he specimens from which this species is described were com- 
municated by Professor Arcangeli, according to whom this grass first 
made its appearance in rice fields in Novara in 1896, where certain 
Asiatic varieties of rice had been sown. .As a weed it is worse than 
the common P. Crus galli, and has caused Sitesi damage to the 
rice aioe Although the structure of the spikelets is practically the 
same as in P. Crus galli, the habit and particularly the leaves are so 
distinct ad those of P. Crus galli, as well as of all the other species 
of the section Echinochloa, that I have not hesitated in adopting 
Professor Arcangeli’s view that it is a distinct species——OrTro
