Lectotype (designated by Santos et al. 2017): — BRAZIL. Minas Gerais: s.loc., 1838, P.C.D. Claussen 773 ( P 00493373 !; isolectotype P 00493372!) . Remaining syntype: — BRAZIL. Mato Grosso: s.loc., 1833, C. Gaudichaud-Beaupré 250 (P 00493374!). ( Fig. 9 View FIGURE 9 , F–J)

This shrub or small tree can be recognized by its ovate leaves with sessile acropetiolar nectary glands and pistillate petals transformed into conspicuous nectary glands. Croton gracilipes differs from C. urucurana by the length of the staminate flowers (7 mm in C. gracilipes vs. 3.5 in C. urucurana ), pistillate petals (nectary glands in C. gracilipes vs. filiform in C. urucurana ), and the columella apex (inflated and trilobed in C. gracilipes vs. inconspicuous and unlobed in C. urucurana ). It is the only species that can be also found as a small tree that possess an inflated, trilobed columella apex. It belongs to Croton sect. Adenophylli subsect. Pungentes Croizat ( van Ee & Berry 2021) .

Distribution and habitat:— It occurs in Argentina, Bolivia, Paraguay and Brazil (DF, GO, MG, MS, MT, SP, PR) ( Santos et al. 2017, Caruzo et al. 2020), growing in edges of semideciduous seasonal forest, and also in fluvial islands (northwestern Paraná state), between 350 and 900 m elevation.
