Abstract

Structural Variation of Stomata in Some Dicotyledonous Trees

Obembe, O. A.

24 tree taxa distributed in 13 orders and 14 families were documented on the nature and structure of stomata. The epidermis cells are generally arched has found in 15 taxa, the remaining 9 taxa with wavy epidermal cells. Anomocytic, anisocytic, paracytic and mixed stomata complex with preponderance of solely anomocytic type in 13 taxa were observed. Stomata size ranging from 10.08μm±0.16 x 7.06μm±0.10 in Cleistanthus polystachyus to 29.57μm±0.24 x 16.80μm± 0.18 in Barteria nigritiana and stomata index values varying from 1.06% in Canarium schweinfurthii to 17.35% in Carpolobia lutea were recorded in this study.
