Brasiliopuntia brasiliensis shows thin, upright, tree-like, slightly shrunken cladodes on a central cylindrical trunk reaches a height of 20 meters (or more); the tallest member of the Opuntia subfamily. The intermediate segments are cylindrical and 20 to 100 centimeters long. The leaves are bright green. The light to dark green end segments are rhomboid to ovoid, of unequal shape, narrow at the base and produce leaf-like shoots or flax sprouts. The fleshy, light green leaves are small and soon fall off. The areoles have white hairs and later develop glochids.Its white areoles bear one or two small brown upright spines. The 1 to 3 spines, which may also be missing, are thin, reddish and up to 15 millimeters long. Its light brown flowers appear only on adult plants. The yellow flowers appear near the tip or terminally on the thin-fleshed segments or from the pericarpel of old flowers, open during the day and are up to 6 centimeters long. There are hair-like staminodes between the perianth and the stamens.[3]

 

The spherical to pear-shaped to elongated, fleshy fruits are yellow, orange-red, red or purple, have a diameter of 3 to 4 centimeters and bear striking tufts of dark brown glochids. They contain 1 to 5, very large (6.5 to 10 millimeters), thick, disc-like, laterally compressed, woolly seeds. [4]
