Ammannia auriculata

Ammannia auriculata Willd., Hort. Berol. 1: 7 1806. (syn: Ammannia aegyptiaca Willd.; Ammannia auriculata var. elata (A.Fernandes) A. Fernandes; Ammannia hyrcanica Fisch. ex Steud.; Ammannia latifolia Walp.; Ammannia longipes Wright apud Sauvalle; Nesaea transvaalica A. Fernandes);   


This species occurs throughout tropical and sub-tropical regions of the world, from south-eastern North America through central America and the Caribbean to Argentina, from Egypt to south Africa and east through Pakistan and India east to China, as well as in northern Australia.
This species typically grows in shallow water or on the margins of streams, rivers, wadis, ponds and reservoirs as well as in marshes, seasonally flooded depressions, wet grassland and wet woodland, in many areas it is a common weed of rice fields and on damp, disturbed ground (Cook 1996, 2004; Wood 1997, Ghazanfar 2007). It grows on a variety of substrates, including black clay soils, mud and sand.
This species is described as being used for "raising blisters in rheumatic pains, fevers etc." in Pakistan (efloras 2010) and "used as a counter-irritant for rheumatic pains" in India (Cook 1996).

This should be Ammania sp. may be A. coccinea.
I think ... is right. A. coccinea appears closest. Is it reported from the area?

If it is A coccinea then it is a new report from Haryana. However Ammania auriculata found in the area.
Me agree with A coccinea
If it is a new record, kindly wait for fruits to appear to confirm.
http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=101366
Found the post interesting;
Was trying to verify the id as a part of my learning process when I came across the keys to the species;
Please see: http://books.google.co.in/books?id=VAkHZ_ctLeoC&pg=PA588&lpg=PA588&dq...
There is also a good key in eFlora of China.
http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=101366
Since they are based on different characters, one can make a more useful key to cover species expected in the area
1a. Leaves scabrid above; hypanthium 4-angled; epicalyx prominent; calyx scabrid................A. verticillata
1b. Leaves not scabrid above; hypanthium campanulate, not 4-angled, epicalyx obscure
     calyx glabrous....................................................................................................................(2)
2a. Leaves attenuate or truncate at base; petals absent; style shorter than the ovary; cymes
     sessile and dense; flowers sessile........................................................................................A. baccifera
2b. Leaves auriculate often clasping at base; petals present; cymes pedunculate; flowers
      pedicellate..........................................................................................................................(3)
3a. Style half as long as ovary or shorter, capsule 1.5 mm in diam,; petals 1 mm long; calyx
      reflexed in fruit....................................................................................................................A. multiflora
3b. Style as long as ovary or longer, capsule 2-5 mm in diam; petals 1.5-2 mm long................(4)
4a. Capsule 2-3.5 mm in diam; flowers usually 7 (3-15); capsule as long or longer than calyx
      lobes....................................................................................................................................A. auriculata
4b. Capsule 3.5-5 mm in diam; flowers usually 3 (3-5); capsule shorter than or barely equalling
     the calyx lobes.......................................................................................................................A. coccinea

I would like to go with Ammannia auriculata Willd. for the time being.

Ammannia auriculata Willd. (accepted name) ?? : 6 posts by 2 authors. Attachments (8) 
LocationKathmandu , Nepal
Altitude:  4500 ft.
Date: 23 October 2016
Though images of leaves at the following look different:
Are the leaves variable in this species ?
Yes, leaves look little different but I could get matching for this only out of 3 listed in Nepal, specially the fruits/ seeds and the altitude.
Yes it is Ammannia autriculata Willd. and it is the accepted name also..

Pl. go through Rotala ‎(Lythraceae) page with images of species in efloraofindia.

If you find any incorrect identification, pl. let us know. If anybody can send images of other species of this genera (for incorporation in the website), if any, or can identify unidentified images, it will be really nice.
Thanks a lot to Dr. Thomas Mathew & Dr. K S Prasad for helping us on this genus.

I would like to know to which species of Rotala this plant belongs. Plant was growing in Delhi.
