I completely agree with Garg ji, the plant here is I. nil. The two species
are often confused but the calyx and folds colour helps in identification.
The distinctive feature is however, that base of calyx lobes has spreading
hairs in I. nil, not in I. indica where calyx is appressed pubescent. Also
the upper part of calyx lobes narrows suddenly in I nil and tip has a long
acumen. In I. indica the lobes gradually narrow to tip. Also the upper part
of calyx lobes is more or less glabrous, where as it is appressed pubescent.
And lastly, and more decisive the colour of leaves, calyx lobes is ligher
green in I. nil, whereas it is darker and greyish green. So for me it is I.
nil.
Yes Tabish ji, I would request you that you avoid having photographs
from two different persons linking to the same species. It can create
problem of identity. I had earlier pointed about photographs of Thunbergia
grandiflora. The one by Aarti Khale belongs to T. grandiflora, but one by
Dinesh Valke to T. laurifolia. Here also I strongly feel that photograph by
Pravin Kawale is I nil whereas one by Thingnam Girija is a different
species. I hope you won't my pointing this out.
