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 out 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

BURNET (Poterium Sanguisorba; from poterion, a 
cup; being used in cooling drinks). ORD. Rosacee. A 
native perennial. The leaves are sometimes used in soups, 
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. Tt thrives in any light soil. Propagated by 
division.

Pittosporacee. A handsome, much-branched, greenhouse 
evergreen shrub, forming a very pretty object when covered 
all over with its elegant white blossoms. It thrives well 
in a compost of sandy loam and peat, in equal proportions. 
Young cuttings will root freely in sand, under a bell glass, 
with a little bottom heat.

BURSERACEÆ. An mir shrubs or trees, abound-

of pellucid dots, and axillary and terminal fascicles of 
flowers. Fruit indehiscent, somewhat drupaceous. The 
genera best known are Amyris, Balsamodendron, Boswellia, 
Bursera, and Canarium. 
BURTONIA (named after D. Burton, a plant collector 
for Kew Gardens). Orp. Leguminose. 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, 
sessile, 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 
cu 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.
