This species belongs to a group of species that have unifoliate leaves, large fruits and navicular endocarp, in which B. ephemeropetala is distinguished by large and thin stipules, leafy inflorescence and the presence of a petal whorl. For the first time, the presence of petals is recorded in Brunellia, a genus previously considered apetalous.enOpenAccessBrunelliaParque Nacional LlanganatesOxalidalesEudicotsBrunelliaParque Nacional LlanganatesOxalidalesEudicots
