Using the plastic cuticular imprint method of Sinclar and Dunn (1961), stomatal traits involving frequency, size, and, in some cases, also index and influence of some environmental factors, have been studied in 29 Canadian species of Salix (temperate) and 12 species belongings to 8 general of tropical flowering plants growing in and around the Lagos University Campus with a view to finding out if they show any definite pattern, are susceptible to environmental influences and if they can be useful for taxonomic purposes. Of the tropical species, four of the Dioscorea species and the three cultivars 'dura', 'tenera' and 'pisifera' of Elaeis guineansis are important cultivated plants. The methods of stomatal development in these plants have also been studied and reported here for the first time, along with the findings from the study of the other traits mentioned above.
