Db. Balfoue*8 Botanical Exeurawns. 207 



July 1 1th. — On the afternoon of this day wo took a botanical walk 

 along tho banks of tho Cljdo, as far as Scotstown, and examined also 

 the banks of tho Kelvin, where it joins the Clyde. Among the plants 

 which we observed, may be mentioned, Triticum repens, Convolvulus 

 sepium, Rumex aquaticus, which was very abundant in many places, 

 Festuca olatior, pratensis and loliacea near the mouth of the Kelvin, 

 Sinapis alba, Galcopsis versicolor, Conium maculatum, Ly thrum Sali- 

 caria, Epipactis latifolia, Sedum Telepliium, Carduus acanthoides, 

 Callitriche platycarpa and vema, Geranium pratense, Senecio aqua- 

 ticus, and Mimulus luteus. The last mentioned plant, which is 

 originally from Chili, has become naturalised in many places in this 

 neighbourhood. It occurs also in other parts of the country, as near 

 Dunvegan, in Skye. 



July 13th. — Our party went by railway to Ardrossan, and thence to 

 Arran, where we spent two days examining the Flora of the island. 

 Near Brodick many interesting plants are found, which have been 

 noticed in an account of a previous trip.* In addition to the plants 

 enumerated there we may notice Cephalanthera ensifolia as having 

 been picked in the woods between Brodick and Lamlash by Mr. 

 Gourlie. On this occasion our route lay toward the northern part of 

 the island. — From Brodick we walked to Corrie, and on the way picked 

 (Enanthe Lachenalii, Erythrrea linarifolia, Juncus maritimus, and 

 Scutellaria galericulata. On the morning of the 14th July we left 

 Corrie, and proceeded along the shore to the Cock of Arran, and thence 

 to Loch Ranza to breakfast. Tho geological formations presented 

 objects of no ordinary interest. Our attention was particularly called 

 to the junction between slate and granite, the anticlinal axis, and 

 the fallen rocks, all of which are so well described by Mr. Andrew 

 Ramsay in his excellent account of Arran. The slate and carboni- 

 ferous series of rocks near the shore, we found to be, generally speak- 

 ing, unproductive of rare plants, while the new and old red sand- 

 stone and the trap furnished an excellent field for our botanical 

 researches. Among the species remarked were Juncus maritimus, 

 Scirpus pauciflorus, Blysmus rufus. Aster Tripolium, Osmunda rcgalis, 

 Cotyledon Umbilicus, Solanum Dulcamara, Scutellaria galericulata, 

 Ilabenaria chlorantha and bifolia, Sinapis monensis, Filago ger- 

 manica and minima, Ammophila arenaria, Triticum junceum, Carex 

 arenaria, Lythrum salicaria, Hypericum androsaemum, Galeopsis ver- 

 sicolor, and Lamium intermedium. After breakfast we continued 

 our route along the shore to Dugarry, where we took up our quarters 

 in some small cottages, the only accommodation which we could pro- 

 cure in this quarter of the island. In this part of our trip we gathered 

 Salicomia herbacea, and Chenopodium maritimum, Stecnhammera 

 maritima, Crambo maritima, Stachys arvensis, and Thlaspi arvense. 

 On the 15th of July we left Dugarry, and proceeded to Black Water
