SKETCH OF THE FLORA OF THE PROVINCES ele 
Flotowianus, Scapania rosacea ?, and the var. germana of 
Radula Lindbergii. These species, with the exception of 
the first-named, which has been found in Moffatdale, are 
apparently confined in the West Lowlands to the Kirk- 
cudbright hills. The hepatic flora of these hills has a 
considerable resemblance to that, of the English Lake 
District, and this is not seen in any other part of the 
Lowlands. 
The Atlantic species of the West Lowlands are found in 
much smaller quantity than in the West Highlands. They 
are almost all very rare in this province, and are mostly 
confined to the neighbourhood of the shore or to sheltered 
ravines in the south-west. The following have been found : 
Metzgeria hamata, Sphenolobus Pearsoni, Plagiochila 
spinulosa, P. punctata, Lophocolea spicata, Saccogyna 
viticulosa, Lepidozia Pearsoni, Pleurozia purpwrea, 
Madotheca Thuja, Scapania gracilis, Radula aquilegia, 
Cololejewnea microscopica, Harpalejeunea ovata, Frullania 
microphylla, F. germana. There are also the usually 
Western species Microlejewnea uliciona and Lejewnea 
patens, and the Western and Mediterranean Marchesinia 
Mackari. 
The species which occur in peat-mosses are much the 
same over the whole of Scotland. In the low-lying peat- 
mosses of the Lowlands, a very few of the subalpine species, 
as Leptocyphus Taylori, are absent or very rare, while they 
are common in the low-lying mosses of the Highlands. 
Also in the West Highlands and Hebrides a conspicuous 
feature of many peat-mosses is the abundance of Plewrozia 
purpurea, this species being rare in the West Lowlands, 
absent from the East Lowlands, and mostly so from the 
East Highlands. With such exceptions, the constituents of 
the flora do not much differ, though their relative fre- 
quency may vary. 
East LOWLANDS 
A large part of this district is under cultivation. The 
hilly districts comprise the Pentland, Moorfoot, and Lammer- 
moor Hills, running through the centre of the district, and 
a higher range forming the southern boundary, the highest
