INSULAR FLORAS. 295 



Georgia also occur in some of the southern islands in the 

 New Zealand region. Later on I shall have something- 

 to say, or rather repeat, in explanation of this fact. It 

 should be noted that these islands are in about the same 

 latitude as York in England ; yet the climate is now so 

 severe in South Georgia and other conditions are so un- 

 favourable to vegetation that the flora is perhaps poorer 

 than in the highest northern latitudes yet explored, and 

 entirely wanting the colour characteristic of many northern 

 flowers. For example, such charmingly beautiful plants as 

 Papaver nudicaule, Silene acaulis, Saxifraga oppositifolia 

 and Epilobium latifolium are found north of the eightieth 

 parallel ; whereas the showiest flowers in South Georgia are 

 those of a very small buttercup, so small indeed that they want 

 finding. The flora of Macquarie Island is, however, not 

 altogether devoid of colour, as witness Pleurophyllum ; and 

 Stilbocarpa is remarkable for its large rhubarb-like leaves. 



Macquarie Island is between twenty and twenty-five 

 miles long and five or six miles across in its broadest part. 

 It is generally hilly, though the hills are nowhere above 

 800 feet. The following is a list of the vascular plants 

 recorded by Mr. Hamilton (20), who visited the island 

 early in 1894. I may mention that I had most of these 

 plants under observation (22), and I do not agree in every 

 instance with his and Mr. Kirk's (23) determinations ; but 

 the divergencies are unimportant ; and there are several 

 corrections of the names given in previously published lists.
