Abstract
The Eriocaulaceae floristic surveys are concentrated in the Espinhaço Range, the family main center of diversity. This manuscript aimed to survey the Eriocaulaceae from the Itatiaia National Park, increasing the knowledge of the family in the Mantiqueira Range, a relevant Eriocaulaceae center diversity in Brazil. Based on field expeditions and herbarium analysis, four genera and nine species are recorded, being seven of them endemic to the Mantiqueira Range. All species are terrestrial and restricted to the open formations of the high parts of the park, except Eriocaulon majusculum, which occurs in the high altitude swamps. The manuscript contains an identification key for the species, along with descriptions, comments, and photos.
