200 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
British species growing plentifully in the excavated soil near the 
Vale Castle, and we afterwards found it plentifully not only in such 
situations, but also by the sides of roads, and other dry bare places 
in the northern part of Guernsey, and also extending westwards to 
Vazon and the Grande Mare. On my visit to Alderney I found it in 
Braye Bay and about quarry debris farther east. I have also de- 
tected a piece among some plants I gathered at St. Luke’s, Jersey, 
in the previous June, but this was on some recently disturbed waste 
ground. In Corbiere’s ‘ Nouvelle Flore de Normandie ’ it is reported 
as a southern species naturalised for upwards of 40 years at Cher- 
bourg. From the fact of its not being a native of western France it 
may be held to be also adventitious in the Channel Islands, and in 
an area so disturbed by the operations of man as these small islands 
it must be difficult to decide upon the indigenity of the species. On 
the one hand there are the facts of its absence from the opposite 
coast of France as a native species, and that it has hitherto escaped 
observation in these islands, while the geographical range is not 
strongly in favour of its being native here, yet on the other hand it 
may be urged that it extends up tlie western coast as far as Spain 
and Portugal, that it is extremely like Agrostis alha^ var. stolonifera, 
in appearance, and chooses similar situations, while in its undoubtedly 
native area it prefers ground which has been disturbed by man, and 
that it is now very abundant in Guernsey. — G. Claridge Druce.

Among the recent publications interesting to our members may 
be mentioned ‘ Alien Flora of Britain,’ by Stephen Troyte Dunn, 
B.A., F.L.S., pp. xiv., 208, price 5^., West, Newman and Co., which 
gives a brief account of many of our alien species, a subject which 
is receiving greater attention by field botanists at the present 
time.
