Bossia a.—Leguminose.— Ever- 
green New Holland shrubs, which 
all thrive ina mixture of turfy loam, 
peat, and sand, well drained, and 
which m e propagated by cut- 
tings of the young wood. 
Boranic GarpEen.—A garden de- 
voted to the culture of plants with 
a view to botanical science ; and in 
which the plants are arranged ac- 
cording to some system, only one 
of a kind is planted, and a name 
appended to each. ‘The most con- 
venient mode for study is to place 
the plants in straight rows of nar- 
row beds, one row in a bed, with a

freely in loam and peat in a warm 
situation in the open air, or in a 
greenhouse ; and it is creased by 
cuttings of the roots. B. versicolor 
has fine red flowers and is very 
ornamental, though it is more tender 
thau B. triphy'lla. 
Bowers.—Slight arbours, formed 
by training climbing shrubs over 
trellis-work so as to form 2 covered 
seat. They only differ from arbours 
in being less closely covered. See 
ARBOURS. 
Bo'x-TreeE.—See Buxus. 
Box-epeines.—The kind of Box

groups of one order, tribe, or genus | 
in a group. ‘These groups have 
the best effect when of a circular | 
form, and when placed on a lawn. 
The position of the groups rela- 
tively to each other should be such 
as to correspond with the botanical 
system followed.

heat is often very useful in enabling 
hothouse plants to stand in the 
open air during summer. A _ bed 
may be formed of bark, decayed

the pots may be plunged, and the , 
surface covered with a thin coating |

incéna.— These splendid flowers are 
biennials, and their seed should be 
sown early in May, in a border of 
light sandy soil with an eastern 
exposure, and never in front of a 
hothouse or south wall, as they 
cannot bear too much heat. The 
seeds should be sown very thinly in 
narrow drills, made about six inches
