Abstract

Leaf epidermal structure of 30 trees distributed in 17 dicotyledenous families was studied.

Interspecific variation in cell wall pattern was observed in the two species of Macaranga covered in this study. The cells were straight-walled in M. barteri but sinuously-walled in M. monandra. In addition to this variation, peltate hairs were observed in M. barteri.

The two species also varied in their stomatal features. Alchornea was another species which showed interspecific variation in epidermal and stomatal features. Stellate hairs were observed in A. cordifolia but were absent in A. laxiflora.

Mature stomata were paracytic in A. cordifolia but in A. laxiflora they were anomocytic. Differences in stomatal size and frequency were also observed in the two species. Contiguous stomata were reported here for Avicennia africana, Mitragyna inermis and Pterygota macrocarpa.
