Thanks Shrikant ji for nice information

Perhaps status of E roseum vs E. pulchellum have to be investigated

All four E. capense, E roseum, E. pupurascens and E. roseum are recognised are accepted names

The shrub growing in Delhi and identified as Eranthemum nervosum (Vahl) in Flora of Delhi is now correctly known as E. pulchellum Andrews

Eranthemum nervosum Dalzell and Gibson is now correctly known as E pupurascens Wight ex Nees. 

If E. purpurascens is distinct in absence of white patches on bracts, we will have to find differences between E roseum and E. pulchellum to know our exact plant. I am uploading my photographs from Delhi

      Bracts obovate, mucronate, strigose and spikes longer than 7.5 cm....E. roseum (Vahl.) R. Br.

Bracts green

      The bracts many nerved, white ciliate on margins...E. purpurascens Nees
      The bracts few nerved, viscous hairy......................E. capens L. var. concanense (T. And. C. B. Cl.) Sant.
