Wendlandia pendula (Wall.) DC. 
Nepali Names :  पारेधयाँरो Paaredhayaro/ रानीधयाँरो Raneedhayaro 

Please, may I ask a question? 
Of the 8 Wendlandia that occur in Nepal, how was it decided that this is the W. pendula and not one of the others?
Was there something visible in the several photos that helped make the decision? Thank you.

W. appendiculata
W. coriacea
W. grandis
W. exserta
W. pendula
W. proxima
W  scabra
W. tinctora 

I checked all one by one listed in Nepal. I guess the description, image in the net matching to it not other.

Thank you for the explanation. I admire your diligence and will strive to be more thorough.
