POWO shows distribution of species on Maps, which can be very misleading
for India.
Just to give an example, Dicliptera nasikensis is distributed in Nasik
district of Maharashtra only as per Catalogue of Life
<https://www.catalogueoflife.org/col/details/species/id/d4150c36cdc51f36cc0ceb7d56bd60ed>
and Flora of Peninsular India
<http://flora-peninsula-indica.ces.iisc.ac.in/herbsheet.php?id=102&cat=7>.
However, if you see it in POWO
<http://www.plantsoftheworldonline.org/taxon/urn:lsid:ipni.org:names:930319-1>,
its map will show as if it is distributed all over India except for Assam
and Himalayas. On clicking Full Distribution Listing under it, it says
Native to India.
As per my experience with it, it has divided India into four regions- *India,
Assam, West Himalaya *and* East Himalaya. *
So it is found in Nasik or Maharashtra only, it will show the area as shown
at POWO
<http://www.plantsoftheworldonline.org/taxon/urn:lsid:ipni.org:names:930319-1>
and
similarly for other three regions.
So beware- don't think it is distributed all over India and be careful.
