Naias marina, Linn. Sp. Plant, ed. i t. 2. (1753), 105. 
In the place cited Linnaeus gives no actual description, relying 
on the figures and synonymy he quotes, which, however, 
cannot be mistaken. 
It is now 26 years ago that Naias was found in Norfolk, 
and no other county has yet been recorded for it. Still, 
looking at its distribution, &c., on the Continent, there is 
really no reason why it should not occur. In Sweden it

dish. It varies from 30 cm. to 70 cm. high. 
The finding of this interesting Norfolk plant came about 
in the following way : In the winter of 1882-3, I had been 
comparing a Dutch Flora with our Eastern Counties, with

to be found in. So on July 20th, 1883, my daughter and I, 
with Mr. A. G. More of Dublin, went to Liverpool Street 
Station, had tea together, and Mr. More saw us off by the
