VOL. XIX. (2) FLORA OF THE GLOUCESTER DOCKS 
123 
Plantago arenaria occurred in 1912, and Amaranthus 
retrofiexus in 1915. There are plenty of Chenopodiums, such as 
ruhrum, plenty of Polygonums, especially lapathifolium , also 
Fagopyrum sagittatum , but I regret that these flowers interest 
me but slightly. 
Polygonum cuspidatum, a Japanese plant, appeared here 
last 3^ear. A large patch of Euphorbia esula has been a well- 
known feature for years, and Butomus umhellatus and Acorus 
Calamus both grow regularly in the timber pool. 
In CyperacecB, the Docks themselves are not prolific, 
though, a few hundred yards away the withy beds give good 
hunting. Carex hirta is one of the few of the order which seem 
to like damp places among the timber. 
In these notes I have purposely avoided dealing with the 
flora of the withy beds and brick pools, these places being- 
very rich in sedges and the like but not being a part of the 
Docks. 
The uncommon grass Briza minor grew near Llanthony 
bridge in 1914, but disappeared last year. 
A patch of Arctium on the Docks which I noticed in 1912 
(and called in my own mind “intermedium,” simply and quite 
unscientifically because it was obviously neither majus nor 
minus) was sent last year by Mr Knight, who recognised it 
as a rarity, to the authorities at Cambridge. We sent speci- 
mens at various intervals throughout the year, and Dr. Moss 
and Mr. Evans seem confident that it is Arctium fomentosum. 
Nevertheless, they have planted some of the seed so that they 
may make certain next year. 
It will be noticed that the Docks arc peculiarly rich in 
certain orders such as the Umbcllijcrcc-, the Cruciferce, and the 
LeguminoscB and also, by my omissions, that some orders are 
very scantily represented. For instance I do not think I 
have ever seen a violet of any kind nor a rock-rose nor a milk- 
wort. I have found no Mallow except Malva sylvestris and 
there is a curious absence of Hypericums and of all but the 
commonest Geraniums such as robertianum and dissectum ; 
and even these are not frequent. Taken as a whole such large 
orders as Rosacece and the Scrophulariacece are poorly ex- 
emplified.
