GRAMINA. 381

832. B. sylvaticum, Beauv. False Wood Browne-Grass. 



Native ; on hedge-banks, in open places in woods, and in other 

 bushy places. Very common. July, August, or later. 

 One of the commonest grasses, abundant on the hedge-banks of lanes 

 close to Plymouth. Here its tufts of yellowish-green leaves are a con- 

 spicuous feature among the early spring vegetation. A slight variety, 

 with the spikes slender and remarkably erect, grows by the Plymouth 

 and Saltash Road, near Weston Mills Lake. I have no doubt this is the 

 plant recorded in Keys's Flo'ra as B. pinnatum, Avhich species I conse- 

 quently omit.
