 structi : laciniae ovato-oblongre, obtusae, carnosa?, obso- 

 lete trinerves. Petala obovata, calyce duplo longiora,

I have reduced to this plant the Saxifraga intricata and mixta 

 of La Peyrouse, and the pubescens of Poiret, as neither of them 

 affords sufficient or permanent characters to establish them as 

 distinct species. It varies much in size and in the number of 

 the segments of its leaves ; and likewise in the number of flowers 

 on a stalk ; but its prominent features are always the same.
