size and colour of the flower will recommend it tor cultivation 

 in the greenhouse or temperate stove. It may possibly hear our 

 summers in the open air. We owe the introduction of this plant 

 to Mr. Nation, who has been long resident in Peru, and has col- 

 lected and studied the plants of that rich botanical region. It 

 is cultivated at Lima, but is a native of the Cordillera, and we 

 have the good fortune to possess in our Herbarium an unnamed 

 native specimen, collected by Mr. .Mathews in the Araancacs 

 (his n. 721).
