Remarks on Some Aquatic Forms and Aquatic 

 Species of the British Flora. By Arthur 

 Bennett, A.L.S. 



Dr. Gliick of Heidelberg is engaged on a study of the 

 aquatic species of the European flora ; and Dr. Rothert of 

 Krakau, Austro-Hungary, on a monograph of the genus 

 Spa/rganiv/m,. 



Both have been this year in England to study our collec- 

 tions, and I had the pleasure of seeing them at my house 

 and talking these matters over with them ; these notes are 

 a result, and we trust that our species will be examined. 



To Mr. G. West's examination of about 140 Scottish 

 lochs we are indebted for many hints as to the aquatic 

 condition of various species, both of terrestrial, semiaquatic, 

 and aquatic species. 1 In these two papers Mr. West gives 

 the vegetation of these lakes (including in many instances 

 mosses, lichens, and algas) in their submerged, littoral, and 

 surrounding conditions. 



He discusses many subjects, and these papers, it is to be 

 hoped, will be followed up by others, after the manner of 

 Dr. Magnin with the French and Swiss lakes of the Jura,* 2 

 and the United States in Bull. Michigan Fish Commission, 

 No. 2. " The Plants of Lake St. Clair," A. J. Pieters, 1894. 



1. Ranunculus Flammula, L., var. natans (Pers.). — This 

 is a remarkable form of Flammula found by Mr. West in 

 two places, a floating form at the margin of peaty pools 

 about Morton Lochs, Tents Muir. "A strong plant 2 to 

 3 feet long," and a submerged form in the margins of lochs
