Abstract

Lina Ahmed Hassaballa Ahmed and Asaad Alsiddig Ahmed Mohammed

This work is an attempt to make a comprehensive systematic study on the genus Datura at Shambat area, Khartoum State. It includes a brief description on climate, geology and topography of the study area. Three species of Datura were studied, namely: Datura tatula, D. stramonium and D. innoxia. The systematic interrelationships between these species were determined using morphological, hitological, cytological and pollen grains characters. Botanical names, synonyms and vernacular English and Arabic names have been presented. The study revealed that D. tatula is not a distinct species, but rather a variety of the species D. stramonium. The findings of this study have been illustrated using plates. The cytology of this genus needs more elaborate and advance techniques. In this respect the authors recommend the use of electron microscopy scanning to have a better view of chromosomes. It seems that there is a critical stage for identifying the various nuclear divisions and consequently chromosomal characterization.
