Dear Dineshji, I think the plant is M. incana as the infl is interrupted throughout. Indeed I treat the incana and royleana as vars. of M. longifolia. I am providing key here for clarification.
1a. Spikes slender, interrupted throughout; calyx 1 / 1.5 mm long, teeth less than half the length of the tube M. incana b. Spikes relatively stouter, uninterrupted or interrupted only at base; calyx 1.5 – 2.5 mm long, teeth more than half the length to as long as the tube 2 2a. Leaves sessile or nearly so; spikes compact rarely interrupted at base M. longifolia b. Leaves petiolate; spikes usually interrupted at base M. royleana Sampath KumarDR. V.
