Over the last few years, the use of online scientific networks has increased exponentially. This book, therefore, provides an easy way to identify species of the families Capparaceae and Combretaceae at different stages of growth in Kordofan States. Growth indicators were seedling height, leaf length and width and petiole length (cm). A taxonomic Key was constructed to ease the identification of the species of the families Capparaceae and Combretaceae. This taxonomic key is simple and dichotomous in nature based on the significant measurable characters in seedling, sapling and adult stages in the field, in addition to the observed characters that included leaf shape, arrangement and color and fruit shapes. It was concluded the use of vegetative characters that can be practically important to differentiate between the species in the absence of fruits and flowers. This kinds of book is directed to the benefit of students and researcher in the field of botany, basic sciences and forest owners.
