with these plants. They take up their abode in the same 

 way as the white scale, and if not speedily removed or 

 destroyed, soon make sad havoc. To put a stop to the 

 ravages of this pest, a wash should be given, as before 

 recommended, and after the soap has been rinsed ont of 

 the base of the leaf, a little tobacco powder should be 

 sprinkled into the hollows, and allowed to remain for a day 

 or two before brushing it off. This process will, however. 

 cause a somewhat dirty appearance, but it will ensure 

 ultimate health and vigour. Propagated by dividing the 

 plants.

n as it possesses * long slender-rooting stem, from different 

 parts of which arise small oral pseudo-bulbs, each bearing a 

 leaf ; a lesser leaf appears at the base of a bulb, and from the 

 axil of this the scape springs. It is a rather straggling but never- 

 theless beautiful species, and is tost grown fastened upon long 

 strips of cork, a little sphagnum being used in the operation ; 

 whSst, toprerent the plant getting too much "away from home," 

 the young growths should be twisted back as they advance, and 

 the practice continued until the pseudo-bulb is ultimately left 

 near the centre, or in any spot which nay appear bare. It likes 

 rtinat heat and a very moist atmosphere, when growing : but 

 durins the period of rest, it should be kept cool and dry. See

 and with Borage in cooling drinks: they are also put in 

 salads. The foliage only being useful, keep the flower- 

 spikes removed, as this tends to increase the luxuriance 

 of the plants. It thrives in any light soiL Propagated by

 oblong, covered by a three-valved succulent rind, contain-

.CEJE. An order of shrubs or trees, abound-

 of pellucid dots, and axillary and terminal fascicles of 

 flowers. Fruit indehiscent, somewhat drupaceous. The

BTJB.TOVZA (named after D. Burton, a plant collector 

 for Eew Gardens). OBD. Leguminone. A genus of hand- 

 some greenhouse dwarf Heath-like shrubs, natives of West 

 Australia. Flowers axillary, often thickly gathered at the 

 ends of the branches ; corollas rich purple ; keel generally 

 of a deeper colour, and the standard having sometimes 

 a yellow blotch at its base. Leaves simple or trifoliolate, 

 eessfle, usually awl-shaped. They thrive well in a mixture 

 of loam, peat, leaf soil, and sand, in equal proportions, with 

 thorough drainage; but care must be taken not to give 

 them too much water, as they require to be kept moderately 

 dry, and are difficult to preserve in a living state. Young 

 cuttings root freely in a pot of sandy soil, in a cool house, 

 with a bell glass placed over them ; but some of the species 

 produce seed in abundance, which are the best means of in- 

 creasing them.
