The receptacle includes a substantially cylindrical sidewall, an upper, radially outwardly extending collar, a bottom wall including an integrally formed, upwardly extending pointed projection for engaging the bottom of the bole of a Christmas tree, a plurality of circumferentially spaced, radially extending, vertical ribs integrally formed with the sidewall, at least one of the ribs having a radially outwardly extending convex portion extending from below the upper collar to the bottom of the sidewall including a plurality of teeth extending along at least a portion of the circumference of the outwardly extending convex portion. The receptacle is adapted to a base including a truncated, substantially hemispherical interior sidewall for receiving the receptacle, the sidewall having upper and lower edges.
