is oue of the best flowers to sow in the neighbourhood of bees, 

 for it is said they derive more nourishment from it than from 

 any other flower that blows. Good garden soil. Propagated 

 l)y seeds, which may be scattered over the surface and raked 

 iu, and the plants afterwards thinned where they are too much 

 crowded. The perennials maybe multiplied by parting the roots. 



BORBONIA. [Leguminosse.] Greenhouse evergreen 

 shrubs, with papilionaceous flowers. Not very common. 

 Soil, peat and loam. Propagated by cuttings in sand under 

 bell-glasses. 



BORONIA. [Rutacese.] Beautiful evergreen greenhouse 

 shrubs. Soil, sandy loam one part, and turfy peat two parts. 

 Propagated by cuttings of the ends of the shoots, planted 

 iu sand under a bell-glass. The glasses will require to be 

 wiped diy every morning, and when the cuttings begin to 

 grow they may be removed an hour every day. The cuttings, 

 when struck, should be planted singly in three-inch pots, 

 one-third of the pots being filled with broken crocks, or pot- 

 sherds, to secure good drainage ; and as these small pots are 

 filled with roots they may be exchanged for larger ones. If 

 the object is to keep the plants short and bushy, take the 

 top off to encourage lateral shoots, and as these get long top 

 them also ; but they naturally grow very handsome and pyra- 

 midal, with enough lateral shoots to form handsome, well- 

 proportioned shrubs. The plants must have plenty of air in 

 mild weather ; but if set out in summer with other greenhouse 

 plants, and neglected, they are apt to become discoloured in 

 the foliage, which is rarely recovered. They are, in fact, as 

 miffy as heaths, and if the watering be neglected, the effect 

 is almost immediately seen. One watering too many is 

 pretty nearly as bad as one too few ; therefore they ought not 

 to be watered by rule, but examined every twenty-four hours, 

 and if they are damp they require no watering that day ; if 

 otherwise, they do require it. When they are watered, all the 

 compost must be wetted — not merely half an inch of the top, 

 for that is useless. B. alata, flowers rose colour. B. Drum- 

 monclii, flowers pink. B. serrulata, flowers rose pink. B. 

 tetrandra, flowers pale purple. B. triphylla, flowers pink.
