Casual, On waste ground between the Woodstock and Kingston Roads, 
Oxford (near St. Philip’s Church), apparently on the site of a broken-up 
garden, Sep. 19, 1875, W. Whitwell. Mr. Boswell suggests it was intro- 
duced with sea-weed manure for an asparagus bed. 
Orp. LXII. POLYGONACEA, Lind. 
RUMEX, L. 
R. Hydrolapathum, Huds. Great Water Dock. 
Top. Bot. 357. Syme, E. B. viii. 51.1220. Nym. 633. 
Native. Paludal. River and stream sides, marshes. Abundant by 
the Thame, from Henley northwards, but thins out on the Cherwell above 
Heyford. It occurs also along the Thame from its entry into the county 
to its junction with the Thames about Dorchester, where it is very fine. 
On the Upper Thames it is also frequent. ‘At Radcot Bridge we direct 
attention to the luxurious growth of its flamboyant foliage, giving to ita 
gigantic character among its lighter and more graceful neighbour, Mr. 
8. C. Hall’s Book of the Thames. Mr. Wilson Saunders noticed it at 
Kirtlington with leaves forty-two inches long by eight inches broad. 
It is probably absent from the Stour district. It is a characteristic feature 
in paintings of the Thames scenery, being especially noticeable in Keeley 
Halswhelle’s pictures. P. July—Sept. 
First record, Sib. 1794. 
A plant with cordate leaves having a coarser reticulation and different 
tint to normal Hydrolapathum was noticed between Lower Heyford and 
Kirtlington, and also by the canalside near Worcester College Gardens, 
but in each case the plants were destroyed before fruiting. I strongly 
suspect these will prove to be R. maximus, Schreb. 
R. crispus, L. Common Dock.
