Microcala.] GENTIANE A. 195 
1904 ; in some abundance between the road and the Long 
Range near Five Mile bridge, 1914: R.W.S. Shore of Lough 
Guitane south-east of Killarney (More) Journ. of Bot. 1876, 
p. 373—-still in a few spots by Lough Guitane and very 
abundant in several places by the roadside north of that 
lake, 1887-1911: R.W.S. 
From sea-level, to 700 feet south of the Windy Gap on 
the Kenmare-Killarney road and to 800 feet near Lough 
Barfinnihy on the Killarney-Sneem road (R.W.S.). 
First found in 1845 by W. H. Harvey ; first recorded in 
Cyb. 1866, by D: Moore, T. Wright & L. Ogilby. 
This interesting and characteristic member of the south 
Kerry flora occurs in great profusion in its chosen haunts, 
bare spots in wet peaty places and on damp roadsides ; 
some hundreds of plants, from one to four inches in height, 
may often be found crowded together in a space not more 
than a yard or so in diameter. The tiny petals open only in 
bright sunshine and with an overcast sky they contract into 
a bud little larger than a pin’s head, and in this state the 
Microcala is easy to overlook. Like Centunculus, this plant 
varies greatly both in quantity and size from year to year ; 
the same spot which one season produced nothing higher 
than four or five inches, in another gave plants nearly ten 
inches high. Without being confined to the neighbourhood 
of the sea the Microcala shows a decided preference for its 
vicinity. The shores of Kenmare Bay form the head- 
quarters of this plant, while its northern range in the county, 
as at present known, is defined by a line drawn from 
the sea near Killorglin, through Killarney and thence due 
east to the county boundary. Outside its Kerry area, it is 
known only from the adjoining portion of west Cork, its 
range in Ireland being but little wider than that of Saxifraga 
Geum and much more restricted than that of Pinguicula 
grandiflora. In Great Britain the Microcala is confined to 
portions of the south and west coasts of England with an 
outlying station in Norfolk ; on the Continent it has a wide 
range from Denmark southwards.
