The present paper deals with epidermal structure and development of stomata in 14 species of Verbenaceae. The epidermal cells are either polygonal, isodiametric, or elongated in various directions, and irregularly arranged. The anticlinal walls are thick, mostly sinuous, occasionally arched or straight. The surface of the cuticle shows parallel, rarely corrugated, striations. Some 12 types of eglandular and glandular trichomes, and foliar nectaries are noticed. The mature stomata are diacytic, anisocytic, paracytic, with a single subsidiary cell, anomocytic and perigenous. The development of anomocytic stomata is perigenous, while that of others is mesogenous or syndetocheilic type. Abnormalities noticed here include contiguous stomata, stomata with a single guard cell, and aborted guard cells.

ISSN 0107-055X.Hipfage sericea is shown to possess both lipophilic glands and extrafloral nectaries. Both types of glands develop from a group of initials and show similarities in organisation of tissue systems and secretion. The nature of the secretory substances is however different. The occurrence and function of the glands are discussed.
