Abstract: A Christmas tree stand has a base having a jaw assembly with a bottom for slidably engaging a tree trunk and a bar, above the bottom of the jaw assembly, for forcibly clamping the trunk laterally between the bar and jaw assembly. The bar member is preferably relatively stiff but resiliently bendable, and pivotally attached to the base so as to be movable selectively toward or away from the tree trunk laterally. The bar is lockable in variable positions relative to the base in tight engagement with trunks of differing diameters. After the bar is locked, the tree is easily straightened by grasping an upper portion of the trunk and moving it laterally, causing the bottom of the trunk to slide laterally across the bottom of the jaw assembly while the bar acts as a fulcrum about which the trunk pivots.
