Much confusion has hitherto prevailed respecting the three 

 preceding species. Sir James Edward Smith appears to be the 

 only botanist who has examined, or even understood, the S. cym- 

 balaria and hederacea of Linnaeus ; the characters oi these he has 

 very considerably amended in his admirable Prodr ormis Flora? 

 Graca. The S. orientalis of Jacquin and Willdenow, given by 

 him as a synonym of S. cymbalaria, is a very distinct plant. All 

 three have a general affinity together ; but their characters are 

 abundantly distinct. The above descriptions of S.cymbalaria 

 and hederacea were taken from authentic specimens preserved in 

 the Banksian Herbarium, and were collected by the late Dr. Sib- 

 thorp during his travels in Greece*. 



* Specimens of Saxifraga hederacea, gathered lately in Crete by Dr. Sieber of 

 Praoue. are now in the Lambertian Herbarium.
