Summary

The present investigation describes the epidermal structure and development of stomata in 24 genera and 42 species of the Gramineae.

The mature stomata are typically paracytic with two lateral subsidiary cells placed parallel to the pore. Rarely the subsidiary cells are absent. The ontogeny of paracytic stomata is through only one mitotic division of the GMC and is haplocheilic or perigenous from organ to organ. The development of the stomata from initiation to maturity is studied through its successive stages.

Superimposed twin stomata are seen. Unicellular, bicellular trichomes and calcium oxalate crystals are noticed. The epidermal cells are mostly elongated, arranged in vertical rows and have straight or sinuous radial walls.
