of the Rhymney; for there were neither railway embankments, coal 

 tips, nor large quarries in Glamorgan in 1724. At the present time, 

 however, it is chiefly found on " made " ground. It is quite incapable 

 of growing in " moist meadows " amongst grass. Once the fertility 

 of the habitat rises to the point necessary to support a luxuriant 

 crop of grass, the fate of the cudweeds, "hardy perennials" though 

 they may be, is sealed. The plant is strictly adapted to the " open 

 formation" — hence its occurrence on sand-dunes, river gravels, 

 railway embankments, mountain screes, coal tips, slag hills, and even 

 " bare rock " is readily understood.
