Taxonomic Revision and Numerical Analysis of Hibiscus L. in Egypt

The development of agriculture over the last decades has resulted in a continuous change of the natural vegetation of Egypt. Several species widely cultivated as economic crops or ornamentals. Numbers of species which escaped from cultivation and naturalized in naturals habitats are increasing. It i...

description	The development of agriculture over the last decades has resulted in a continuous change of the natural vegetation of Egypt. Several species widely cultivated as economic crops or ornamentals. Numbers of species which escaped from cultivation and naturalized in naturals habitats are increasing. It is necessary to study the changes in the natural vegetation and traces the new species.
