4 LANARKSHIRE RAMBLES. 



on the rocks and banks herbs of rarity and consequence. When 

 in the best position for the view of the upper Fall— Bonnington 

 Linn — if he look earthward he will observe the beautiful purple- 

 tipped white blooms of the rare wood bitter-vetch ( Vicia Orobus). 

 Further down on the rocks of the left bank grows the wood vetch 

 ( V. sylvaiica), lovely with large purple-veined white flowers. The 

 shining crane's-bill {Geranium lucidum), the rock-rose {Helianthe- 

 mum vulgare), the beautiful winter-green {Pyrola minor), cow- 

 wheat {Melampyrum pratense), and twayblade {Listera ovatd) — all 

 somewhat uncommon in Clydesdale — may be culled hereabout. 

 In the woods grows the scarce broad-leaved cotton-grass {Erio- 

 phorum latifolium). Of true grasses, the graceful wood-melic 

 {Melica wiiflora) is frequent in the district; but about Bonnington 

 the rare mountain-melic {Melica nutans) and the quaking-grass 

 {Briza media) nod and quiver in the shade. In the season of 

 fruit we may moisten our lips with blaeberries {Vaccinium 

 Myrtillus) almost anywhere, and here and there vary our feast 

 with red whortleberries ( Vaccinium Vitis-Idcea), cloudberries {Rubus 

 Chamccmorus), and stone brambles {Rubus saxatilis). On moist 

 rocks near Corra linn may be seen the narrow-leaved bitter-cress 

 {Cardamine impatiens), a plant of very local occurrence in Britain, 

 and also tufts of the purple saxifrage {Saxifraga oppositifolia), 

 which is usually a dweller on the higher hills. In shaded nooks 

 grow the pale parasitic toothwort {Lathma squamaria), and the 

 whorled-leaved herb-paris {Paris quadrifolia). Of ferns one cannot 

 be very confident where there are numerous visitors on the outlook 

 for domestic vegetable pets, but the maidenhair spleenwort 

 {Asplenium Trichomanes) and the rare green spleenwort {Asplenium 

 viride) still survive in some stations though completely outrooted 

 in others. About Corehouse grounds there are some fine speci- 

 mens of trees, native and introduced, as walnut {Juglans regia), 

 Norway maple {Acer platanoides), the small-leaved maple {Acer 

 campestre), the giant redwood {Sequoia gigantea); among intro- 

 duced shrubs, the fly-honeysuckle {Lonicera Xylosteum), the cornel 

 {Cornus sanguinea), the ash barberry {Mahonia Aquifolium) ; and 

 some noteworthy stranger herbs in ponds and waste places, as 

 villarsia ( V. nymphceoides), the sweet sedge {Acorus Calamus), the 

 flowering rush {Butomus umbellatus), the columbine {Aquilegia 

 vulgaris), the Star of Bethlehem {Ornithogalum umbellatum),
