Euphorbia tithymaloides (syn. Pedilanthus tithymaloides) · Devil's backbone / Slipper plant

The plant shows thick, succulent, jointed stems with distinct nodal segments and narrow, lance-shaped leaves borne singly and somewhat alternately along the stem, giving a slightly zig-zag growth pattern typical of the Pedilanthus/Euphorbia tithymaloides group. This differs from the previously ruled-out Euphorbia tirucalli (which lacks persistent leaves and has thin cylindrical stems), E. neriifolia (which has more oleander-like, thicker leaves and spine pairs), and Synadenium grantii (which has broader, fleshy obovate leaves and a shrubbier, less jointed stem). However, without a visible flower (the small cyathia of Euphorbia tithymaloides are distinctive and slipper-shaped) or a clear close-up of leaf attachment/latex color, I can't rule out other succulent Euphorbiaceae or even Senecio/Kleinia species with similar segmented, leafy stems. A photo of the growing tip, any bract/flower structure, or a cut stem showing latex color would help confirm the genus and species definitively.
