 nelled, entire, linear, acute, the radical leaves 3-5

ORDER CRASSULACE.* 



Orpine Stone-crop or Roseroot (Sedum Rhodiola, 

 D.C. =5. roseum, Scop.). The habitat of this plant 



is moist alpine and subalpine rocks, and sea cliffs. 

 The plant has the rosette habit. The rootstock is 

 thick, cylindrical, fleshy, branched, woody, stout, 

 perennial, smelling of roses. The stems are annual, 

 simple, fleshy. The buds are scale -like. The 

 leaves are bluish-green, fleshy, inversely ovate, 

 lance-shaped, alternate, oblong, smooth, above 

 larger and crowded, acute, toothed at the apex.
