With amended character of Creseentiacea?, and diagnoses of the genera and twenty-six species composing the group. "Dr. Seemann adopts the Tribes Tanceciece {Calyx persistens, regularise 5-merus) and Crescentiece (Calyx deciduus, irregularis — spathaceus vel bipartitus). No new genera are founded. Schlegelia and Tripin- naria are suppressed, being identical with Tancecium and Colea respectively. Periblema, DC. is excluded from the Order. The Crescentiaceae chiefly prevail in the islands of East Africa, whence further additions are probably to be received. Two species occur in Asia, ten in America.
