56 THE DISTRIBUTION OF HEPATICA IN SCOTLAND 
INNER HEBRIDES. —N. Inner Hebrides: Storr Rock, 
Skye (Ewing). 
REBOULIA Raddi 
REBOULIA HEMISPHAERICA (L.) Raddi 
Widely distributed from Kirkcudbright to Caithness, but is 
rare. It does not appear to have any special distribution 
in Scotland. It usually is found on basaltic rocks or on old 
limestone walls, though it occurs also on schist and gneiss. 
It is to be expected that this Southern species of warm and 
rather dry rocks should be more frequent in the south and 
east of the country than in the west, and this may be found 
to be the case. In the meantime, with its very local 
distribution, too few localities are known to be certain of 
this. The patches which the plant forms are sometimes of 
considerable extent, though most frequently they are only 
a few inches in diameter. Fruit, which is mature from 
June to September, is common. 
This species is sometimes classed among the mesophytes, 
but in Scotland it is distinctly a xerophyte.
