io Mr. Charles Bailey on 



and W. H. Beeby (26th July, 1 886, 30th August, 1 887). With 

 them is a large suite of European forms of Arenaria ciliata, 

 and Norwegian specimens of A. ?iorvegica from Saltenfjord, 

 Nordland, collected by W. Arnell (July, 1869). Mr. J. Cosmo 

 Melvill has Icelandic specimens of A. norvegica, collected 

 near Tuihiara (4th July, 1 846). 



As will be seen from the sheets of A renaria ciliata they 

 are all characterised by a difference of habit from what we 

 see in the Ribblehead Arenaria ; the latter, though having 

 a stem with several branches arising from the base, has its 

 branches erect, whereas ciliata has a much larger number of 

 diffuse prostrate leafy branches springing from the rootstock. 

 In some of the plants of ciliata now exhibited the leaves are 

 in close ranks upon the stems, whereas others are seen to 

 be in scattered pairs more like those of A. serpyllifolia,X^* 

 If the localities are examined it will be seen that the stunted 

 close-leaved forms are high alpine forms, while the broader- 

 leaved forms, with the pairs of leaves more distant, come 

 from the richer ground of the lower slopes of mountains. 

 The localities of these plants will show the wide European 

 range of the species : — Finmark : Kaafjord, Th. Fries (12th
