BERTOLONIA. 
Greenhouse and Stove Plants.

last for several years, increasing in size, 
requiring larger pots, and bearing pro- 
portionately more flowers. When it is 
desirable to increase any sort by cut- 
ings, these can be made of the shoots in 
pieces about 3 inches long; inserted in 
sand, kept moist, moderately close, and 
shaded in a temperature of 60°, they will 
root ; then pot singly, and treat as advised 
for the seedlings while at a corresponding 
size. If desired these Begonias can, when 
strong, be kept on flowering through a 
good part of the winter. 
Like Gloxinias, Petunias, and some other 
softwooded plants, the strains of which 
have been so much improved, there is an 
almost endless number of good varieties in 
cultivation. 
The foliowing are all fine sorts :—

Insects. — These Begonias are little 
Rose, shaded pur- 
troubled by insects; for thrips, which 
sometimes establish themselves on the 
undersides of the leaves, syringe freely 
with clean water. 
BERBERIDOPSIS CORALINA. 
An evergreen plant with pretty red 
flowers, sometimes used as a greenhouse 
climber. From Chili. 
It is increased by cuttings struck in 
spring in moderate heat, and grown on 
with the usual greenhouse treatment until 
large enough to plant out, when it should 
have a well-prepared bed of open peaty 
soil. 
InsEcts.—The plant is subject to red 
spider, the best means of keeping which 
in check is a free use of the syringe daily 
through the growing season. 
BERTOLONIA. 
These small-growing stove Melastomads 
almost vie, as regards beauty of leat- 
marking, with the most charming of the 
variegated Orchids. They are natives of 
the hot countries of the East, and to grow’ 
them well and bring out and preserve 
their leaf-marking a high temperature is 
required. They are plants of quite a soft- 
wooded character, and do not grow to a 
height of more than 6 or 8 inches. They 
strike freely from cuttings made from 
shoots in a half-solidified condition. They 
may be struck at any time when obtainable 
in that state, but are most likely to be in 
proper condition in spring. Lach cutting 
should consist of at least a couple of joints. 
Put them in small pots singly in sand, and 
cover them with a propagating glass, but 
do not keep them so close as to cause 
damp, as soft growth of a nature such as 
these, if too close and moist, is lable to 
rot. Give as much water as will prevent 
flagging, keep in a warm stove temperature, 
and shade when the sun renders this 
necessary ; they will soon make roots, when 
they should be given more air, and, as they 
get established, be removed to larger pots. 
The soil best suited to them is fibrous peat 
mixed with some sphagnum, sand, and 
crocks. A temperature of from 65° to 70° 
in the night during the growing season, 
with a rise by day proportionate to the 
warmth of the weather, will answer; 60° 
by night, with 5° or 10° more in the day, 
will do for the winter. Some growers 
keep the most delicately marked kinds 
almost wholly covered with a bell-glass, as 
Ancectochili are sometimes grown, but this 
treatment makes the plants very soft and 
tender ; yet they do not do well if placed
