In the Old World we have only one species of Erj/thro- 

 liium. For a long time three distinct species, with several 

 vaineties, have been known in America. In 1871, Dr. 

 Asa Gray described the curious E. propnUans from Minne- 

 sota, and last year Dr. Sereno Watson added three new 

 species, the present plant, E. Howellii and E. citrinum, 

 described from material obtained in Oregon by Messrs. 

 Howell and Henderson. All the eight species are quite 

 hardy, and resemble one another closely in habit and 

 general appearance. They differ widely in the colouring 

 of the flower, and in this respect the present plant comes 

 nearer to the old European type than any of the others. 

 Our drawing was made from a plant that flowered at Kew 

 last April, which was obtained from the Harvard Botanic 

 Garden.

 ing faintly-scented flowers. Perianth campanulate, about

 purple at the base, the outer broader than the inner, and
