234 THE DISTRIBUTION OF HEPATIC IN SCOTLAND 
INNER HeEpripDEs.—S. Inner Hebrides: Kildalton Woods, 
Islay (Ewing). 
Lower N. HiGHLanps.— W. Ross: Island on Loch Maree 
(Carr.): Strathcarron, u. (Maev.). 
BAZZANIA TRICRENATA (Wahl.) Trevis 
Widely distributed from Dumfries to Shetland. It is 
rare in the West Lowlands, having only been found in two 
subalpine districts. Is very rare in the East Lowlands, 
having only been found in one subalpine locality. Has not 
been found in Fife or near the coast of the East Highlands, 
but is common in most of the hilly districts of that province. 
Its apparent absence from North Perth is curious, but one 
or two other species also appear to miss this district. It 
has also not yet been found in East Inverness. It is fre- 
quent in the Forfar and Aberdeen hills, and very common 
in Mid Perth, where it ascends to 4000 ft. alt. Is very 
common in many parts of the West Highlands and Hebrides 
from sea-level, and is common in the hilly parts of the 
North Highlands. It is frequent on the Ward Hill, Hoy, 
Orkney, but is rare in Shetland, there being apparently 
few suitable localities for it. The plant of the Lowlands, 
and usually of the low ground in the Highlands, is B. tri- 
crenata (Wahl.). This is also the most common form on the 
hills, though the B. triangularis of Pears. Hep. Brit. Isles 
is frequent there, but uncommon on the low ground. In 
Shetland, the latter only has been seen. Occurs as compact 
green to reddish-brown tufts on shady rocky banks on the 
low ground, and on rock ledges and grassy slopes on the 
hills. Is very frequent in mixture with other species, as 
Avnast. orcadensis, and with mosses. The form triangularis 
(in the restricted sense) also grows directly on the rock. 
In the latter, male inflorescence is plentifully found; in 
the other, female plants are common.
