Pierrebraunia is a genus of flowering plant in the cactus family Cactaceae. Its only species is Pierrebraunia bahiensis, endemic to Brazil. Its natural habitat is rocky areas.
==Description== Pierrebraunia bahiensis is a solitary cactus characterized by its green to gray-green shoots, which are spherical to cylindrical in shape. These shoots can grow up to 1.1 meters tall and have a diameter of 8 centimeters. They feature 9 to 14 rounded vertical ribs. Initially, the round areoles are covered with cream-colored wool, but they eventually become bare. The spines are finely needle-shaped and somewhat flexible, varying in color from yellowish to reddish, eventually turning gray. Each shoot has a central spine that can be up to 3 centimeters long, along with 6 to 11 radial spines that can reach up to 1.6 centimeters long, with older areoles containing as many as 23 spines that are either erect or spreading.
