 mountains. Height 6 ft. to 10 ft ; in British gar-

This plant was raised in the Hort. Soc. Garden, 

 and has proved quite hardy. The leaves are dis- 

 tinctly marked with glandular dotting ; a very un- 

 usual case among leguminous plants. The twigs 

 are short, and so closely set upon the branches 

 as to form a dense mass of foliage. Each is termi- 

 nated by an erect compact spike, from 2 in. to 

 3 in. long, of white or pale yellow flowers, 

 which, although not larger than those of a spiraea, nevertheless, from their 

 abundance, must produce a beautiful appearance. (Bot. Reg.
