Colonist. Agrestal. Foimd only in cultivated fields 

 and occasionallj^ by road-sides ; being very uncertain and 

 usually temporarj' in its stations. More frequent in the 

 southern provinces of England ; and probably kei)t up in 

 those of Scotland, or at least in the Highland provinces, 

 only by renewed introduction. For a species thus doubt- 

 ful in its nativity and jjermanence, the area, the northern 

 limit, the range of latitude, &c. must be conjecturally or 

 arbitrarily decided upon. Tsvo quite different plants have 

 passed under the name of B. velutinus ; one of them 

 being a pubescent variety of B. secalinus ; the other 

 being a state of B. moUis, with close panicles and longer 

 pubescence than usual, mostlj^ of short stature, and 

 chiefly found near the coast. This latter is the B. velu- 

 tinus of Hooker and of the majority of botanical collectors 

 in England. I have myself found the pubescent state of 

 B. secalinus in Sussex only ; and have never received a 

 specimen of it collected by any other Enghsh botanist.
