description
The species of the genus Brasilicereus grow shrubby with upright, sometimes crooked shoots that rarely branch and reach a height of between 1 and 4 meters. The slender shoots have a diameter of up to 2.5 centimeters. The 3 to 5 ribs are flat or narrow. The whitish to grayish-brown thorns arising from the areoles covered with gray or white wool are needle-like and brittle. The 1 to 4 central spines are up to 4 centimeters long, the 10 to 18 radial spines 0.5 to 1.5 centimeters long.
The short-tube to bell-shaped flowers open at night. Your flower cup and the flower tube are covered with conspicuously fleshy scales, the areoles are bare.
The dull green to purple, non-tearing fruits are spherical to pear-shaped and have a persistent flower remnant.

The genus includes the two species:
- Brasilicereus markgrafii Backeb. & Full
- Brasilicereus phaeacanthus (Cucumber) Backeb.
A synonym of the genus is Bragaia Esteves, Hofacker & PJBraun (2009). Their only species Bragaia estevesii Hofacker & PJBraun (2009) was placed in 2011 by Nigel Paul Taylor and Marlon Machado as Brasilicereus estevesii (Hofacker & PJBraun) NPTaylor & M.Machado (2011) in the genus Brasilicereus . Joël Lodé recognizes the genre as independent.
