ADDITIONAL NOTES, ETC. 4G1 



Mr. Syme, who found this species in Orkney. The area 

 thus becomes " general." The latitude may not actually 

 exceed the line of 59, although in conformity with the 

 explanation before given, on page 60 of volume first, the 

 range of latitude should now be entered as 50 — 60. 



648*. Senecio aquaticus, vol. ii. p. 116. (No. 648, b.) 



This aj)pears to me quite distinct from S. Jacobsea after 

 experimental cultivation under various changes of soil and 

 moistiu'e. Independently of the less conspicuous charac- 

 ters, the loose and spreading ramification of this species, 

 contrasted against the closer and more corjTnbose inflo- 

 rescence of S. Jacobasa, will afford a diagnosis at the 

 distance of many yards. 



Xd. Senecio erraticus, vol. ii. p. 117. 



In reference to this plant, and to S. barbar^efohus al- 

 luded to on page 115 of volume second, Mr. Babington 

 writes thus ; — " Senecio barbarsefolius (Reich.), I beheve, 

 with Koch, to be the lai'ge form of S. aquaticus, which I 

 formerly mistook for the S. erraticus (Bert.), but do not 

 now distinguish specifically from S. aquaticus. I have 

 never seen the true S. erraticus in Britain." (Bot. Gaz. 

 ii. 9). 



649. Senecio paludosus, vol. ii. p. 118. 



It appears now veiy doubtful whether this species still 

 remains in om* flora. Mr. G. S. Gibson writes of it, — 

 " This I believe to be now quite extinct in Britain ; having 

 been so in the fens of Cambridge many years, and sought 

 in vain in Lincolnshu'e by my friend E. Forster. I doubt 

 its having been gathered by any living botanist." 



651. Cineraria palustr is, vol. ii. \). 119. 



Mr. Pascoe adds Cornwall to the list of coimties that 

 have been reijorted for this species ; I know not upon 

 whose authority.
