148 S(i. GRAHnNA. 



DiGITARIA 6ANGUINALIS, Scop. 



Area (**34**j|t**jifll*13-;jf 15). 



Alien. As intimated under the other species, several 

 of its localities were formerly supposed to belong to the 

 present species, which does appear occasionally as an in- 

 troduced weed, chiefly in the jn'ovinces of Thames and 

 Ouse ; and it is said to have occurred in the neighbour- 

 hoods of Glasgow and Aberdeen ; in the former, only a 

 single plant ; in the latter, introduced with ballast. It 

 flowers late in the summer, and is very susceptible of in- 

 jury from slight frost ; so that it is not likely ever to 

 become naturalized in England. 



1266. Panicum Crus-galli, Linn. 



Area (* 3 3) [18.] 



Alien. This also is too impatient of frost, to become 

 really naturalized in England, although stations have been 

 occasionally reported, in various counties, and from a dis- 

 tant date. It would be curious to make out that Good- 

 yer's grass, foimd "by a rivulet side near Petersfield, 

 Hampshu-e," intended the Leersia oryzoides, and not the 

 present species, to which it has been constantly referred. 

 What the Panicum Crus-Galli of Barry's Orkney can be, 

 it is difl&cult to guess, for the climate of Orkney would 

 seem far too cold, and the summer too brief, for the 

 growth of this grass.
