Subspecies
Arthrocereus melanurus grows basally branched with multiple shoots that are up to a meter or more long. The shoots are divided at short intervals, with the individual segments being 10 to 40 cm (3.9 to 15.7 in) long and having a diameter of 2.5 to 3.5 cm (0.98 to 1.38 in). The 9 to 19 low ribs are 2 to 3 mm (0.079 to 0.118 in) high. There are numerous, unequally long, golden yellow to white thorns. The up to 15 strong upper marginal and central spines are brown.
