Extends further north than any other species of Arenaria: 
found in Goose Land, in the island of Novaya Zemlya, during 
the ‘ Nordenskiöld ' Expedition at lat. 72? N., also in Greenland, 
lat. 723-74" N. Found throughout the Arctic regions north of 
Europe and Siberia, —Iceland, N. Norway, Lapland, the island of 
Vaigatch, Aretic Russia, the territory of the Samoyedes, even 
to the rugged west coast of Spitzbergen. Authentic specimens 
of A. ciliata had not been examined from Spitzbergen, the present 
most northerly limit of any species of the genus, at the time of 
writing my former paper on Arenaria*, where the northern 
limit is given as that of the island of Novaya Zemlya. Sir J. D. 
Hooker + says that the range of the species extends as far south 
as the island of Crete. This is due probably to the error in 
Sibthorp’s ‘Fl. Grzca, t. 438, where the plant figured as 
Arenaria ciliata is A. gracilis var. cretica. It extends no further 
south than Spain. In the mountains of Sligo, in the west of 
Ireland, the plant ascends to 500 metres ; and there is a specimen 
from here preserved in Buddle’s Herbarium under the name of 
“Lychnis alsinoides parva, flore albo minimo.” On the Stelvio 
Pass, in the Rhetian Alps, where the three frontiers of Switzer- 
land, Austria, and Italy meet, specimens have been found, 
“cording to Parlatore, at 2800 metres. Near the bridle-path 
on the Col de Fenêtre of the Great St. Bernard, in the Swiss 
‘anton of Valais, specimens were found by M. Gaston Tissandier 
& 2750 metres. These are the highest altitudes in the Alps 
*corded for the species. It was from specimens gathered in the 
Stelvio Pass that Parlatore drew up his description of the species
