PRUNE&.—Amyegdalus nana. 
Loudon, v. 2, p. 673. 
Thrives very well here: we have several plants 
in various parts of the pleasure ground. Flowers 
regularly and plentifully in April. The flowers 
are very lovely, especially in the bud, a little 
before expansion, when they are of an exquisitely 
pure deep carmine; when fully expanded, their 
colour is a beautiful delicate rose, deeper than that 
of the peach blossom. I have never known the 
species produce fruit here. When im league 
appearance is very much like that of a miniature 
willow. 
The geographical range of Amygdalus nana 
is very carefully investigated by M. Alphonse 
de Candolle, in his Geographie Botanique Raisonée. 
It appears to be extensively spread through 
the southern parts of Siberia and of Russia, 
not further north than 51 degrees of latitude in 
the former country, and 54 degrees in the latter. 
From Russia it ranges south-westward into Tran- 
sylvania and Hungary, and its westernmost 
natural limit is on the frontier of Hungary and 
Austria, within a short distance of Vienna. 
A dry climate, and one of an extreme character 
—of great summer heat and winter cold—seems 
to be the best adapted to it: but in cultivation it 
bears very well our more temperate and cloudy 

skies.
