MR. II. D. GELDART ON 
Cambridgeshire by an arm of the sea ; practically, the county is 
insular still. Mr. Galpin places the springs from wliich the two 
rivers, the Waveney and the Ouse, rise at 000 yards apart, but 
I believe the two s}^stems of drainage running East and AVest are 
divided only by a road a few yards wide. Mr. Galpin, following 
the hStudent’s Flora,’ describes Corynephorus canescenx, the curious 
little seaside grass which has been found at Homersfield, seventeen 
miles as the crow flies from the sea, as an annual. This is not accord- 
ing to my own experience. The hard tufts of leaves from which the 
flowering stems rise on the Denes at Yarmouth are certainly many 
of them more than one year old. In this I am confirmed by Parnell, 
‘Grasses of Great Britain,’ who says annual or biennial; and by 
Syme in ‘ English Botany,’ third edition, who calls it perennial. 
There are many surprises in Mr. Galpin’s list, both in the 
presence of plants unexpected in such a district, and the total 
absence or rarity of others which one would certainly have supj^osed 
to be present, or not uncommon. Among the former are : 
Anemone apennina 
Dianthus armeria 
SiLENE NUTANS 
OXALIS CORNICULATA 
Hippocrepis COMOSA 
ChRYSOSPLENIUM ALTERNIFOLIUJr 
Buplburum rotun difolium 
Galium tricorne 
Campanula latifolia 
Veronica verna (extinct) 
Marrubium vulgare 
Apera interrupta 
Corynephorus CANESCENS 
Bracitypodium pinnatom 
Aspleniuji viride 
Ceterach officinarum 
Cystopteris fragilis 
Equisetum iiyemale 
Conspicuous by their complete absence within the six-mile limit 
are : 
Corydalis claviculata 
Viola tricolor 
POLYGALA SERPYLLACEA 
Medicago falcata 
POTERIUM SANGUISORBA 
,, OFFICINALE 
Pyrus AUCUPARIA 
Drosera (whole genus) 
Centaurea cyanus 
Erica (both species) 
Pbdicularis palustris 
EpIPACTIS PALUSTRIS 
Convallaria majalis 
( except as intro.) 
LuZULA MAXIMA 
SciRPUS CA3SPITOSUS 
Etiynchospora alba 
SciIOiNUS nigricans
