the two kingdoms. The pLant seems widely distributed in 

 Liddesdale, and evidently may be found from sea-level up to 

 the highest station, where I have found it about 1090 ft." 



In 1896 I found it twice at stations on the opposite 

 side of the river Liddel from those known to Mr. Elliot, 

 and, after identifying the plant, and finding it seemed to 

 be from the floras I had access to — a fairly common plant 

 in the Border counties, — I tliought nothing more about it, 

 until my friend the IJev. Dr. Paul asked if I had been 

 observing the plant, which was, he thought, of special 

 interest. After looking into the subject a little more, I 

 came to the conclusion that the Eev. Dr. Paul was right, 

 and that it was worth while making some further investiga- 

 tions, and it is with these I am troubling you on this 

 occasion. 



It is unfortunate that I have been unable to ascertain 

 the altitude of the Scottish stations at which the plant has 

 been found — although Watson mentions that it has been 

 found at 600 ft. — except, of course, where I have 

 observed it myself, and to which I will have to refer 

 further. However, as Solway Moss on the west side of 

 Scotland, and Blairdrummond Moss on the east side of 

 Scotland (Forth district), may be said to be both near sea- 

 level, it proves the plant to grow under conditions in this 

 country quite different from those in which it is found in 

 some other parts of the Northern Hemisphere, and this 

 aspect of the question requires to be mentioned. 



The stations at which I liave seen the plant in Liddes- 

 dale are on the following elevations: about 700, 800, 

 1000, and 1090 ft. above sea-level. 1 am informed by Mr. 

 John Elliot it begins flowering in April, and is perhaps 

 most easily seen towards the end of May, when it is in full 

 flower. Most of the flowering stems project a few 

 inches above the surface of the bog, which makes it visible 

 among the moss and heather. 



It appears to grow in patches, some of which are one or 

 more acres in extent. I have seen it flowering at the end 

 of May, and in October as 1 mention. I also found it in 

 fruit in August. 



About tlie miildle of last -June I visited the 1090 

 ft. station with some fiieiids, and, althouiih we searched
