spots there is a pure-white variety of Epilobium 

 palustre ; while, among many other interesting- 

 plants, Alisma ranunculoides and Sagina nodosa 

 may be found at one or two places. Pinguicula 

 vulgaris is plentiful in this and all similar places. 



Beyond the next moor is the River Isla, by whose 

 banks there is a great display of Epilobiiun angusti- 

 foUum and Lonicera Periclymenum. On the wooded 

 bank the ground is covered with Luzula sylvatica, 

 almost to the exclusion of rivals ; but at some spots 

 the slender panicles of Poa nemoralis, and other 

 grasses, are waving above the stiff leaves of the 

 wood-rush. Down by the edge of the river, Bromus 

 giganteus is in fine condition ; while along the banks, 

 a little higher up, B. asper, Carex sylvatica, and 

 others such, take an important rjlace. 



Across the mouth of the Alyth Burn, on a high 

 precipice above the Isla, stand the ruins of the 

 old castle of Inverquiech, supposed to have been 

 originally a royal hunting-seat. The interior of 

 this castle is converted into a garden, and the walls 

 are almost destitute of vegetation, so that for the 

 botanist there is nothing here of unusual interest. 

 Tradition tells of a golden kettle hid somewhere 

 in the ground below, and also of a subterranean 

 passage between the cave-mouth which is seen here 

 and that on Barry Hill, a mile to the north-west at 

 a considerably higher elevation. 



Before reaching Barry Hill, plenty of Linaria 

 vulgaris, Seclum Telephium, Galium cruciatum, G. 

 verum, Hypericum perforatum, II. pxdchrum, II. 

 humijtisum, II. Jiirsutum, and the white variety of 

 Prunella vulgaris, may be observed, while Lycopsis 

 arvensis is very abundant as a weed in corn-fields. 

 Along the sides of Barry, Poly gala vulgaris is found 

 pink, blue, and white, and various species of Viola 

 form striking displays on the barer portions of the 

 ground. Pteris aquilina, Sarothamnus scoparius, and 

 Ulex europceus, are the most prominent plants here, 

 and above them frequently rise tall stems of Digitalis
