A native of Mexico, found by Humboldt and Bonpland 

 in cold stations on the slope of the snow-capped mountain 

 of Toluco, at the height of 10,500 feet above the sea ; flower- 

 ing in September. Specimens of it were sent me by Mr. 

 Groom, of Walworth, in September last; the plant had 

 been obtained from Belgium. 



It is a very ornamental and nearly hardy perennial, growing 

 about three feet high in any rich garden soil, flowering freely 

 from the end of June to September, and requiring the same 

 treatment as P. atropurpureum and pulchellum. Like most 

 of the Mexican species it seeds freely ; the seeds should be 

 sown about the middle of May, on a bed of light rich soil 

 (covering the seeds with a little sandy peat) in the open 

 border, but not fully exposed to the mid-day sun ; the plants 

 will be fit to pot in the autumn (September), and should be 

 kept in a cold pit all the winter; they should be planted out 

 where they are to remain about the middle of April. The 

 plants will stand out all the winter unprotected, but generally
