plant. Provinces [3] and 10, and counties of Surrey 

 (error ?), Cambridge (introduced), Lhrcohi, and Derby, may 

 be added to those mentioned in volume second. The 

 station of Duddingston Loch was an error, the sj)ecimens 

 at first supposed to have been brought thence to Profes- 

 sor Balfour by a student, having more probably been 

 brought by accident from a pond in the Botanic Garden 

 at Edinburgh. On the whole, notwithstanding the many 

 localities, and gi-eat abundance of the plant in its stations, 

 the presumption of its being an introduced alien has be- 

 come strengthened. (See Botanical Gazette, vol. iii. pp. 

 79, 136, 138). 



1109. Alisma Plantago, vol. ii. p. 475. 



This is mentioned in a list of plants seen in Orkney 

 by Miss BosweU ; and if there is no mistake in the mat- 

 ter, the area, north limit, range of latitude and of tem- 

 perature, all will require to be extended in accordance. 

 I prefer, however, to await confirmation ; as the plant is 

 a very conspicuous one, and does not appear to have 

 been noticed in Orkney by Lowe, Neill, Gillies, Duguid, 

 or Syme. The remarks under A. ranunculoides, page 

 476 of volume second, would prepare a botanist to expect 

 this species in the province of the North Isles. 



1114. Butomus iimbellatus, vol. ii. p. 478. 



Dr. Bromfield suspected that the Butomus had been 

 introduced into the Isle of Wight. It occurs in main- 

 land Hants, and in Sussex and Dorset. 



1115. Triglochin maritimuin, vol. ii. p. 479. 



Tliis was observed by me on the coast of Lincolnshire 

 in 1851, so that its provincial generality is now com- 

 pleted.
