Vein-endings, free vein-endings, isolated vein-endings and isolated tracheids are discussed and distinguished. Vein-endings whether simple or branched may or may not terminate in terminal tracheids. The nature of vein-endings is uniseriate in

The structure and ontogeny of normal and abnormal stomata in the seedlings of 16 species of the Cruciferae have been presented. The mature stomata are anomocytic, paracytic, anisocytic, helicocytic and with a single subsidiary cell. The ontogeny of the anisocytic, paracytic, helicocytic and stoma with a single subsidiary cell conforms to the syndetocheilic or mesogenous, while that of anomocytic to haplocheilic or perigenous type. Several types of aberrant stomatal formations such as: single guard cell; contiguoas single-guard cells; contiguous stomatal; degeneration of guard cell/s; persistert stomatal cell; amitotic division of guard mother cell nucleus followed by pore formation; stoma with double pores; binucleate guard cell; division of guard cell; incomplete stoma with unequal guard cells; cytoplasmic connection; ring-shaped division of guard mother cell and uncommon wall thickening have been noticed. Aberrant stomatal developments are naturally occurring and not induced.

Leaf architecture including venation pattern has been studied in 19 genera and 29 species of the Apocynaceae. The leaves are simple, alternate, opposite or whorled with entire margin and a simple midrib. The major venation pattern conforms to pinnate camptodromous type with festooned brochidodromous secondaries. The qualitative and quantitative features are charted. The leaf size, areole size, number of vein endings entering the areoles and number of vein terminations entering the areoles vary from species to species even within the same species. The highest degree of vein order is observed up to 7°. Isolated tracheids, isolated vein endings, isolated free vein endings and tracheoidal elements are noticed. Bundle sheath cells ensheaths all category of veins.

Cotyledonary blade is symmetrical in all the species of Asteraceae. Morphological features such as base, apex and margin vary from species to species. Venation pattern conforms to pinnate craspedodromous, pinnate camptodromous and acrodromous type. Higher order veins noticed are up to 5°. Primary vein is either stout massive, moderate or weak. The thickness of the veins gradually decreases from primary to higher order veins. Marginal ultimate venation is either incomplete, looped or fimbriate. Areoles are absent in

In some Apocynaceae a group of 10–15 resin glands is present as finger-like projections on the adaxial side of the proximal end of the petioles and sepals or petals. They originate from a group of epidermal and sub-epidermal cells. At maturity the glands are differentiated into a short stalk and a clavate head. The latter is composed of epidermal secretory cells and sub-epidermal parenchyma. Structurally and ontogenetically the resin glands resemble extrafloral nectaries and the standard colleters of the Rubiaceae. However, histochemical tests for lipophilic substances revealed that these glands secrete resin. The pale yellow, viscous secretion is released by cuticular bursting and covers the tender shoot apices and developing buds. The position and the secretory activity of the resin glands in relation to their function is discussed.
