[3] Mirabella albicaulis grows as a shrub, with only slightly branched, initially upright, later overhanging and spreading to climbing shoots.

The elongated, bluish-white, four-edged shoots have a diameter of 1 to 3 centimeters.

The two to six unequal, needle-like spines are brown, swollen at their base and up to 2 centimeters long.

Mirabella albicaulis is distributed in the Brazilian state of Bahia.

The first description as Acanthocereus albicaulis was published in 1920 by Nathaniel Lord Britton and Joseph Nelson Rose.
