PLANTS OF LISMORE 37 



excelsior, L., a few fairly large trees scattered over the island 

 (some of which may have been planted), and several smaller 

 ones among the rocks and small cliffs about the shores 

 (there appears to be little doubt that the latter are native, 

 and not merely seedlings from the possibly planted larger 

 trees), Corylus Avellana, L., common, Quercns Robur, L., 

 and Salix aurita, L., common. 



In Walker's "Essays on Natural History," 1808, and in 

 his "Economic History," mention is made of a large in- 

 digenous yew tree which grew on the sea cliff in the 

 adjoining island of Bernera. It was cut down last century, 

 and was of " sufficient size to form a large staircase in the 

 house of Lochnell." 



All the specimens seen of the following were undoubtedly 

 planted : Sambiicus nigra, L., U linns montana, Stokes, 

 Bctula pubescens, Ehrh., Alnus glutinosa, Medic., Salix 

 viminalis, L. About Kilcheran House, the most sheltered 

 part of the island, there are good-sized trees of beech and 

 sycamore. The " colonists " seen were Brassica Sinapistrum, 

 Boiss., Bursa pastoris, Weber., Viola arvensis, Murr., Spergitla 

 arvensis, L., var. sativa (Boenn.), Chrysanthemum segetnm, L., 

 Senecio vulgaris, L., Sonclins oleraceus, L., 5. asper, Hoffm., 

 6". arvensis, L., Lajiiium purpureum, L., Euphorbia Helioscopia, 

 L. About houses and in waste places were SEgopodium 

 Podagraria, L., Anthriscns sylvestris, Hoffm., Galium Aparine, 

 L., Artemisia vulgar is, L., Arctinm minus, Bernh., Cnicus 

 lanceolatus, Willd., ScropJmlaria nodosa, L. ; and by roadsides 

 mostly were GnapJialium uliginosum, L., Taraxacum officinalc, 

 Web., and Plantago major, L. 



There are three lochs on the island, each about half a 

 mile in length, their bottom being composed of a thick 

 deposit of marl ten to sixteen feet deep, according to the 

 Old Statistical Account of 1791. The vegetation in the 

 lochs is much encrusted with lime, especially among Characecs 

 and aquatic mosses. Scirpns lacustris, L., and PJiragmites 

 form tall masses at the sides in some parts, while in deeper 

 water the yellow water-lily appears to be more common 

 than the white one, this being the reverse of the usual order 

 on this coast. 



The flora of Lismore differs from that of most of the
