The flowers are inconspicuous, yellowish green, without petals, produced on slender catkins 10–15 cm (3.9–5.9 in) long; each flower is 1–2 mm (0.039–0.079 in) diameter. The fruit is a follicle 2–5 mm (0.079–0.197 in) diameter, containing 4–6 seeds.
Tetracentron and Trochodendron share the very unusual feature of lacking vessel elements in the wood, something not typical in angiosperms. This has long been considered a very primitive character, resulting in the classification of these two genera in a basal position in the angiosperms; however, molecular phylogenetics research by the Angiosperm Phylogeny Group and others has shown that these two genera are not basal angiosperms, but related basal eudicots.[2][3] This suggests that the absence of vessel elements in this group is a secondarily evolved character, not a primitive one.
