Its a trap (boh ceumeucet or andropogon aciculatus)

Have you ever been to jungle to be disturbed by weeds? Yaps as i felt yesterday, i feel itch when i see this is happening, my skirt is full of this grass.

This is a needle grass in its scientific appellation andropogos aciculatus, in aceh language named "boh Ceumeucet" or "boh lonte" means flirtatious grass, perhaps called flirtatious because it is directly attached when we approach it.
So be careful when approaching the needle grass. If not you will be teased.lol
