60 NOTES ON THE FLORA OF DUMFRIES. 
in luxuriance and to a great size near Comlongan Castle and the 
Brow Well. Polemoniwn ceruleum 1 noticed at one or two 
pomts on the New Abbey road. 
On that part of the banks of the Nith immediately below the 
town, called the Dock, Galium boreale and Achillea Ptarmica are 
abundant, springing in large tufts from the side of the dock 
immediately below the Old Bridge; also a Campanula, which 
resembled at a distance C. latifolia or C. Trachelium, or a form 
intermediate between them. 
Of littoral plants, growimg on the banks of the Nith below the 
New Quay, past which the tide of the Solway flows daily, Aster 
Tripolium, Plantago maritima, and Honckenya peploides are abun- 
dant in the salt marshes. Onxonis arvensis and its spinous va- 
riety is common on the sides of the embankment which defends 
the east bank of the river. Nearer the sea Hrythrea pulchella 
occurs: some look upon it as a mere dwarf variety of the com- 
mon £. Centaurium : it is common in the downs below Caerla- 
verock Castle, as is also Trifolium ornithopodioides.. On the 
Southwick cliffs, on the shore of the Solway, Osmunda regalis, 
Crithmum maritimum, and Asplenium marinum are found. 
Of aquatics, Nymphea alba covers acres in Loch Kindar, at 
the foot of the huge syenitic mass of Criffel, the highest hill in 
the district ; when in flower the scene is one of great beauty ; it 
also occurs in several other lochs, which are very abundant in 
the district. In the same loch Lobelia Dortmanna is found. The 
Typhas are found at Lochmaben. The water of the fosse sur- 
rounding the ruins of the fine old castle of Caerlaverock is co- 
vered with the showy little Ranunculus aquatilis. The majority 
of the plants are devoid of the entire floating leaves, which con- 
stitutes a not uncommon variety. Both species of Bidens are 
found at Lochmaben. 
On the banks of the Glen water the Hart’s-tongue Fern grows 
to one or two feet in length, and many of the fronds, which are 
extremely handsome, are bi- or trifurcate at the apex. Further 
up the stream, “on a grassy bank of fifty square yards, grow 
Meum athamanticum and Betonica officinalis.’ Dr. Gilchrist has 
not found them elsewhere in Dumfriesshire. 
Of marsh plants, the three Droseras grow together in Dalscone 
Moss, two miles to the east of the town. D. rotundifolia is plen- 
tiful in the Lochar Moss, where Menziesta polifolia and Ranun-
