Impatiens grandis, from the Western Ghats of Tirunelveli, TN.
Very beautiful, at what altitude is this plant common in Tirunelveli hills?
I know the species only from pictures, but there were always red markings on petals.
Did you seen other plants?
@ ...: we collected this species somewhere near Kakkachi on the way to Upper Kodayar Dam, must be around 1300 m altitude.
@ ...: yes, the petals had very faint red markings. 
Thanks for this rare upload bro! Wonder why the name I. grandis. Are the flowers too big?
