Hants, under the circumstances, was intended to convey 

 an intimation tliat the species remained unknown in the 

 whole county, not simply in the Isle of Wight. On simi- 

 lar grounds, when I find no authority for a species in 

 Cornwall or Kent, I usually name Devon or Sussex as 

 the next most south-western or most south-eastern coun- 

 ties ; because Pembroke and Essex, more westerly and 

 easterly, would be much less adapted for showing the 

 southern extension of the species in this country. Though 

 not a floating plant, like most of the Lacustrals, it grows

 than with the paludal plants.

Native. Littoral, Paludal. As intimated under S. la- 

 custris, the frequency of this species, if species it be, is 

 probably understated, in consequence of its being passed 

 by without particular notice, as if merely tj'pical S. glau- 

 cus. It may grow so far north as Orkney ; but my sole 

 authority for that habitat is the manuscript Flora by Dr. 

 Gillies, not revised for publication. Fries writes of this 

 plant, " at Sciqjus lacustris et glaucus, e solo salino na-
