摘要
to continue the survey on marantaceae taxa being carried out in brazil, new taxonomic and nomenclatural proposals are made involving some species of marantaceae described and illustrated in flora fluminensis by friar jos谷 mariano da conceiˋˋo vellozo. maranta monophylla, m prolifera and m. tuberosa are circumscribed here from morphologic and phytogeographic information contained in descriptions and commentaries from vellozo%26apos;s originals, as well as from analysis of prints which were published subsequently that illustrate the species in detail. from the gathered data and the comparison with recent collections and nomenclatural types, a new combination is proposed, due to the necessity of transferring m. prolifera to the genus calathea. some calathea species commonly cited in floristic surveys at the atlantic forest are proposed as synonyms.
