Trichocereinae is a subtribe of cactus that are particular to South America.[1] There are 28 recognized genera in this subtribe.

Description

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 flower cup is scaled or covered with hair.

The fruits are fleshy to berry-like and sometimes burst open lengthwise. They contain small to medium-sized seeds that vary in shape. Hilum and micropyle of seeds are fused to united. Appendages are usually absent. A strophic is present in some.[2]

Genera

The composition of the subtribes of the tribe Cereeae varies. The list below is based on genera accepted by Plants of the World Online as of October 2023[3] and placed in subtribe Trichocereinae by Lendel in 2013. Reicheocactus (listed here) was not included in Lendel's analysis, and was described as basal to the subtribe.[1]
