CRUCIFERZ. XXXIV. Eropuita. 
many of them are apt to damp off in the winter in this kind of 
situation, unless taken great care of, therefore the safest way 
to preserve them is to keep a plant or two of each of the 
perennial kinds in small pots among other alpine plants; they 
thrive best in a mixture of sand, loam, and peat, and the pots 
should be well drained with potsherds ; they are easily increased 
by dividing the plants at the roots, or by seed. The annual and 
biennial kinds, having rather a weedy appearance, are only fit for 
botanic gardens ; they should be sown in the open border or on 
rock-work. D. nemordalis and D. murdalis require to be sown in 
a shady situation.

Cult. These pretty little annual plants should be sown in the 
autumn in the sunny parts of rock-work, where they should be 
allowed afterwards to scatter themselves. Being very early 
flowering plants, therefore very desirable.

radical ones usually stalked; cauline ones often auriculately-
