A common and rather variable weed. The bristles of the fruit are 
usually hooked at the apex ; but in some specimens they are quite 
straight. The species T. tomentosa, was founded by Bojer on specimens 
collected in Mombassa, having straight fruit-bristles and the lower leaves 
broadly oval or oblong and often 3-lobed. Many of the Indian forms 
have been referred to that, but I think they might very well be included 
in T. pilosa, and in the synonymy above quoted I have adopted this 
view.
