This is a very pretty little shrub, producing in abundance 
_ its small, rosaceous, white blossoms ; its erect, rigid stem, 
and arched branches, forming a neat round bush, and fitting. . 
it for cultivation along with the smaller ornamental species 
of Cistus. The flowers appeared in succession in the open 
border at the Botanic Garden, Edinburgh, during August 
and September. ‘The species is a native of Siberia, and is 
stated by Mr. Loppices to have been received by him from 
Mr. Buscu of St. Petersburg in 1822. The difficulty of 
propagating it, noticed by Mr. Loppiezs, is probably the 
reason why it is so seldom seen in collections.
