Anyr-edge-colouredn-vertex complete graphKncontains at mostrmonochromatic trees, all of different colours, whose vertex sets partition the vertex set ofKn, providedn?3r4r! (1?1/r)3(1?r)logr. This comes close to proving, for largen, a conjecture of Erdos, Gyarfas, and Pyber, which states thatr?1 trees suffice for alln.
