The slipper spurge (Pedilanthus tithymaloides) is a small cactus-like herbaceous plant. The shoot apex has a single tunica layer and sometimes the second layer also simulates it. There is a central meristem zone whose significance could not be determined. The first bud meristem differentiates at the second node. The earliest bud meristem has a procambium but no shell zone was observed. The node is trilacunar. There are three bud traces and three prophyll traces. The single prophyll is situated at right angles to the subtending leaf.
