6 ADDRESS OF THE EDITOR. [January, 



grew there for at least a few years, — the reporter did not learn 

 how many, because there was no one there who knew. It must 

 be accepted, like the Aremonia agrimonioides, which is not con- 

 fined to a single spot in Scone Woods, but grows in various 

 parts of the carse, though probably not in very great force. 

 This latter plant, it will be seen from the Thirsk Report, has 

 turned up in West Yorkshire. 



But if the new plants from Perth be few, the new stations 

 recorded for some of the rarest of our favourites are numerous. 



In the first place, we have to congratulate Mr. Sim on the 

 discovery of a new locality for LinrKsa borealis. This is one of 

 the most interesting facts which has ever been published in the 

 ' Phytologist.^ 



Cheiranthus Cheiri, Sedum album, and S. dasyphyllum (they 

 are here combined because mural plants) have been found by 

 Mr. Sim growing on the living rock, not on the dead brick or 

 stone wall only. Our correspondent who sent a long list of 

 Cheshire plants, saw it (the Wallflower) growing on the rock 

 on which Beeston Castle stands, or rather stood. But in this 

 case it may probably be truly said that the seeds dropped from 

 the wall upon the rock, and there they grow. Is there an old 

 castle or the remains of an old wall on the top of the rock by the 

 river Tay, where Mr. Sim finds the Wallflower in such abun- 

 dance ? If there be not, how did it get there ? By currents ? 

 Does the flood in the river ever rise so high as that part of the 

 rock where the plant grows ? Might not the birds have conveyed 

 the seed? These are foolish or at least unprofitable questions, 

 because no satisfactory answer can be given to them. The two 

 Sedums have rarely or ever been seen so far north as Scotland. 

 They have both an extensive European range, especially S. album. 

 Probably both might appear on natural stations in the South of 

 England, if rocks were as common as brick walls and tile roofs. 

 As it is, S. album occurs many times more frequently than S. 

 dasyphyllum, which is one of the rarest of our rare plants. 



Corydalis lutea is also recorded from a wall at Scone toll-bar. 

 Last summer, while residing for a few days at Eoot's Cray, in 

 Kent, I saw this plant in several places spreading from the gar- 

 dens, where it was planted, and creeping over the shingly path. 

 I did not see any of it on walls here, but abundance in the 

 cottage gardens, where it grows luxuriantly. Few plants have
