When you run the key, ..... ........ 4. stem woody at base, stamens 8....; 5 (if this is the case it can be L decurrens) 4. Stem herbaceous, stamens 4.... 6 (if this is the case mostly L perennis)
Here in Sathish jis pictures I think the number of stamens are 4 Hence I say it is *L. perennis* Satish ji or Mohina ji, Please clarify by using the key i Rheedea article.
