1857.] SCOTTISH BOTANY. 227 



large purple flowers^ which close before noon^ or during dull, 

 rainy weather. It grows in marshy places^ beside the Comarum 

 palustre, with which the moor is covered. Like the Rumex al- 

 pinus, this plant is also cultivated for culinary purposes in the 

 cottage gardens by the wayside ; all the inhabitants assert that 

 they obtained all their roots originally from the moor, so that it 

 is not an escape from cultivation. We found the Reseda Luteola 

 very abundantly here and there among the fields near the Rum- 

 bling Bridge, over which we passed and obtained a hurried glimpse 

 of the terrific spectacle below. 



When we arrived at Dollar, we left our vehicles at the inn, 

 and went up the hill immediately to the woods around Castle 

 Campbell, where we proposed to spend the day. We found the 

 cool shadows of the trees very refreshing after having toiled up 

 the steep ascent under the unmitigated blaze of a vertical sun, 

 and spent several hours very pleasantly in wandering amid their 

 green secrecies and in visiting the magnificent ruins of the old 

 castle, situated on the summit of a green eminence, entirely sur- 

 rounded by deep ravines, through which flowed two streams called 

 Law and Sorrow, and commanding an extended and magnificent 

 view of the romantic scenery in the neighbourhood. After 

 dinner, which we discussed with considerable hilarity, under a 

 dense canopy of green leaves, which cast their flickering lights 

 and shadows over our snowy cloth and its adornments, seated on 

 old, mossy stumps of trees, which we had torn up by the roots 

 from the surrounding braes, and charmed with the soft, dreamy 

 music of the stream beneath us, we proceeded to botanize among 

 the woods, and were in a short time rewarded with the disco- 

 very of Equisetum Drummondii, first found there by Dr. Dewar j k}J^-"- 

 of Dunfermline, Circcea alpina, Hookeria lucens, Anomodon 

 curtipendulum, Sticta Pulmonaria, and various other Cryptogamic 

 plants. Ferns seemed to be unusually abundant, owing to the 

 dense shade and humidity of the ravines. Limited as was the 

 area we examined, we found in it upwards of eighteen species, 

 some of which were very rare and interesting. Following the 

 course of one of the streams out of the wood to the entrance of 

 Glencairn, an upland valley surrounded by huge, round, grassy 

 hills, towering up to a height of about 200 feet, and producing a 

 somewhat alpine vegetation, I was delighted to find the lovely 

 little Hymenophyllum Wilsoni, growing in immense patches of
