 of tropical and temperate regions. It has been recorded 

 once or twice in England as a casual. 



Gastridiiim australe, Beauv. Native in dry pastures 

 in the east of Europe. Now widely spread as a weed 

 of cultivated ground in most temperate parts of the 

 world. In England it occurs under the latter conditions, 

 sometimes even in abundance. 



Heleochloa schoenoides, Host. It was found in 

 England on waste ground associated with certain weeds 

 which pointed to its introduction with foreign corn. 

 Native of the Mediterranean region and the East. 



Hordeum jubatuiu, L. Several times recorded from 

 waste ground in England. It was probably in all cases 

 a grain-sifting casual. Native of the New World. 



[Hordeum murinum, L. Probably native on the coasts 

 of North-West Europe. In England, except near the 

 sea, it always grows (or at any rate is always so recorded) 

 in waste ground around villages and towns. It is

Hordeum vulgare, L. Barley is not uncommon as 

 a stra<i5ler from cultivation.
