Muthu ji Your two sets of plants seem to be the same E. antiquorum , only the matter of older and younger branches: All have distinctly 3-winged stems with straight wings.
Rashida ji your first three plants are E. antiquorum without any doubt, but there is no reason to confuse the fourth photograph. It is without any wings and with spines which are spirally arranged. It should be E. neriifolia. This key from Flora of China should help in separating often confused species 4 (3)<http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=112355#KEY-1-3>Stems ± terete, leaves inserted on spirally arranged tubercles, spine shield widely separated. 29 *E. neriifolia*<http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=242321485> +Stems winged or ribbed, leaves arranged along ribs, spines shields often ± contiguous (5)<http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=112355#KEY-1-5> 5 (4)<http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=112355#KEY-1-4>Stem 3(or 4)-winged, wings thin and irregularly dentate, 1-2 cm wide. 30 *E. antiquorum*<http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=220005106> +Stem 5-7-angular, angles impressed and flat, irregularly repand-dentate. 31 *E. royleana<http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=242321511> * * * * <http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=242321511>** -- Dr. Gurcharan Singh Retired Associate Professor SGTB Khalsa College, University of Delhi, Delhi-110007 Res: 932 Anand Kunj, Vikas Puri, New Delhi-110018.
