ARABIS PETRA hastulata. 
. Order. 
TETRADYNAMIA SILIQUOSA,” 
Following M. De Candolle, we place this 
pretty little plant to Arabis instead of Car- 
damine, with which it formerly stood. It 
is a native of the North of Europe, and 
grows on rocks, forming a little tuft of 
leaves, surmounted by flower stems, which 
are seldom more than an inch or two in 
height : they are produced in May or June. 
The plant is rather difficult to keep: 
it requires no shelter, and succeeds best in 
a small pot, in light loam. The roots may 
admit of separation occasionally for in- 
crease.
