440 Mr. D. Don's Monograph of the Genus Saxifraga. 



Obs. Prcecedenti valde affinis, sed satis differt : humiliore 

 et densiore, surculis vix ullis, foliis lanceolatis breviori- 

 bus crassioribusque apice obscindente-obtusis, laciniis 

 calycinis brevibus late-ovatis, petalis ovalibus integris : 

 nervis fusco-rubris, filamentis purpureis, antheris fulvis. 



Mr. Haworth first distinguished this species in his Miscellanea 

 Naturalia, and gave it the very apt name which it now bears. 

 This plant is given in English Botany as a British species, and, on 

 the authority of the late Mr. James Donn of Cambridge, is said 

 to be a native of Scotland : but some other plant must have been 

 intended ; for I doubt much whether the present has been ever 

 found any where in Britain. In Scotland I am certain it has not.
