34. Croton subvillosus Müller Argoviensis (1873: 168) .

Lectotype (designated by Sodré et al. 2017): — BRAZIL. Goiás: “prope Gamelleira ”, s.d., J.B.E. Pohl 1617 [catalogue number 2164] ( W 0051217 !; isolectotypes G 00434673!, M 0089120!, K 000186135!, K 000186136!) (Illustration available in Sodré et al. 2022: 27)

Croton subvillosus is a subshrub with xylopodium, indument hirsute (ferruginous or yellowish), and generally with congested inflorescences. Sodré et al. (2022) indicated that the leaves of this species are subsessile, however the collections J. Lindeman & H. Haas 2743 and G. Hatschbach 32900, cited in their work, have conspicuously petiolate leaves (petiole ca. 1 cm long). Croton subvillosus is morphologically similar to C. grandivelus (see comments under C. grandivelus ). The species belongs to sect. Adenophylli subsect. Velamea .

Distribution and habitat:— It occurs in Bolivia, Brazil (DF, GO, MA, MG, MS, MT, PR, TO), and Paraguay ( Sodré et al. 2022). Subshrubs from cerrado, between 700 and 800 m elevation in Paraná ( Fig. 18 ).

Phenology:— Flowering from August to December, and fruiting from November to February.
