Abstract
In the present paper, epidermal structure and development of stomata are described in 15 species of the Polygonaceae. Epidermal cells ofPolygonum species contain druses of calcium oxalate. Parallel cuticular striations are noticed. Six types of glandular, non-glandular trichomes and extra-floral nectaries are observed. The mature stomata are anisocytic, anomocytic and paracytic. The anisocytic and paracytic stomata may be monocyclic or amphicyclic. The anomocytic stomata are incompletely monocyclic. The increase in number of subsidiary cells in anisocytic and paracytic stomata is due to the divisions of the subsidiaries. The ontogeny of anisocytic and paracytic types is syndetocheilic or mesogenous, while that of anomocytic is haplocheilic or perigenous. Twin stomata are also noticed.
