species of Willow-herb (Epilobium), the Primrose- 

 tree (CEnothera), the Enchanter's Nightshade (Circcea): 

 and in warm countries, the Sanders (Santaluiri) , &c. 

 The native country of this Order is in the region of 

 the 40th degree N.L.

 itself, in the vicinity of the snow-line, in some herba-
