Dr. Balfour's Botanical Excursion. 211 



Erythra3a linarifolia are also found on this shore. The latter plant 

 is found in many situations on the west coast, such as the shores of the 

 island of Arran. 



On leaving the shore, the party proceeded inland towards Galdenoch, 

 and thenco to Lochnaw. At the latter place, through the kindness of 

 Sir Andrew Agnow, and with the assistance of Dr. Greville, and the 

 Rev. T. B. Bell, we were enabled to examine the loch in the neigh- 

 bourhood of the castle. We were rewarded with specimens of Lyco- 

 pus europseus, Sedum rupestre, Potamogeton praslongus, Sparganium 

 natans, Callitriche autumnalis, Epilobium angustifolium, Eleocharis 

 multicaulis, and Prunus insititia in fine fruit. 



On the 11th, after picking Ophioglossum vulgatum, Botrychium 

 Lunaria, and Senebiera Corouopus, in stations near Portpatrick, 

 pointed out by the Rev. Mr. Urquhart, we proceeded by the shore 

 towards the Mull of Galloway, where we meant to take up our quarters 

 for a day or two. We visited the ruins of Dunskey Castle, placed on 

 remarkable rocks projecting into the sea, and thence walked to Port 

 Spittal, and Port Float. The greywacke cliffs along the shore present 

 characters similar to those exhibited by the rocks to the north of 

 Portpatrick. 



Between Dunskey Castle and Portpatrick, Orobanche rubra was ob- 

 served. This plant is usually associated with basaltic rocks, at least, 

 if I may judge from the localities near Edinburgh, in the Hebrides, 

 and in Ireland. In the present station, it appeared to grow on Grey- 

 wacke, but I fear the observations made were not sufficiently accurate. 

 Along with it we noticed Agrimonia Eupatorium. We also picked 

 Isolepis Savii, an abundant plant in Wigtonshire, Euphorbia portlan- 

 dica, Lamium intermedium not previously known I believe to exist here, 

 Pyrethrum maritimum, which may possibly be a peculiar maritime 

 variety of P. inodorum, Radiola millegrana, Daucus Carota in a re- 

 markably dwarf and fleshy state, resembling D. maritimus, Euphrasia 

 officinalis assuming also a thickened and diminished appearance, from 

 its vicinity to the sea, Anagallis tenella in all wet spots, and Anagallis 

 arvensis in the fields. 



From Port Float we walked to Chapel Rosan Bay, and thence, by 

 Logan House, to Port Logan, or as it is sometimes called, Portnes- 

 sock. After paying a visit to the famous fish pond, we proceeded 

 to Kirkmaiden and Drumore. We gathered during this part of our walk 

 several common species of Salix, Euonymus europjcus, Hieracium 

 inuloides, Conium maculatum, Lepidium Smithii on every road-side, 

 Helosciadium nodiflorum, or, as some may call it, H. repens, for it ap- 

 pears to me that the distinctions between these species are by no 



districts of Aberdeenshire, that the former contained iodine, and that soda was more 

 abundant in them, while potash prevailed in the latter. Annals and Mag. Nat. Hist.
