in heads with an enormous number of stamens, which are the prin- 

 cipal attraction. 



Propagation. Take cuttings in February. 



IXORA. This is hardly a genus for the florist to deal with, as 

 the plants take more care than the prices obtained for them would 

 permit. There are numerous species and varieties, all of which are 

 attractive when well done. In the latitude of Washington, D. C, 

 they make growth best when plunged outside, and some of them 

 flower profusely out of doors. /. Colei is a good white; /. Williamsii, 

 I. coccinea and I. Chelsonii are all very reliable species. 



Culture. They wiU thrive in the warmest house during Win- 

 ter. Peat, sand, and a little loam will make a suitable soU. 



Propagation. Cuttings should be put in during March. 



JACOBINIA (Libonia). This is a charming Winter-flowering, 

 dwarf evergreen shrub. The species, /. penrhosiensis , is one of the 

 commonest Jacobinias grown. 



Culture. Its culture is of the easiest description, and almost 

 any soU will suit the plant. They are suited to conditions for grow- 

 ing Begonias. 



Propagation. Put cuttings in the warm propagating bed 

 during the latter part of February; plant out middle of May to make 

 growth; lift middle of September and flower in a moderately warm 

 greenhouse. 



JASMINUM (Jasmines). Although there are other meritori- 

 ous species, /. grandiflorum, primulinum and nudiflorum are the 

 ones usually grown. 



Culture. Plant out the young stock in May, and by the end 

 of September they should be lifted and potted. Keep in an inter- 

 mediate house. The plants will stand full sunshine, and are of easy 

 culture. 



Propagation. They may be propagated either by layers or 

 cuttings of nearly mature wood. 



KENTIA (Howea). Two of the best kinds are Kentm Bel- 

 moreana and K. Forsieriana; they are useful either for house plants 

 or decorating. When they reach a desirable size they should be 

 kept on the cool side, as they wfll then be less liable to injury when 

 used. (See also Palms.) 



L.iELIA. Lcelia anceps, the principal species, makes its growth 

 from April onward. It is an abundant bloomer, but on account of
