 Range of mean annual temperature 49 — 46 (43?) 

 Native. Rupestral, &c. These were given under one 

 name (H. rigidiun) in the first edition of Babington's Ma- 

 nual of British Botany ; but in the second edition of the 

 same work, the name of tridentatum supplanted that of 

 rigidum, for the more frequent and (as previously held) 

 more typical form of H. rigidum of the first edition. Of 

 course, it becomes now impossible to make out which of the 

 two alleged species may be intended by botanists who re- 

 cord localities for " H. rigidum." Whatever may be the 

 result of his investigations ultimately, I fear that the imme- 

 diate effect of Mr. Babington's added species (or rather, 

 added names) in our lists of British Hieracia, will be that 

 of increasing the confusion and en*ors respecting their lo- 

 calities. It is highly probable, not to say certain, that 

 some of Mr. Babington's novelties in this genus are really 

 other names for Smith's species; and as the latter have 

 been still retained, ambiguity and confusion are inevitable. 

 Moreover, as neither the names nor the species of the 

 second edition of the Manual correspond with those of the 

 first edition, there is another prolific source of error and 

 cross-naming introduced into this genus, which, like its 

 geogi-aphically natm-al associate ' Salix,' has been rendered 

 botanically odious by books.
