In the Crassula alpestris subsp. massonii inflorescence in picture the leaf or bract that lacks a flower cluster curves up. Its fleshy blade is rough, possibly from desiccation. Its margins are rolled under and its tip is pointed. The leaves are forced to spread when they subtend the stalks of flower clusters.
The main stem and cluster stalks are pinkish, faintly translucent and smooth. Individual flower stalks are short, smoothly continuing into the fleshy sepals around the corolla base.
The corolla disappears when flowering is done, the calyx persists (Frandsen, 2017; Manning and Goldblatt, 1997; iNaturalist).
