First record, Arundo vallatoria foliis ex luteo variegatis. Found by the 
river Thames not far from Oxford, Ray, Stirp. 1690. 
Phragmites is on record for all the districts except the Stour, in which 
doubtless it occurs. It is extremely abundant by the Thames side and 
the Cherwell. Thame and Ouse have it also frequently on their margins. 
It occurs in great profusion in the marsh under Headington Wick Copse, 
where it forms from November to January a beautiful show. The wind 
has driven the feathery seeds from here across the fields towards Elsfield, 
the hedges retaining a considerable number, so that now a thicket of them 
runs along an elevated hedgerow on a dry sandy soil, very ditferent from 
its usual habitat. By the river above Bablock Hithe it attains a height of 
ten feet. Near Headington Wick, Phragmites nigricans, G. and G. (a 
starved form ?) has been noticed.
