Cenostigma pluviosum

Cenostigma pluviosum, formerly Caesalpinia pluviosa and also known under the synonym Poincianella pluviosa, is a medium to large tree in the family Fabaceae, native to Brazil where it is widely known as sibipiruna. It is a deciduous to semi-deciduous tree reaching up to about fifteen to twenty metres, with a broad, rounded, spreading crown and fissured greyish bark. The leaves are bipinnate and fern-like, divided into numerous small leaflets, giving the canopy a fine, feathery texture. In flowering it produces abundant, showy panicles of bright yellow, faintly red-spotted flowers that cover the crown and resemble those of its relative the flamboyant. The fruit is a flattened, woody pod that splits to release the seeds. Fast-growing, ornamental and tolerant of urban conditions, sibipiruna is one of the most popular street and shade trees in Brazil and is widely planted along avenues and in parks and squares.
