24. Croton muellerianus Lima (2008a: 124) View in CoL .
Type: — BRAZIL. Paraná: Campina Grande do Sul, Pico Caratuva , 16 April 2004, L.R. Lima, J.M. Silva & O.S. Ribas 358 (holotype SPF 161251 !; isotypes MBM, SP, WIS) (Illustration available in Lima & Pirani 2008b: 218).
This shrub can be recognized by its densely branched habit, leaves that are broadly elliptic or broadly ovate, and strongly discolorous, with glabrous adaxial surface and golden lepidote abaxial surface. The species is morphologically similar to C. splendidus , which can also be found in the same habitat. They can be distinguished by the presence of trichomes on the adaxial leaf surface and styles (glabrous and subentire lepidote trichomes, respectively, in C. muellerianus vs. stellate trichomes and glabrous, respectively, in C. splendidus ). The species belongs to section Lamprocroton subsect. Lamprocroton ( van Ee & Berry 2011) .
Distribution and habitat:— It is apparently endemic to Paraná, occurring in the municipalities of Antonina, Campina Grande do Sul and Morretes ( Lima & Pirani 2008a, Lima & Pirani 2008 b, Caruzo et al. 2020). It grows in open vegetation (‘campo de altitude’) or edges of cloud forest, between 1000 and 2600 m of elevation ( Fig. 12 View FIGURE 12 ).
Phenology:— Flowering from January, February, May, July, September to November, and fruiting from January, September and October.
