ABSTRACT

The macro-and micromorphological characters of the leaf, stem, root and inflorescence of Bougainvillea 'Scarlett O'Hara' are presented with the aim of finding their diagnostic characters by which the plant can be easily identified in both the entire and powdered forms. The fascinating thing during the current research is the presence of bulbous trichomres, raphide crystals of calcium oxalate and pink-purple trichomes containing betalains content protrude from the tubular perianth, from the epidermal cells of leaves and from the bracts.

Keywords: Bougainvillea, Nyctaginaceae; leaf, stem, root, inflorescence.
