as perhaps the most widespread of any of the more decora- 

 tive plants. Cruciferce appeared more plentiful than was 

 the case in Lapland — Caryophyllaceae not being quite so 

 prominent. 



It is useless, however, to dwell upon the predominance 

 of any one colour, so dependent did such appear to be 

 upon the nature of the locality, whether it favoured the 

 spread of one class of plants or another. A mere com- 

 parison as to the relative numbers of plants with flowers of 

 one colour or another would be quite or almost useless ; 

 such would show to us that a large proportion of the 

 collected species were those with highly coloured flowers, 

 which individually appeared to be quite as brightly coloured 

 as with us ; but, as before mentioned, usually they are but 

 sparsely distributed. 



It is very difficult to indicate with any precision as to 

 the relative frequency or scarcity of the plants common 

 to these regions. I have endeavoured to indicate the 

 commonest in the notes attached to the Summary, 



It is hoped that the present paper may be followed by 

 one dealing especially with the distribution and the remark- 

 able variation of some of the species herein mentioned. 



My collections have been presented to the Herbarium of 

 the Eoyal .Botanical Garden, Edinburgh.
