This species, whatever it may be, whether diffusa, erecta, repan- 

 Sa or diandra, or all of them, is the only one I have yet found in In- 

 dia. It is not only common every where, but is one of the most trou- 

 blesome weeds we have. The long, fusiform, perennial roots, strike 

 so deep, as to render it no easy task to dig them up. It produces 

 blossoms and ripe seed the whole year.
