Alternanthera pungens


Common names: Khaki weed; creeping chaffweed;
 
Much branched mat-forming herb, creeping, densely hairy; leaves rhomboid-ovate to obovate, up to 5 cm long, in unequal pairs, apex obtuse with mucro, petiole up to 1 cm long; flowers in sessile axillary globose heads; bracts up to 4 mm long, spiny at tip, bracteoles without spiny tip; tepals unequal, outer 2 ellptic-deltoid, 5 mm long, 3-veined, midvein produced into spine, central elliptic, inner two smaller; pseudostaminodes shorter than stamens, entire or irregularly dentate; utricle brown, ellipsoid.
 
A. pungens is a plant of dry wastelands and has much larger broader leaves, stiffer branches and very spiny tepals. The species is quite distinct but often confused with A. paronychoides. A. paronychoides is a plant of wet habitats with softer almost succulent stems, smaller narrower leaves and softer whitish tepals without sharp (pungent) tips.

AMARANTHACEAE-CHENOPODIACEAE week DSR 004: Alternanthera pungens:  Alternanthera pungens Kunth (Amaranthaceae) is a widespread species in Indian plains. It is another invasive alien species having its origin in Tropical America.  
A prostrate perennial herb, this species occupy relatively drier patches of soil as compared to other Alternanthera species.  
Within Alternanthera genus four species are noxious weeds and placed in the category of Invasive Alien Species in India; these are A.paronichioides, A.philoxeroides, A. pungens and A. tenella. Invasive alien species, though enrich the vegetation but since they also replace native species, are considered as second largest threat to biodiversity.

Yes ... Very common in Delhi along roadsides and wastelands.

Alternanthera pungens Kunth, F. W. H. A. von Humboldt et al., Nov. gen. sp. 2:165[folio]; 2:206[quarto]. 1818
Syn: Achyranthes repens L., Alternanthera achyrantha (L.) R. Br.,  Alternanthera repens (L.) Link, Illecebrum achyrantha L.
Common name: Khaki weed
Prostrate mat-forming perennial, much branched with prostrate branches; leaves broadly rhomboid-ovate to obovate, 1.5-4 cm long; inflorescence sessile globose , up to 1 cm across; tepals unequal, with sharp spiny tips.
The species is quite distinct but often confused with A. paronychoides, and the plant of latter is still labelled as A. pungens at FOI website. A. pungens is a plant of dry wastelands and has much larger broader leaves, stiffer branches and very spiny tepals. It is very common in Delhi. A. paronychoides is a plant of wet habitats with softer almost succulent stems, smaller narrower leaves and softer whitish tepals without sharp (pungent) tips.
I am uploading that separately. 
Also common in our Area Thanks Sir for detailed information about This
