Discussion:?R. Friderici Augusti Sehomb., Die Eapatea Friderici Augusti und Saxo-Fridericia regalis, E. H. Schomburgk, Braunscbweig, 1845. Rapatea Friderici Augusti Sehomb. may well be the same as our R. steyermarkii, but so far as I a m aware, none of Schomburgk's specimens are now extant, and his brief descriptions and drawings are not adequate for acceptable placement. The indefinite indication of locality, "Wacht in dichten Waldungen des britischen Guiana," does not lend geographic support that an otherwise more definite geographical designation would have accomplished. Until more effective evidence is at hand, it is best to let the name R. Friderici Augusti rest as a nomen ambiguum.
