Brodriguesia santosii is a tree in the subfamily of the carob family, in the legume family. It is the only species of the genus Brodriguesia and it occurs only in eastern Brazil in the state of Bahia . The species is endangered and the population has declined sharply.
Brodriguesia santosii grows as a smaller, evergreen tree and reaches heights of about 20 meters or more. The trunk becomes up to 80 centimeters thick. The alternate and short-stalked leaves are pinnate in pairs with a few (4–6) and almost sessile, slightly leathery and ovate to elliptical leaflets . The short petioles are twisted. The leaves are up to 6.5 centimeters long, the whole, glabrous and rounded to pointed leaflets up to 6.5–8.5 centimeters. The central artery of the pinnate nerve is more or less easily protruding. There are stipules present.
The terminal or axillary inflorescences are paniculate and up to about 10 centimeters long. The four to five-fold and stalked, small flowers are hermaphroditic with a double flower envelope. There are sloping bracts on the flowers and inflorescences . The greenish-yellow calyx is four-part, the yellowish corolla is five-part, they sit on a hairy, funnel-shaped, short-stalked and green flower cup . The elliptical sepals are hairy inside and out, the more or less pointed petals, which are divided into a short nail and a larger elliptical plate , are free and hairy on the inside. The sepals and petals are arranged in roof tiles. The very long, filamentous 10 stamens are briefly fused at the base. The elongated, medium to (under constant) ovary is stalked with a very long, thin stylus with a small, capitate scar .
The flat, matt-brownish and smooth, slightly leathery, somewhat veined legumes are relatively straight and elliptical. They are up to 6.5 (13) centimeters long and up to 1.3 (6.5) centimeters wide and are somewhat speckled, as well as partly pointed. The up to 3 blackish, dull and flattened, elliptical seeds have a very small and reddish aril around the hilum , they are up to 2.5 centimeters in size.
