41 G William Evans on Zostera nana. [sess. liii. 



mens on the table were gathered at the last-mentioned 

 locality a few days ago. 



The Herbarium at the Eoyal Botanic Garden contains speci- 

 mens from ]\Iontrose basin, with which I have compared mine. 



Wigdeon feed on this Zostera as well as on Z. marina, 

 their favourite food, and it was while studying the habits of 

 these ducks that my attention was first drawn to the plant. 



On the Occurrence of Calamagrostis stricta, var. borealis, 

 Hartm., in Scotland. By Arthuk Bennett. 



(Read 14th March 1S89.) 



Last summer Mr G. C. Druce, r.L.S. of Oxford, sent me 

 specimens of a Calamagrostis he gathered on the banks of the 

 Tay, in Mid Perth, in a marsh, which I saw at once was not 

 our usual state of stricta ; and Mr Druce recorded the plant 

 in the Scottish Naturalist, with a note, that I thought it near 

 horcalis. He has lately sent specimens to Professor Haeckel 

 of St Poeltens, and he decides that it is the borealis of 

 Hartmann's Flora. This is again a most interesting addition 

 to the Scottish flora, and another link in. the evidence of its 

 close similarity to that of Scandinavia. 



I give its synonymy and distribution, with the original 

 description and remarks of L;estadius, its describer. 



Calamagrostis borealis, L. L. La3stadius, in "Anamarkningar

 Arista subdorsali, lana corolla brevior,caulis foliatus. Pani- 

 cula stricta patens, folia radicalia dilata, aspera, stricta, elongata. 

 Hujus forma primaria paludosis in Pajala et Kengis.
