MR. 0. H. HARRIS OX THE FLORA OF GREAT YARMOUTH DISTRICT. 1 45 
marsh proper, the same lamentable deficiency was observable. 
Now, I do not say this plant has become extinct ; on the contrary, 
1 think it highly probable that it still perpetuates its kind in 
some lonely and inaccessible marsh. It must, however, have 
become very rare, and f'or this reason : I have already mentioned 
that the Port and Haven Commissioners some years ago took to 
dumping down their dredgings at the South Denes, on the east 
bank of the river. And, I have said that this, which was sport to 
them, was the death of f/i/osci/amus niper. But, although this 
process buried one rare and curious flower under a heap of refuse, 
it, nevertheless, brought quite a new flora to the bereaved South 
Denes. The mud from the bed of the river contains seeds of all 
the plants that grow on the banks and marshes on the higher 
reaches. So wo have had quite a crop of plants entirely alien 
to Denes flora. Corlileana amjlica , M'lilotus officinalis, Apium 
t/ravpiilens, Tussilajo farfara, Asha- tri folium, the commoner Rnov-x 
and Atriplex, and many other plants common to a more or less 
saline and clayey soil have taken root and flourish in the rubbish. 
So it at once occurred to me that if Atriplex pcduneulafa were 
so very common, it could not fail to be represented in this colony 
which had come down the river. But again I spent some 
interesting hours in a vain search. 
Now that I am on this subject of the rubbish heaps on the 
South Denes, it may be, perhaps, worthy of a passing comment, 
that although so many plants of the higher reaches are represented, 
Glaux maritima, one of the commonest, and from its proximity to 
the water, one of the most likely to deposit its seed in the river 
mud, has, up to the present, exhibited not a single specimen. 
The interesting family of Orcliidere are poorly represented in 
this district With the exception of the genus Orchis none are 
plentiful. Paget mentions as not uncommon, Listern ovata , 
Epi parti s palustris, Gymnadenia ronnpsea, and Malaxis pahuinsa. 
Listera ovata is to he found at Carlton Colville, but I know 
of it as growing no nearer. Ormesby Common is held, by Paget, 
to account for Epi part is palustris and Gymnadenia conopsea. 
Ormesby Common must, I think, have greatly changed its nature. 
Paget makes frequent reference to it, but in no single instance can 
I follow him, and I believe I know the common fairly well. 
Malaxis pahtdosa may still grow, as Paget says it does, in Ashby
