It is seldom that a species of so obscure a genus as Draba 

 possesses such horticultural attractions as to claim a place in 

 the * Botanical Magazine ;' but such is the case with the pre- 

 sent plant, which is further very interesting on account of 

 its locality, for it attains almost as great an elevation on the 

 lofty Andes as any Phamogamic plant. It was discovered 

 by Humboldt and Bonpland near Quito, and has since then 

 been gathered repeatedly by Professor Jameson, of that city, 

 who sent seeds to his friend I. Anderson Henry. Esq., F.L.S., 

 of Hay Lodge, Edinburgh, and from whom living plants in 

 flower were received at Kew in March of the present year. 

 Professor Jameson describes it as of rare occurrence, and 

 growing in loose rocks and walls at elevations of 13-15,000 

 feet. It was figured by my father as long ago as 1837, in 

 the ' Icones Plantarum,' with the remark, u This would in- 

 deed be a lovely plant to introduce into our gardens."
