Description
Arborescent to shrubby, Trichocereeae 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.
