The Greek speira, signifpng a cord, is consi- 
dered to be the foundation of the name of this 
genus, and to be applied in allusion to its general 
twiggy character. 
This hardy shrub is a native of the north-west 
coast of America, and the banks of the Columbia; 
where it is mentioned as growing with much greater 
luxuriance than experience would induce us to 
exp *ct. We have given its height as four feet, but 
its American height is stated at more than double 
that amount, and in the Birmingham garden Mr. 
Cameron observes that it promises to be of equally 
free growth, both in peat and loam. With us it 
has not, hitherto, grown freely; which, possibly, 
may have arisen from the presence of too much 
lime in the soil where it is planted; and the situa- 
tion being rather diy. 
We possess this plant through the kindness of 
Mr. Murray, Curator of the Glasgow Botanic Gar- 
den, who, we believe, raised it there from American 
seeds ; and has not failed to distribute it with the 
usual liberality which distinguishes that extensive 
and interesting establishment.
