here a complete reform of the whole Genus, 

 from 233 to 203.

 ris. Habitus Varuis, fol. sepe crassis. — The 

 free pistil Sp. arc the types of the G. and family 

 Saxifragea, along with Mitdla,, Tiarella &.c. 

 the Sub-Gen. Hirculus. Hijdatica, Arabidia, 

 Micranthes Tausch, chiefly belong here, and 

 only apply to the habit. Necker called Hi/daticn 

 all these true Saxifragas ; but I shall confine it 

 to the next Genus. The Sp. belonging here are 

 Sax. aspera, bryoides, media, cernua, sibirica 

 rotundifolia, spicata. arguta, nelsoniana, 

 nudicaulis, nivalis, vernalis, virginiensis, in- 

 tegrif, dahurica, flagellaris ^'C. but many 

 must be examined again. Sax. orientalis Jaq. 

 Vitm. or Sax mollis b. aiu only differs by petals 

 trinerve, perhaps type of a subgenus Blalagea 

 Raf. it is ih^Geam orientale Tourn it. 2 ic 148. 

 Caule procumb, stolonif. fol. lobatis, pet. obov.

 subrot. enervis glandulis vel pustulis nullis — 

 Type Saxifraga, hederacea, but others may 

 perhaps belong here also. This G. must go into 

 nat. fam. Diceracea, with the next.
