farinaceous Albumen. Stem herbaceous, or some- 

 what shrubby. Leaves opposite or alternate, succu- 

 lent." 



Tilfaa, Crassula, Cotyledon, Rhodiola, Seclum, Sem- 

 pervivum, fig. 242, and the variable genus Septas, per- 

 haps not distinct from C?^assula, are all Jussieu's cer- 

 tain genera ; Petit horum being placed at the end, as 

 their ally. This last however is as genuine a specimen 

 of the Order as any of them, the Capsules being only 

 more united into one, opening at the inner margin of 

 each cell, as in the rest, and by no means circumscisstf, 

 or bursting all round, as the author, by some accident, 

 has been led to suppose. The Petals are often partly 

 or entirely wanting, in which case the segments of the 

 Calyx become multiplied. 



Ord. 84. SAXIFIIAGJE. " Calyx either superior, or 

 more frequently inferior, in 4 or 5 segments. Petals 4 

 or 5, rarely wanting, inserted into thq upper part of 

 the Calyx, alternate with it's segments. Stamens as 

 many, or rather twice as many, inserted into the same 

 part. Germen simple. Styles and Stigmas 2. Fruit 

 often capsular, many-seeded, of 1 or 2 cells, opening 

 at the top with 2 valves, whose inflexion forms the par- 

 titions. Embryo incurved, surrounding a farinaceous, 

 or somewhat solid, Albumen. Stem usually herba- 

 ceous. Leaves alternate, rarely opposite, occasionally 

 rather succulent." 



Sect. 1. Fruit superior, capsular, with 2 beaks at the
