142 THE DISTRIBUTION OF HEPATICZ IN SCOTLAND 
LOPHOZIA HETEROCOLPA (Thed.) Howe 
Jung. heterocolpa Thed. 
This rare species has only been found in Mid Perth, and 
mostly on the hills where there is some limestone present. 
S.E. Hicguianps.—Mid Perth: Craig-an-Lochain, Killin, 
alt. 1700 ft., with Bryum pseudo -triquetrum, Mnium 
orthorrhynchum, M. punctatum, Swartzia montana, Hylo- 
comium splendens, 1901 (Macv.); Cam Creag, Killin, with 
Marchantia polymorpha, 1909 (D. A. Jones); Ardeonaig, 
Killin, 1909 (S. J. Owen). 
LopHozia optusa (Lindb.) Evans 
Jung. obtusa Lindb. 
This is a very rare species in Scotland, though it will 
doubtless be bound to have a wider distribution when 
better known. At present it has only been found in the 
Breadalbane mountains and in the West Highlands. Its 
usual locality is among alpine species, and it probably has 
been found to about 3000 ft. alt., but in one place on the 
west coast it occurs close to sea-level. The Scottish 
specimens are sterile. 
S.E. HiGHLANDs.—Mid Perth: Ben Lawers, among Mar- 
chantia polymorpha, 1909 (D. A. Jones and H. H. Knight). 
W. HicHLanps.—Dumbarton: Bank in Arrochar Wood, 
nr. sea-level, 2, with Dicranwm majus and Plagiothecium 
undulatwm (Macv.). W. Inverness: Ben Gaire, Moidart, 
alt. ca. 1700 ft. on rock ledge, with Anastrepta orcadensis, 
1898 (Macv.): Ben Nevis, alt. ca. 2000 ft., among Hypnum 
Schreberi, 1909 (H. H. Knight). 
LOPHOZIA VENTRICOSA (Dicks.) Dum. 
Jung. ventricosa Dicks. 
One of the most generally distributed and common 
species both on the low ground and on the hills. It is 
rather uncommon in the region of cultivation in both West 
and East Lowlands, but is common in the subalpine region, 
and occasionally very common, as in the Upper Clyde and 
in part of the Upper Tweed districts. It continues un-
