nothing dominant, not even one of the grasses : — Holcus lanatus, 

 Scabiosa succisa, TrifoUum rej^ens, Bumex Acetosa, Senecio aquati- 

 cus, Cerastium vulgatimi, Euphrasia (in fruit), Cynosurus cristatus, 

 Plantago lanceolata, TrifoUum pratense, Leontodon pratensis, Pr2i- 

 nella, Banunculus acris, Lotus corniculaUis, Agrostis tenuis, 

 Antlioxanthum (withered), and Bhinanthus Crista-galli, the latter 

 being much more abundant in some fields than others. 



In some drier pastures to the north-east of Ollaberry (where I 

 had to divide my attention in one place between a giant bull and 

 the flora) there was nothing dominant or subdominant ; all the 

 herbage was dwarfed and indicated its moorland origin. The 

 following constituted the flora : — Festuca ovina (viviparous), Pedi- 

 cularis sylvatica, Calluna (very dwarfed), Scabiosa succisa, Juncus 

 acutiflorus, Potentilla sylvestris, Prunella, Euphrasia, Plantago 

 lanceolata, Sieglingia, Ltczula campestris, Bammculus Flammula, 

 Equisetum palustre, Carex flava, C.flacca, G. panicea, and in some 

 hollows Calthia. In less quantity occurred Bellis, Agrostis tenuis, 

 Leontodon pratensis, Nardus, Plantago mar itima, Holcus lanatus, 

 Aira flexuosa, and Juncus squarrosus. On diminutive hillocks 

 were also Thalictrum alpinum, Banunculus acris (dwarfed), Bumex 

 Acetosa, Poa annua, more Bellis, Thymus Serpyllum, and Viola 

 canina. On the rocks the chief plants w^ere Physcia tenella, 

 Platysma glaucum, and Homalothecium sericeum. Scattered all 

 over the pasture among the rest were patches of Sphagmtm acuti- 

 folium (in fair quantity), Hylocomium loreum, Hypnum squarrosum, 

 Dicranum scoparium, and Gladina sylvatica. 



On some subvertical rocks facing the sea there was an abund- 

 ance of Lecanora subfusca var. campestris, associated with Bhizo- 

 carpa petrceum, Verrucaria nucralis, Opegrapha confluens, Buellia 

 myriocarpa, and Lecanora irrubata, whilst on some neighbouring 

 rocks were Cladonia verticillata, Lecanora ferruginea, L. atra, and 

 Lecidea latypes. Physcia speciosa was growing upon old Ulota 

 phyllantha. 



The moorland above was peaty ; Calhma was usually domi- 

 nant, mixed with varying proportions of Eriophorum polystachion, 

 though I saw no place that could be termed a " Cotton-grass 

 Moor," unless a few square yards now and then could be con- 

 strued into such. There was a scattered flora amongst it, such 

 plants as Nardus, Potentilla sylvestris, Agrostis canina, Carex 

 flava, and Empetrum, the species and their relative proportion 

 altering as the land got more stony or otherwise, and where the 

 schistose rocks stood out, especially where they were much 

 exposed, they were almost covered with Leconora parella var. 

 gyrocheila (25), Cladonia cervicornis (20), Stereocaulon coralloides 

 (15), Sphcerophoron coralloides (8), Andrecea petrophila (7), Cetraria 

 aculeata (5), and about 20 per cent, of bareness. Here and there 

 were patches of Parmelia omphalodes, Bhizocarpon geographicum, 

 Lecidea contigua, and L. rivulosa. The associations in the rock- 

 crevices consisted of tufts of Polytrichum piliferum, Empetrtnn, 

 Nardus, Carex flava, and sometimes Potentilla sylvestris. 



The moorland towards the Whaling Station at Eonas Voe had
