Cult. The greenhouse or New Holland species of Acacia 

 are the most ornamental of greenhouse plants in the winter 

 season and early in spring, bearing flowers from Christmas to 

 April. They are hardy and easily managed. The best soil for 

 them is an equal quantity of sand, loam, and peat. Cuttings 

 taken off by a joint from young wood, and planted in a pot of 

 sand, with a bell-glass placed over them, root freely. Some of 

 the kinds that do not strike readily by cuttings may be in- 

 creased by taking off pieces of the roots, planting them in the 

 same kind of soil as recommended for the plants, leaving only 

 their points above the surface, and then plunging them in a little 

 bottom heat. The greater part of the species might be propagated 

 by this means. The stove species are furnished with very ele- 

 gant foliage, but seldom flower in this country. Their culture 

 and propagation are the same as for the greenhouse species, 

 with the exception that they require more heat. The Acacia 

 Julibrissin, A. acanthocurpa, A. deciirrens, and A. moll'usima 

 are the only species that can be considered sufficiently hardy to 

 stand our climate in the open air, and these are liable to be in- 

 jured in severe winters, unless protected by mats. The best 

 situation for them is against a south wall, where they will make 

 a very fine appearance. They may be propagated either by 

 slips of the root or by young cuttings, planted in sand, with a 

 bell-glass placed over them. The surest way to raise all the 

 kinds is by seeds, when they can be procured.
