maritime or North British plants. Outside Britain also the 

 St Kilda species are widely distributed, many of them 

 occurring in Iceland, in Greenland, in Canada, in Alaska, in 

 the Rocky Mountains, north and south of the British bound- 

 ary, in Kamtchatcha, in Siberia, in Lapland, and several in 

 the Antarctic regions. 



Four species, viz.. Ranunculus Ficaria, Agrostis canina, 

 Opldoglossum vulgatum, Botrychium Lunaria, are not recorded 

 by Watson, 1883, as occurring in the " Hebrides." 



The colours of the flowers in the order of their relative 

 abundance are white, yellow, pink, and blue. The St Kilda 

 plants are all low growing, and very frequently dwarfed by 

 the strong winds. 



Among the plants of this island many are anemophilous, 

 others are capable of self-fertilisation, and a large number 

 are entomophilous. The Diptera play an important part in 

 the fertilisation of the flowers. There are several species 

 of moths on the island. They probably fertilise such plants 

 as Primula vulgaris and Silcne maritima. Butterflies, bees, 

 wasps, and possibly ants do not occur on the island. It 

 was, therefore, interesting to find in fruit several plants, e.g., 

 Vaccinium Myrtillus, Pinguicula vulgaris, which are accord- 

 ing to Midler " adapted for bees." Some species, at least, in 

 certain years, are not fertilised at all, e.g., Vicia Scpium, 

 Trifoliwni pratense, Lonicera. 



I would take this opportunity of expressing my gratitude 

 to Mr Macleod of Macleod, the proprietor of the island, and 

 to his factor Mr Mackenzie, for the kindness extended to me. 

 I would also state that I am indebted to Dr Wilson, 

 curator of the Herbarium of the lioyal Botanic Garden, 

 Edinburgh, for ready reference to books and specimens of 

 plants, and that I have had the advantage of his opinion 

 regarding certain of the species.
