Here are characters I have uploaded on Facebook Groups last month Calyptocarpus vialis: prostrate perennial herb, rooting at nodes; leaves ovate, 2-4 cm long; heads usually solitary on up to 15 mm long peduncle; heads 6-7 mm long, achenes 3-4 mm long, oblanceolate, with two spreading awns in ray florets as well disc florets. Synedrella nodiflora: erect or ascending annual herb; leaves elliptic, 3-10cm long, heads usually 2-4 together, sessile or subsessile; heads more than 1 cm long; achenes dimorphic, those of disc florets like Calyptocarpus vialis but narrower, those of ray florets with triangular scales.
I don't find any distinctly pedunculate head in Dinesh ji's upload, they may be subsessile.
