Don's Plant of Ranunculus nivalis. While recently staying 
with Miss Palmer I examined a few specimens collected by George Don for 
her grandmother, the fourth Countess of Aylesford, which I had not pre- 
viously seen. One of these was labelled, " lianunculus nivalis, Sp. PI. 1321. 
High mountain near Mar Lodge, Aberdeen." This is not the Liiiivcan 
nivalis; but is closely allied to R. acris, L. var. 'pumilus, Wahl., which I 
have collected from Corrie Scheadna, Easterness, and Glen A'an, Banff. 
It may interest Scotch botanists to learn that the very interesting and 
beautiful drawings of British plants made by the Countess of Aylesford are 
now in the possession of her grand-daughter, the Countess of Dartmouth. 
They probably include several of Don's plants.
