A typical caldelabra type species, similar to P. prolifera and considered by John Richards to be a synonym of that species, but considered distinct by other authorities. The most obvious difference is color (P. ianthina is violet where as P. prolifera is yellow) but also habit, glandular tipped bracts, distribution and seed & pollen morphology. The leaves are glandular pitted especially on the lower surface and the calyx is farinose and divided to the middle. Only found on the Singalela Ridge from Megu to Sandakphu.
