Cult. These plants succeed best in a light sandy soil, in moist 

 shady situations. They may be either increased by dividing the 

 roots, or by seeds. The D, bulbifera may be encreased by the 

 bulbs which grow in the axillae of the leaves. They are all or- 

 namental plants, and deserve to be cultivated.

Cult. The species of this genus are well adapted for orna- 

 menting rock-work, but as they are very rare and apt to be killed 

 in the winter, we therefore would recommend a plant or two of 

 each to be planted in pots, and placed among other alpine plants. 

 A mixture of sand, loam, and peat will answer them well ; the 

 pots which they are planted in should be well drained with 

 potsherds. They may be increased by dividing the plants at the 

 root, but more readily by seeds or by young cuttings.
