| dc.description.abstract | The foliar epidermal characteristics of all West African species of the tribe Parietarieae and some taxa in the tribe Urticeae were investigated by the means of light microscopy for the purposes of easy identification and justification of recent taxonomic merging of Fleurya with Laportea. In the tribes, cell number is higher on the adaxial surface (52 to 110) than on the abaxial surface (19 to 96), stomata number varies from 31 to 42 per mm² while cell size ranged from 60.8 - 70.4 μm x 22.4 - 32.0 μm on the adaxial surface and 32.0 - 40.0 μm x 16.0 - 22.4 μm on the abaxial surface. Generally, all the species have hypostomatic leaves and anomocytic stomatal type but paracytic and anisocytic types are diagnostic for Laportea aestuans, Laportea ovalifolia, Parietaria laxiflora, and Laportea alatipes. Glandular and simple trichomes of different sizes were observed in all the taxa except in Girardinia heterophylla and L. ovalifolia. The cell shape, anticlinal wall pattern, and stomatal type which correlate to a reasonable extent have supported the amalgamation of Laportea and Fleurya. Crystal sands of calcium oxalate were found in L. ovalifolia, Girardinia condensata, and Parietaria laxiflora while peltate scales distinguished P. laxiflora from other species. The species have medicinal and economic values. An artificial indented dichotomous taxonomic key for separating the taxa is presented. | en_US |
