Around 5 years back there was a not botanists who was explaining me
this genus of grass. He threw the inflorescence on my trousers and
said "SAT GAYA NA" literally meaning, "IT GOT STUCK" so this is
Setaria :P....... though it was a funny explanation but I never
forgot it.

Pankaj ji
We used to play with this genus as well as Hordeum murinum, keeping the inflorescence between the edges of two palms and moving them, the spike used to run fast. The competition would be who does it faster.

Pankaj, your species could be Setaria verticillata which has got hooked bristles in the inflorescence that help them to stick to the cloth. I don't know any other species of Setaria have this feature.

Thats nice Dr. Gurcharan sir.
Vijay, no bristles on our plant were not hooked but much elongated...i
think they are called awns? I am too bad in grasses, but yeah it was
not this species....those bristles are too small. Once dry, may be
they all get stuck. It was at Sariska National Park.

Light yellow bristles (not green) are characteristic of S. glauca

I think most species of Setaria have barbs ob bristles to make them stick or move (our chilhood game). S. verticillata has retrorse barbs, whereas others have anterorse barbs, so it would affect whether spikes are moving forward or backward in my game.

Thanx Gurcharan ji, for the explanation. So, S. verticillata should be the one which we (during good young days!) used to play with as it had had greater grip (when compare to other species) due to retrorse barbs. Antrorse barbs are not that effective as the grip is obviously less.
