A very ornamental, hardy perennial, flowering abundantly 

 in September and October, in the open air, and forming a 

 very valuable addition to the list of available border plants. 

 It is a native of Japan, where it was discovered by Thunberg 

 ninety years ago, and was introduced into Kew by Mr. 

 Oldham, collector for the Royal Gardens, who, after making 

 many valuable botanical collections, perished of fever on the 

 coast of China. As a species it is very nearly allied to the 

 H. uralum, Hamilton, of Nepal (Tab. nost. 2375), and will 

 probably prove to be a large-flowered variety of that plant. 

 It is very variable in the foliage, which is flat or has recurved 

 margins, and is green or rust-coloured beneath. 



Descr. A small, perfectly glabrous, slender, branching 

 shrub, one to" three feet high. Stems and branches terete, red.
