See text Trichocereinae is a subtribe of cactus that are particular to South America.

Arborescent to shrubby, Trichocereinae normally form unsegmented, spherical to columnar stems that are usually ribbed, tuberculate, or ribbed-warty.

The small to fairly large, regular or bilaterally symmetrical flowers appear laterally or below the apex and open day or night.

The list below is based on genera accepted by Plants of the World Online as of December 2024[update].

Reicheocactus (listed here) was not included in Lendel's analysis, and was described as basal to the subtribe.
