Background/Objectives: Most of the species of Datura imposes a wide lacuna in our knowledge especially for proper identification and pharmacognostical studies. Anatomical structure is most likely to provide evidence concerning the interrelationships of families or in establishing the real affinities of species of uncertain taxonomic status. Methods...

Context 1
... has been a perennial controversy with regard to certain species of Datura. The floristic botanists, pharmacognostic scientists and taxonomists have contributed to their mite towards creating more controversies coupled with confusion while circumscribing the taxonomic status of D. fastuosa (Figure 1), D. innoxia and D. Metal. Most of the descriptions of these taxa have been at 'alpha level' which may not obviously help to resolve the controversy. ...
