a genus of South American plants of the family Nyctaginaceae. Plants of this genus are low trees or more often shrubs—creeping, climbing, or clinging (lianas). The leaves alternate and have entire edges. The blossoms are small and profuse and are enclosed in broad, bright covering leaves (bracts), which determine the ornamental value of a bougainvillea. There are approximately 15 species. Two Brazilian species are mainly cultivated: bald bougainvillea (B. glabra)and remarkable bougainvillea (B. spectabilis). These multiply readily by means of cuttings and grow quickly. In the USSR bougainvillea is grown in the south in gardens and in the north in greenhouses.
