Our plant has the panicle branches ascending after flowering. 



Var. MULTicAULis (Dumort. Obs. Gram. Belg. 121, 1823, as a species). 

 Under this variety would come the majority of our Berkshire plants ; 

 it has a contracted panicle and stipitate superior glume (and I have 

 also seen it in Oxfordshire, and in Cork and Kerry in Ireland). I have 

 not seen the \ SLViety imtulipes, Syme, in Berkshire.
