  • Discussion

    Collected in flower October to March, and in fruit in March.

    This species is distinguished from B. campestris by its habit as a small shrublet to 4 dm tall, its small elliptic, hispido-pubescent leaves, and its reduced fruit wing.

    The scarcity of fruiting collections perhaps reflects the inconspicuousness of the fruits; since the plants are small, and the fruits are also small and more or less hidden by the foliage, they are easily overlooked.

  • Distribution

    Known only from the Serra do Cipó, Minas Gerais, Brazil, growing on rocky campo in quartz sand at 1000-1300 m.
