storm like sea-weed. If it is annual, as I believe it to be, that 

 may explain its scarcity this year. 



Typha latifolia occurred, in Don's day, in this and Balgavies 

 Loch ; but now it is found no nearer than Milldens, in the Lunan, 

 about a mile below the point where it leaves the latter loch. 



Sparganiuvi ramosum. — In great beds, and growing to a height 

 of five or six feet. It is cut down and dried and used as litter, 

 as also are Phi-agmites comnnmis and Scirpus laaistris, when they 

 are accessible. 



Sj>. simplex and Sp. minimum, — Not abundant. 



Alisma Plantago and A. raiiicnculoidcs. — The latter on the 

 gravelly shore between the church and the curling-pond. 



Stratiotes aloides. — Don states that he brought this plant from 

 a great distance and introduced it into the Loch of Forfar about 

 1792. It has not as yet proved troublesome in Rescobie Loch; 

 but this plant and Callitriche autumnalis seem likely at no dis- 

 tant date, unless means are taken to eradicate them, to fill up 

 Loch Fithie, a smaller loch in the neighbourhood, draining into 

 one of the feeders of this loch. 



Ceratophyllum demersum. — More plentiful in the " pots " than 

 in the loch. 



Callitriche autumnalis. — Abundant. C. hamulata in one of 

 the "pots," 



Littorella lacustris. — Carpets the shores on all sides. 



Utricularia vulgaris. — In some of the pools at the head of 

 this and Balgavies Loch. 



Lysimachia thyrsiflora. — On the upper margin of the loch, but 

 not in great abundance. 



Veronica anagallis abounds in the burn that flows into the 

 loch. Lastrea Thclypteris occurs in a small marsh not far from 

 the loch. 



Caltha radicans. — In the early summer Mr W. Graham was 

 fortunate in picking up in a dry ditch, near the same place, what 

 I am in hopes will prove to be Don's plant, gathered about 1790, 

 not in the same spot, but in the same district. As, however, the 

 plant has been put upon trial, it would be premature to make a 

 positive assertion on the subject. 



Myriophyllum spicatum. — The commonest plant in the loch. 



Hippuris vulgaj'is. — In the marsh near the curling-pond, be- 

 tween the Brechin Road and the wood. 



Ny7Jiphcea alba and Nuphar luteum. — At both ends of the
