Thanks, …, for the wonderful images.

How is it different from Lepidagathis cuspidata Nees ?

Is there any observation at Lepidagathis cuspidata Nees, which may be of L. rigida ?

Yes very different than L.  Cuspidata

Any keys to differentiate the two?

I have identified it from Cooke and compared it with protologue
