28. Croton reitzii Smith & Downs (1959: 152) View in CoL .
Type: — BRAZIL. Santa Catarina: Canoinhas, 19 km ao oeste de Canoinhas no caminho para Porto União , 17 December 1956, L.B. Smith & R. Reitz 8590 (holotype US 2249814 !; isotypes K 000254430!, NY 00262942!, R 000200949!, UC 1079899!) . (Illustration available in Smith et al. 1988, p. 100)
Due to its congested inflorescences and dense indumentum, this shrub may resemble members of Croton sect. Julocroton , which justifies the comparison made by Smith & Downs (1959) with C. calocephalus Müller Argoviensis (1865:121) . However, C. reitzii can be distinguished from all species in section Julocroton by its leaves with basilaminar nectary glands and its inflated, trilobed columella (both characters absent in sect. Julocroton ). Collections of C. reitzii have been misidentified in some herbaria as C. lanatus , but they can be differentiated by several vegetative and reproductive characters (see under C. lanatus and Table 2 View TABLE 2 ). Croton reitzii belongs to section Adenophylli subsect. Meridionalis ( van Ee & Berry 2021) .
Distribution and habitat:— It occurs in southern (PR, RS, SC) and southeastern (SP) Brazil ( Smith et al. 1988, Caruzo et al. 2020), where it grows in borders of Araucaria forest , rarely in open vegetation, between 475 and 1155 m elevation. ( Fig. 14 View FIGURE 14 ).
Phenology:— Flowering and fruiting throughout the year, except August.
