Thanks Gurcharan ji, for the clarifications. I have always been
uncertain about my identification of Peristrophe roxburghii at FOI -
will give a revised look. Thanks particularly for the link of the
illustration of Peristrophe roxburghiana - this is something I wanted
badly. I was not too worried about Peristrophe roxburghiana being a
cultivated plant because we found it in Nainital, where there are lot
of flora planted by the British, and garden escapes are common.
Meanwhile, does any of your pictures of Dicliptera bupleuroides show
the sepals - I believe they are supposed to be linear-lanceshaped.
