Abstract
Despite the recent publication of floristic treatment of Eriocaulaceae for the phanerogamic flora of the state of São Paulo, specimens of two non included species of Paepalanthus were found in herbaria. Additionally, a new species of Paepalanthus occurring in the State was recently described. We present here the description of P. glabrifolius, P. pseudotortilis, and P. sphaeroides, as well as photos and brief comments on its morphology, geographical distribution, and phenology. We also provide an updated identification key for the Paepalanthus species occurring in the state of São Paulo, which hosts now 21 species.
