1 66 ANNALS OF SCOTTISH NATURAL HISTORY 



any collecting and observing ; but the following pages will 

 show that while he could he has done good work. 



I shall be extremely glad if any one can add to these 

 records, and will publish the additions, no matter how 

 trivial they may seem. It is only by many units that we 

 can build up a floral record of any county. 



Working through Messrs. Balfour and Babington's 1841 

 List, 1 there is little to comment on, as a first-list notice was 

 of course taken of species rather than of critical forms. 

 The Cerastium atrovirens, Bab., is simply a state of C. 

 tetrandrum, Curt. Potentilla Tormentilla is given as " flourish- 

 ing at a height of 3000 feet." There is no hill in the Outer 

 Hebrides that attains that altitude, Clisham in North Harris 

 being the nearest to it (2622 feet) ; but at that date the 

 altitudes were little known. Taraxacum officinale " Upon 

 the upper part of Langa (2102 feet) we found a variety of 

 this plant, approaching palustrc, but with descending lobes 

 to the leaves, and the outer scales of the involucrum lanceolate- 

 attenuate." Under Eriophorum they give both angusti- 

 folium and polystachion ; according to "Babington's Manual" 

 (1843) their angustifolium represents the type, and the other 

 is " elatius, Koch." Their Carex ccespitosa is C. Goodenovii > 

 Gay. " Molinia ccerulea, ft alpina, on the mountains of 

 Lewis and Harris," is not mentioned in the " Manual," but 

 according to Macreight 2 ft alpina M. alpina (Don) = M. 

 depauperata, Lindley ; but Don's name for it was " Melica 

 alpina." 3 In the last edition of the " London Catalogue " 

 we have two varieties named under Molinia, but not this 

 old one. Upon Langa they gathered " Thalictrum alpinmn^ 

 Arabis petrcea, Silene acaulis, Saxifraga stellaris, Oxyria 

 reniformis, Luzula spicata, amongst rocks on the summit 

 (2102 feet) Hymenophyttum Wilsoni, and on moist micaceous 

 rocks on the north-west side Saussurea alpina" 



The above seems to be the only station yet recorded in 

 the islands for Arabis petrcea. 



THALICTRUM MAJUS, Crantz. Mr. Ewing records this, giving 

 Babington as the authority ; but this record in " Top. Botany,"
