For this very rare plant, native of the rocks on the higheft 

 mountains of Auftria and Stiria, we are indebted to our old 

 friend Mr. Loddiges, in whofe garden at Hackney we have 

 obferved it in flower, for thefe two or three fucceffive years. 

 The tridentata of Hortus Kewenfis has been fometimes miftaken 

 for this, but is eafily diftinguifhed by its ternate leaves, and by 

 the teeth at the end of the leaflet, which are ufually three in 

 this alfo, being more obtufe. 



The flowers in Potentilla clufiana are large in proportion 

 to the plant, obfoletely obcordate ; the alternate laciniae of the 

 calyx broader, more hairy, and of a dull red colour ; filaments 

 and ftyles at firft white, but changing red. From P. caulefcens 

 it appears to be chiefly diftinguifhed by its more diminutive 

 ftature, petioles fcarcely equalling the leaf, flowers larger and 

 fewer, and by the number of teeth at the end of the leaflets, 

 which are ufually three or five in clufiana, but feveral in cau- 

 lefcens. The latter, although more common in Auftria, has not, 

 we believe, as yet found its way into our gardens.
