Bougainvillea spectabilis. TRINITARIA. 
A showy climbing shrub, belonging to the family Nyctaginaceae. Its striking 
appearance is due to the large purplish pink bracts, the true flowers being yellow- 
ish and quite small. The color is extremely conspicuous, and to some it appears 
painfully ‘‘loud.’? In Porto Rico a quite different plant, Antigonum leptopus, 
producing similar large masses of brilliant color, though of a more pleasing shade 
of pink, has been mistaken for Bougainvillea by travelers and popular writers.
