28 THE DISTRIBUTION OF HEPATICA! IN SCOTLAND 
those of the Atlantic type, have been found in England 
with Wales. The following are confined to Scotland: 
Marsupella Sprucei. Lophozia longidens. 
M. Jorgensenii. Geocalyx graveolens. 
Lophozia guttulata. Prionolobus striatulus. 
These have been added to our flora within the last few 
years and will not probably remain peculiar to Scotland. 
The following subalpine species which are common to 
Scotland and England with Wales have not been found in 
Treland : 
Marsupella ustulata. Eremonotus myriocarpus. 
M. Pearsoni. Ptilidium pulcherrimum. 
Haplozia atrovirens. Scapania Bartlingii. 
Sphenolobus Hellerianus. | Radula Lindbergii. 
One rare subalpine species, Pallavicinia hibernica, is 
common to Scotland and Ireland, but has not been found in 
England or Wales. 
The 36 species of the Britannic flora which have not 
been found in Scotland belong to the low ground, with 
the exception of one rare Atlantic species, Adelanthus 
dugortiensis, and they are almost all plants either of the 
warmer parts of Europe, or where there is at least a 
greater summer heat. 
The following are confined in our islands to England 
or Wales: 
Riccia nigrella. Haplozia czespiticea. 
R. Michelii var. ciliaris. H. lanceolata. 
R. Crozalsii. Plagiochila Stableri. 
R. ciliata. Prionolobus dentatus ? 
R. pseudo-F rostii. Cephaloziella integerrima. 
Spheerocarpus Micheli. C. Baumgartner. 
S. californicus. Calypogeia submersa. 
Fossombronia Mittenii. Anthoceros dichotomus. 
A. Stableri. 
Of the above, Calypogeia submersa, Ceph. integerrima, 
and Haplozia lanceolata may be found to occur in Scot- 
land. The remainder are less likely, being either of the 
Southern or Continental type. The Prionolobus is queried, 
as it is doubtful if it has been found in England, this
