312 ADDITIONAL SPECIES, ETC. 



duce likewise a sort of running commentary upon the two 

 preceding volumes, over and above the addition of the 

 new and subdivided species to be first more formally 

 treated. Accordingly, such a commentary will follow the 

 " Additional Species, &c." in the after part of the present 

 volume. 



t Ranunculus confusus, " Godr." 



Area 1***50****11** 14. 



South limit in Somerset, ? 



Noi-th limit in Haddington, ? 



Estimate of provinces — ? Estimate of counties — ? 



Latitude 51 — 56. English (?) type of distribution. 



Agrarian region. Inferagrarian — Midagrarian zones. 



Descends to the coast level, in the Peninsula. 



Ascends scarcely, or not at all, above the coast level. 



Range of mean annual temperature 50 — 48, 



Native. Lacustral, Sub-littoral. Very closely resem- 

 bling E. aquatilis, and hitherto doubtless passed over by 

 collectors as one of the varieties of that proteiform sj)ecies. 

 There are, however, some distinctive characters ; and their 

 existence induces me to give the plant a separate formula 

 here, although quite unprepared to show its distribution 

 in a satisfactory manner. My herbarium at present con- 

 tains specimens from Haddington only, collected by Mr. 

 J. T. Syme. To this county Mr. Babington adds also 

 those of Somerset, Gloucester, Monmouth (Mr. Hort), 

 Pembroke and Durham (Mr. Hort). These distant sta- 

 tions give probability that R. confusus will be found in 

 many intermediate counties along the coast line, and pos- 

 sibly more northward than Haddington.
