B. pinnata. This is the best of the 
Boronias, as well as one of the most de- 
sirable plants in cultivation. It is a good 
grower, flowers freely, and with good treat- 
ment will last for many years. We have 
seen a plant of this variety in a 15-inch 
pot for seven years, flowering every season 
regularly, and in as good and healthy a 
condition at the end of that time as it was 
at the commencement. 
B. serrulata. This is a smaller-grow- 
ing different-habited plant, flowering 
altogether from the points of the shoots. 
It has bright-coloured flowers, highly 
fragrant, a small plant being suflicient to 
perfume a plant-house or large exhibition 
tent. It flowers usually in April, May, 
and June, lasting eight weeks in bloom. 
Insects.—They are all subject to brown 
scale and aphides, their small leaves render- 
ing it difficult to remove the former insect. 
The bestremedy isto wash themall over with 
insecticide, laying the plants down on their 
sides during the operation, which should 
be done as soon as they show signs of com- 
pleting their growth, before the flowers 
show prominently, otherwise the washing 
may cause them to drop off. For aphides 
fumigation is the best course to follow, 
‘ smoking them two or three times at in- 
tervals of ten days. They are more or less 
subject to mildew at all times of the year, 
but especially during the winter and 
spring, particularly if kept in too low a 
temperature. They must be looked over 
often, and sulphur carefully applied as 
soon as the least trace of the parasite is 
discovered, for, if neglected, they will 
quickly lose quantities of their leaves, and 
this has a serious effect upon the roots. 
Allow the sulphur to remain on three or 
four days, then syringe clean off, being 
careful that none gets into the soil, or it 
will endanger the health of the plants. 
BOUGAINVILLEA. 
These are amongst the very finest stove 
plants in cultivation, especially for cover- 
ing a back wall or training on a roof, 
where, if the long drooping branches are 
allowed sufficient freedom, they have a 
charming effect ; when well managed they 
are scarcely surpassed by any plants in 
cultivation. B. glabra is the freest-flower- 
ing of all the species, blooming well 
even in a small state, and when it has 
room enough to attain a considerable size 
it will keep on for most of the summer. It 
is the best of the family for pot culture, to 
which purpose it is particularly adapted, 
either for the decoration of the stove or for 
the exhibition stage. A description of the 
growth and flowers of this species (which, 
for its general properties, is the best to 
grow) will suffice for the others, as they 
only differ, so far as the purposes of culti- 
vation are concerned, in the strength of 
growth and depth of colour in the flowers. 
Bougainvilleas are very distinct from all 
other cultivated plants, especially in the 
general appearance of the flowers. These 
are somewhat small and inconspicuous, in 
form not unlike the individual florets in 
a Lantana; they are inclosed in large 
bracts, which, while small, when they 
first appear, are green, almost the colour 
of the leaves. As they approach their 
full size, about an inch and a half in 
length by an inch in breadth, they, 
however, assume a beautiful pale mauve 
colour which lasts with little change for 
several weeks, the strong shoots producing 
a succession opening for a considerable 
time. As fresh growth is made through 
the summer, the flowering is prolonged 
with little interruption until autumn, 
especially when the plants are grown in 
a brisk heat. There is one peculiarity 
about the species, that it will flower pro- 
fusely in a cool intermediate house when 
planted out, but rarely makes much bloom 
when its roots are confined in a pot, unless 
it is grown in a higher temperature. It 
also gives a much longer succession of 
flowers when in a warmer situation. The 
flowers of all the species have few equals when 
cut for filling large vases; they are equally 
suitable for bouquets, lasting longer, with 
little or no moisture to support them, than 
most things. They are all strong growers, 
and require a considerable amount of root- 
room to enable them to make growth 
sufficiently to show their true character ; 
they will thrive in either peat or loam, 
but the latter appears to suit them best, 
as it does not so soon become exhausted. 
B. glabra does not require a long rest in 
winter, and may be started early in the 
year. From plants so treated cuttings 
may generally be obtained by the be- 
ginning of March. These should be taken 
off with a heel as soon as they are 6 inches 
long, and inserted singly in small pots 
filled with three parts fine loam to one of 
sand, with a little drainage ; cover with a 
propagating glass, and place in a night 
temperature of 70°, allowing it to rise 8° 
or 10° with sun-heat. Keep moist and 
shade from the sun; they will root in a 
few weeks, when they may be moved into 
6 or 7 inch pots, mixing one-fifth rotten 
manure with the loam, and as much sand 
as will keep. the soil sufficiently open to: 
allow the water to pass freely through it.
