A native of elevated dry 



in New Sp 



near 



Totoniho el grande ; also of the mountains of Mexico, near 

 Tlalpuxahua, whence it was introduced by Mr. Graham. 



It proves a very pretty perennial, growing about 2 feet 

 high, and producing its deep pure blue flowers in July, 

 August, and September. In the summer it thrives in the 

 open air, forming a pleasing contrast with the red Brazilian 

 and Mexican species commonly cultivated ; but in the 

 winter it is necessary to preserve it from frost in a 

 house or well-protected pit.
