The genus jipse/zibrua/ithemum. with the exception of a few which are 

 'innuals, are all readily cultivated by cuttings, and the annual species by 

 seeds, which ripen freely, and should be sown as soon as they are ripe, in 

 pots of iinely-sifted hglit loam, well di'ained, and placed on a shelf, or 

 diw. au-y place in the Succulent house, till they come up and are fit for 

 potting into single pots. Cuttings may be taken clT at any period during 

 spring or summer, dried for a few days in a somewhat shaded place, and 

 dien planted in pots well di'ained and filled with a mixture of light, sandy 

 loam and hme rubbish. They do not require to be covered with bell 

 glasses, but are best placed on a cool, dry shelf, or in any dry pit where 

 they can be shaded for a few days until they begin to make roots. Young 

 wood, of com-se. should be chosen as emitting roots soonest, and that part 

 of the lirancli which contains the germinating bud. Most of them will 

 root in from tliree to live weeks, when they ai'e to be potted into small 

 pots, well drained, and in rich, hght loam, with a slight mixture of very 

 rotten dung. The first two sections, viz., Siilccaulia and Pdngentia. in 

 HawOith's arrangement of this genus, are so small, and being without 

 branches, can only be increased by dividing the whole plant : but this is 

 a matter of no great dirhculry. and only requires caution in the dissection, 

 so as not to occasion larger wounds than absolutely necessaiy. and also to 

 diy the chvided parts preriously to planting, as they are hable to rot, or 

 damp off.
