Native. Paludal, Inundatal. A very obscure species, 

 and probably confused with both E. tetragonum and E. 

 palustre, if there truly is any third species to represent 

 E. virgatum, distinct from both those other two. I give 

 the provincial area according to the reported localities ; 

 making a large addition thereto in the estimated census. 

 E. Lamyi is a plant recently found in Kent, by Mr. 

 Thomas Moore, and suggested by Mr. Babington to be 

 the species imperfectly described under that name in 

 Grenier and Godron's Flore de France, and who remark 

 that it is " extremely near E. tetragonum." I have seen 

 it in several places in North Surrey and North Hants, 

 and have not hitherto satisfactorily distinguished it from 

 ordinary E. tetragonum, although there are some physio- 

 gnomical differences by which it may usually be recognized. 

 It represents E. virgatum with some good British bo- 

 tanists, although placed in a different section by Grenier 

 and Godron. (vSee vol. i. page 373.)
