8F1D87F3C12E3E5FFCFAFB22FD2FFCE6.taxon	discussion	Notes. – Mitracarpus federalensis is characterized by the ventral face of the seeds having an X-shaped groove and the dorsal face lacking a depression. Given that the species does not possess seeds with a cruciform dorsal depression (like as M. baturitensis Sucre or M. frigidus (Roem. & Schult.) K. Schum.) nor semicircular dorsal depressions (like as M. longicalyx E. B. Souza & M. F. Sales), it is clearly related to M. eitenii E. B. Souza & E. L. Cabral. However, it differs from that species by its habit, the size and development of the inflorescence and the size and indumentum of the flowers and seed surface.	en	Cabral, Elsa L., Sobrado, Sandra V., Souza, Elnatan Bezerra de (2013): Three new species of Mitracarpus Zucc.
