Type: BRAZIL. Rio de Janeiro: June 1767, P. Commerson s.n. (holotype P 00382045!; isotypes P 00634800!, P 00634801!). (Fig. 19, E–G)

Croton triqueter is a shrub with congested inflorescences, 11 stamens, and unequal, deeply laciniate pistillate sepals. These characters are also present in C. didrichsenii, however, both species can be distinguished by vegetative structures and habitat (comments under C. didrichsenii). The species is the type of section Julocroton.

Distribution and habitat:— It is a widely distributed species from Mexico to Argentina., In Brazil it is also widely distributed (AL, BA, CE, ES, GO, MA, MG, MS, PA, PE, PR, RJ, RN, RS, SC, SP, SE) (Cordeiro 1990, Caruzo et al. 2020), where it grows in edges and glades of forests, riverbanks, disturbed areas, and ‘lajedos’, between 170 and 1150 m elevation (Fig. 20).

Phenology:— Flowering and fruiting throughout the year, except in July.
