摘要

The nutlet characters in the Lamiaceae are of great taxonomic significance. Macro and micro morphology nutlets of 23taxa belonging to 12 genera of Lamiaceae from Al-Taif, Saudi Arabia have been studied for the first time by both light andscanning electron microscope. Observations revealed that nutlet color, shape, size, presence of areole are of limitedtaxonomic value. However the pericarp sculpturing are the most important diagnostic characters for differentiating thespecies through a constructed key. Three main distinct types of nutlets sculpture can be distinguished; smooth, partlysculptured and sculptured, within these types 12 subtypes are also recognized (reticulate, reticulate-foveate alveolate,granulate, rugose-scalariform, favulariate, protuberance, colliculate, ruminate, ocellate, verrucate and tuberculate). Therelationships between the studied taxa were demonstrated as a phenogram.
