Given below are the relevant key characters from Flora of India:
a. Stems not winged ---> Sphaeranthus amaranthoides
b. Stems winged:
b-i) wings entire; flower-heads <1 cm across ---> S. africanus
b-ii) wings toothed; heads up to 2.5 cm across; leaves single-dentate ---> S. senegalensis
In S. indicus, the leaves are double-dentate.
 
Keys
 1a. Stems not winged or rarely narrowly winged; glomeruli conical, subsessile, brownish;
outer florets not more than 4 ---------------------------2. Sphaeranthus amaranthoides
 b. Stems winged; glomeruli spherical or ovoid, pedunculate, glabrous, white, purple or violet; outer florets more than 4 ------------2
2a. Wings entire, glomeruli not more than 1 cm across; peduncles glabrous; involucral bracts not ciliate at apex----1. Sphaeranthus africanus
 b. Wings toothed; glomeruli up to 2.5 cm across, peduncles pubescent; involucral bracts ciliate at apex------------------3
3a. Leaves double-dentate and with stalked glands ----------Sphaeranthus indicus
 b. Leaves single dentate and with sessile glands -------------Sphaeranthus senegalensis
