tima, Hippuris vulgaris, Potamogeton oblongus, Schoenus nigricans. 

 Cotyledon Umbilicus, Sedum anglicum and acre, Hypericum elodes, 

 Sinapis monensis, Glaucium luteum, Eryngium maritimum, and Carex 

 arenaria. A little to the north of Scalpsie Bay Convolvulus Soldan- 

 clla grows. 



July 1st — Proceeded by steamboat to Dumbarton, and landed at 

 the trap rocks on which the Castle stands. Here we found Malva 

 sylvestris and moschata, Conium maculatum, Smyrnium olusatrum, 

 Vicia sativa, Carex muricata, Carduus marianus, Poa maritima and 

 Sedum Telephium ; several of these plants are by no means common 

 in the neighbourhood of Glasgow. Leaving Dumbarton, wo walked 

 by the banks of the Leven to Tillichewan Castle, whither we had been 

 kindly invited by Mr. William Campbell, to whose hospitality we were 

 much indebted. Among the plants noticed we may record Ranun- 

 culus aquatilis and hederaceus, Solanum Dulcamara, Habenaria bifolia 

 and chlorantha. In the woods near the Castle, Carex remota and 

 lajvigata, Viburnum Opulus, Lastraca Oreopteris and Polypodium 

 Phegopteris occur. 



July 7th. — The Railway Train took the party to Stirling road, 

 whence they walked to Carluke and Lanark, and on the way picked 

 Rumex aquations and Jasione montana. On the morning of the 

 8th wo visited Cartland Crags, and after examining both sides of the 

 glen proceeded to the Falls of Clyde at Stonebyres, and then returned 

 to Lanark to breakfast. In this excursion many plants of interest 

 were seen, such as, Arabis hirsuta, Melica nutans and uniflora. Spiraea 

 salicifolia. Digitalis purpurea var. alba, Carduus heterophyllus. Ononis 

 arvensis, Epilobium angustifolium. Origanum vulgare, Saxifraga 

 hypnoides, Galium boreale, Helianthemum vulgare, Vicia sylvatica, 

 and in some parts of the woods, apparently naturalised, Lilium Mar- 

 tagon and Gnaphalium margaritaceum. At the Stonebyres Falls, 

 Carex pendula, Festuca elatior, Solidago virgaurea, Apargia hispida 

 and autumnalis. Campanula rotundifolia and Hypericum hirsutum. 

 After breakfast, the party visited the banks of the Clyde at New 

 Lanark, and found Carex intermedia, paniculata, remota and fulva. 

 At Cora Linn, Saxifraga oppositifolia and Asplenium viride occur — 

 the latter plant liaving been first picked in this locality by Mr. Gourlie. 

 Both these plants occur here at a much lower elevation than usual, 

 and they are not, so far as I know, met with on Tinto, or the other hills 

 in the neighbourhood. Their appearance, therefore, in this locality, 

 is by no means easily accounted for. Associated with them we found 

 Lycopodium selaginoides, Aquilegia vulgaris and Rubus saxatilis. 

 In the woods around, Equisetum Drummondii grows in profusion. 

 Near Bennington Falls, we met with Vicia Orobus, Spiraea salicifolia, 

 Campanula latifolia and Carex acuta. Mr. James Murray, who 

 visited Tinto, picked Rubus Chamaimorus and Vaccininm Vitis-Idcca, 

 on that mountain. Carum Carui was also found near Cormieston, 

 and Thlaspi arvense near Skirling.
