300 THE DISTRIBUTION OF HEPATIC IN SCOTLAND 
MaporHeca THusa (Dicks.) Dwm. 
This rare species has only been found in a few localities 
on the coast, or near it, from Wigtown to the Outer 
Hebrides on the west side, and from Haddington to Kin- 
cardine on the east. It occurs on different formations, but 
the localities are too few to enable any preference to be 
noted. It is nearly always confined to exposed rocks on 
the sea-shore, where it forms large yellowish-brown or dark- 
green patches. The Loch Ness locality of Menzies, on which 
Dickson is supposed to have founded the species, is many 
miles inland, and unlike any recent locality known for the 
plant. I do not know if Menzies’ plant has been recently 
examined, but from the locality I should expect it to be one 
of the more entire-leaved forms of MW. levigata. As with 
our other members of the genus, female inflorescence is 
common: the male plant has not been seen. 
This is a Western and Mediterranean species in Europe, 
and is the only one of this group which has been found in 
more localities on our east than on our west coast. The 
great majority of our purely Atlantic species are absent 
from the east coast; the few which are present are very 
rare. If we consider this species as a Southern one which 
extends up the west coast of Europe, its preference for our 
drier and more sunny east coast agrees with the distri- 
bution of such a Southern species as Lunaria cruciata. 
The Madotheca also does not occur in moist, sheltered 
localities as do nearly all Atlantic species, but prefers 
exposed places in districts of small rainfall.
