 Bracts are modified leaf especially associated with a reproductive structure  such as a flower. The bracts of Bougainvillea are thin and papery and surround the tiny true flower.
 <br/>
 Each bract has a central vein with several veinlets.However they do not undergo the process of photosynthesis. The bracts too show reticulate venation.
