Diversity of Croton (Euphorbiaceae) in the Itatiaia National Park, Brazil.

In this work, we provide a taxonomic treatment of Croton species from Itatiaia National Park - INP. The taxonomic study was based on herbarium collections, besides fieldwork to understand the morphological variability of the species. We have recorded seven species of Croton at the INP: C. alchorneicarpus, C. campanulatus, C. dichrous, C. floribundus, C. lundianus, C. organensis and C. vulnerarius, of which two are endemic of the Montane Ombrophilous Forests of Serra da Mantiqueira - C. alchorneicarpus and C. campanulatus.
