Résumé
In preparation for a floristic treatment of the family Balanophoraceae for the states of Goiás and Tocantins, Brazil, two remarkable collections were found. One is here described and illustrated as a new species of Lophophytum (L. rizzoi Delprete), and the other is the first record from the state of Goiás of Lathrophytum, a genus previously known only from the Atlantic forests of the state of Rio de Janeiro.
