ANATOMICAL STUDY TO BRACTS EPIDERMIS OF SOME BOUGAINVILLEA GLABRA VARITY IN IRAQ

The Anatomical characters of bracts epidermis studied to seven Varity (Bougainvillea glabra var. bluish violet, B. glabra var. red, B. glabra var. yellow, B. glabra var. Bold pink, B. glabra var. Bold red, B. glabra var. white, B. glabra var. orange) belong to species Bougainvillea glabra from the family Nyctaginaceae and many characters of the bracts epidermis was useful to separate between the Varity, especially the qualitative and quantitative characters of long cells, stomata, microhairs, and macrohairs, besides, crystals Bundles. The mentioned cells varied in length, width, number of stomata, the number of Abaxial epidermises and the Adaxial epidermis, their lengths, the number of hairs, their length, and the number of hair-forming cells, which produced many important characteristics for the identification and diagnosis of the variety of Bougainvillea. So the aim of the study was to a knowledge the anatomical characters of bracts epidermis for the studied varity and use these characters to separate between those varity taxonomically
