This is a flower typical to the Western Ghats of India.
It is called 'सीतेची आसवॆ' in maraaThee, whose botanical name is
"Utricularia Purpurascens".
It was shot at the Kaas plateau, which is also called the
"valley of flowers" of Maharashtra. The dark purple colour
actually also emits ultraviolet radiations, which are visible to
various insects and birds, who cause pollination of these
flowers. Emitting Ultraviolet radiations is thus one of the
ways of promoting its pollination.
