Abstract

The new genus Adelphacme (Loganiaceae) is here described. Adelphacme is placed in Loganieae and is distinguished from all other genera in Loganiaceae by the following unique combination of characters: stipules reduced to a persistent, membranous, interfoliar sheath; 5-merous calyx, corolla and androecium; calyx with indistinct tube; corolla glabrous or papillose with valvate aestivation; ovary semi-inferior and capsule two-horned (mitre-shaped) with styles persistent and apically united. The new combination Adelphacme minima (B.J.Conn) K.L.Gibbons, B.J.Conn & M.J.Henwood is here made. A key to the seven genera of Loganieae, recognised here, is provided. The key is modified to include all Australian genera of the family Loganiaceae.
