ends of very slender trailing slalks, produced in plenty on every side 

 the parent plant, as on the Cliilding Marigold. The flower-stalks 

 arise from the centre of these heads; are naked, about four inches 

 long, and lern)inated by close clusters of herbaceous flowers: the 

 leaves arc radical, forming roses, ovate, flesh}^ gibbous, even, sharp- 

 ish, ciiiate backwards, with cartilaginous, very slender hairs: the roo^ 

 puts forth lateral threads, which are filiform and decuml)ent, forming 

 runners at the end. It flowers sometimes in INfay, but usually in 

 July and August. 



Cnlture. — The fust tiiree sorts may be easily increased, by plant- 

 ing the cuttings of the stems and branches in the later spring and 

 summer months, after having been exposed in a dvy situation for a 

 few days, to heal over the cut parts, in pots filled with sandy earth, 

 plunging them in the bark-bed of the stove, or in a frame shaded 

 from the sun. When well rooted, they should l)e removed into sepa- 

 rate pots, and replaced in the same situations till fidly established, 

 when they may be removed into the greenhouse, where they should 

 have a sunny situation in winter, and but little water. 



The other species may be increased by planting the off-sets from 

 the roots in the same manner as above. 



As these are plants of a succulent nature, both in their stems, 

 branches, and leaves, as well as of curious growth, they aftbrd variety 

 among collections of other plants of similar kinds. They are capable 

 of bearing the open air in summer, in dry warm situations.
