the gap in food supplies. The present study revealed that the soil moisture content was relatively low at the study area. The chemical analysis of the soil shown that there were no significant differences between sites in the study area with respect to soil elements. However, there were significant different between the sites in their pH values.
