On the First Eecorded Occurrence of Chara Baltica 

 IN Scotland. By F. C. Crawford. 



(Read 8th November 1900.) 



Oa 31st August 1900, when looking for plants in Loch 

 Stennis, in Orkney, I pulled up a lot of a Chara which was 

 new to uie, and I sent it to Mr. James Groves, who replied 

 that it was Chara Baltica, Bruzel, and that this was the 

 first record of its having been found in Scotland. 



Mr. Groves pointed out that this Chara is a different 

 form to that of var. affinis, which is an extreme form, 

 closely bordering on Chara hispida, whereas the Loch 

 Stennis plant is much more like the Scandinavian plant. 



Mr. Groves also points out " that if you examine the 

 cortex you will notice that the primary series of cells are 

 slightly the more prominent, so that the spine-cells do not 

 appear to be in furrows, as in the vulgaris andhispida section." 



The above micro-photograph shows the uniformity of 

 size ill the cortical cells, and the absence of ridges which 

 characterise the vulgaris and hispida sections.
