An adjustable tree stand utilizes a receptacle for receiving and securing the bole of a Christmas tree. 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. The base includes an outwardly flared, exterior sidewall, the interior and exterior sidewalls being joined at the upper portion of the base to form an annular, locking ring receiving collar, a plurality of circumferentially spaced, radial support members, the support members extending outwardly from the exterior sidewall and a plurality of circumferentially spaced support ribs extending inwardly from the lower edge of the interior sidewall. The receptacle is secured in the base with a split, outwardly biased locking ring, the locking ring being positioned inside the locking ring receiving collar. A locking lever engages the locking ring, and is selectively moveable to constrict the locking ring and engage the teeth of the receptacle to secure the receptacle in the desired angular orientation relative to the central or vertical axis of the base unit.
