[T. CALYCULATA, WilM, 



Baring- Gould informs me that he gathered two kinds of To- 

 Jieldia at Grimestunga, and considers one of them to be this species. 

 I have not seen his specimens. K., & Z. include it in their lists 

 Solander has the name, but his specimen seems to be the T, pa- 

 lustris, I have seen other specimens named T. cahjculata which 

 are 1\ palustris. I doubt if the true plant has ever been found 

 in Iceland.]

My specimen, called S, natans, gathered near Reykjavik, ap- 

 pears to belong to this species ; but Lange says that the plant 

 found near Reykjavik and at Rangarvalla is the S, angiisti- 

 folium (Mx.), the S, hyperhoreum (Lsestad,).

I think that no reasonable doubt can exist of this being the 

 plant of Smith. I have not seen the fruit, nor the floating leaves. 

 It may be the P. lucens of Lindsay • for I find that this species 

 is regarded as a form of P. lucens by Bentham, whose views 

 are generally adopted by Lindsay.
