Croton chaetophorus is a subshrub with pistillate sepals covered by glands (apparently colleters), except at the base, which is a useful character for its identification. Bracts are lanceolate-rhombic and, due to their morphology, they totally cover the flower buds. The species can be confused with C. serratifolius, however, the bracts and stipules of C. chaetophorus do not have glands, its leaves are ovate to ovate-lanceolate, whereas, in C. serratifolius, bracts and stipules have glands along the margin, and the leaves are elliptic to oblong. The species is a member of Croton sect. Barhamia subsect. Medea (van Ee et al. 2011).
Distribution and habitat:— It occurs in southern (PR, SC) and southeastern (MG, SP) Brazil (Smith et al. 1988, Caruzo et al. 2019). Plants grow in open vegetation (‘campos sujos’), edges of forest and, rarely, in ‘banhados’, between 980 and 1090 m elevation (Fig. 2).
Phenology:— Flowering and fruiting from October to February.
