duplicates at present available. Florida is already comes wen 
a species not known elsewhere—P. Curtisii Morong, found o 
r. A. H. Curtis. Very few specimens of this are extant, a it 
is little known. It is placed by Morong ( ne Amer. Naiad, p. 86), 
species is nearest P. trichoides Cham. ij hk especially to some 
original specimens I possess of P. tuberculatus Guépin from Angers, 
France. Dr. Small seems to have overlooked the — of

GLYCERIA FESTUCAFORMIS IN IRELAND. 
Dr. Renpie’s paper in this Journal for 1908, pp. 858-6, 
this grass, which was discovered by Mr. Praeger last summer 4 
Co. Down, is most interesting. In the article in the Irish Natural- 
ist, from which Dr. Rendle quotes, the lucky finder of this plant 
expresses himself as perfectly goo that it is indigenous to 
as he thinks, it was impossible for the seeds to 
have been introduced by land or sa from the shores of the Medi- 
terranean Sea, which is the og place to Ireland where Glyceria

Filipenoxi on the shore of Strangford pe tice I think it probable

No doubt, as Mr. Praeger writes, “in the whole of Strangford 
Lough there is no port where for eign vessels call. The sea traftic 
is confined to small local boats with cargoes of coal, bricks, and so

duction by land is equally out of the questi For there is a

surprising discovery, and previous to the publication of his account 
of it in the Trish Naturalist = Oct. 1908, and I wonder how it 
escaped his experience and acuteness. 
About eight miles pram ye tr porennt the Lough, north-west from 
the Ards locality, i is the little town of Comber, situated barely half 
a mile from the shore of Strangford Lough. In it is a well-known, 
old-established, and flourishing distillery, where barley from various 
sources is from month to month used in the manufacture of whisky. 
When this occurred to me, and I ‘tabellooted that many alien plants 
are found growing on an = ground near distilleries, the seeds 
aving been imported with foreign grain, I enquired from the 
manager of the Comber pmol) whether grain from a Mediterra- 
nean port was ever used by his firm; and his reply was:—** We 
have imported barley from Ricwis, but have not had any of this
