12. Croton fulvus Mart. View in CoL in Spix & Martius (1823: 282).

Lectotype (designated by Sodré & Silva 2020):— BRAZIL. Minas Gerais: “prope Barreira , inter frutices, ad camporum margines et in vepretis”, s.d., C.F.P. von Martius Obs. 1407 ( M 0089129 !; isolectotype G 00434720!) . (Illustration available in Sodré & Silva 2020: 210)

Croton fulvus is morphologically similar to C. grandivelus , due to overlapping features (such as shrub habit, stature, presence of colleters, trichome type, and entire stipules with colleters at the base). Sodré & Silva (2020) used stem branching as a diagnostic character (much-branched stems in dichotomous or trichotomous, sometimes even in 6- furcation in C. fulvus vs. few-branched stems in simple ramifications or in dichotomies, sometimes trichotomies in C. grandivelus ), stem ornamentation (striate in C. fulvus vs. smooth in C. grandivelus ), and capsule shape and indumentum (oblong and pubescent in C. fulvus vs. globose and velutinous in C. grandivelus ). The species belongs to sect. Adenophylli subsect. Velamea ( Baillon 1864: 316) van Ee & Berry (2021: 333)

Distribution and habitat:—It occurs in Argentina, Bolivia, Brazil (BA, DF, GO, MA, MG, MS, MT, PR, SP, TO), and Paraguay ( Sodré & Silva 2020), in cerrado and “campo sujo”, between 700 and 805 m of elevation ( Fig. 6 View FIGURE 6 ).
