Brasilicereus estevesii

Bragaia estevesii typically grows as a weakly branched, upright shrub with a slightly woody base. Its green, cylindrical shoots can reach up to 4 meters long but usually stay shorter. These shoots have 10–12 blunt ribs and are sometimes covered in needle-like, yellowish-brown thorns. The flowers, which open at night and are pollinated by bats, form laterally in the upper part of the shoot. They are slender, funnel-shaped, and lightly scaled, with extrafloral nectar glands, and can be green, yellow, or red. The petals range from greenish-white to white. A noticeable feature is the strong constriction above the pericarpel. The fruit is small, spherical to slightly oval, measuring 15–19 mm long and 6–8 mm wide, with transparent pulp and no exterior spines. The helmet-shaped black seeds are relatively large at 1.5–1.8 mm.

Bragaia estevesii is found in northeast Brazil, specifically in the Caatinga region of northwestern Bahia.
