Studies on Datura Leichhardtii Muell. Ex Benth.

Abstract

Abstract Datura leichhardtii is readily distinguished from other species of the genus by its general morphology. Although similar to that of D. stramonium, the microscopy of the leaf differs in the length of the clothing trichomes and often in the form of the calcium oxalate crystals; it may be distinguished from other members of the Section Dutra, with the exception of D. metel, by the form and abundance of trichomes. D. leichhardtii differs from D. metel in possessing on the lamina of the leaf, glandular trichomes with a uniseriate stalk and a single-celled head. The values for palisade ratio and stomatal index are within the same range as those of allied species.
