METER. An instrument for measuring the 
density of the atmosphere, and hence determining the pro- 
bable changes of weather, or the height of any ascent. To 
the gardener the Barometer is indispensable as a warning 
to take due precaution. 
BAROSMA (from barys, heavy, and osme, smell; re- 
ferring to the powerful scent of the leaves). The name of 
this genus is frequently incorrectly spelt Baryosma. ORD. 
Rutaceæ. Very pretty small, Heath-like, greenhouse ever- 
green shrubs, from the Cape of Good Hope. Calyx equally 
five-parted ; petals five, oblong ; stamens ten. Leaves oppo- 
site or scattered, coriaceous, flat, dotted, with their margins 
sometimes glandularly serrulated, sometimes almost entire 
or revolute. They thrive in a mixture of sand, peat, and 
a little turfy loam, with good drainage and firm potting. 
Cuttings, taken from ripened wood, planted in a pot of 
sand, and placed in a shady position in a cool house, with 
a bell glass over them, will root readily in a few weeks.

BARRED. Marked in spaces with a paler colour,

BARREN FLOWERS. The male or staminate 
flowers of many plants, such as the Cucumber, Melon, &c., 
are pop known as Barren Flowers, ie., they pro- 
duce no fruit. This condition is,in some similar 
to “blind ” Strawberries or “blind” Cabbages, so far as 
fruition is concerned, but stru and functionally it 
is widely different. The Barren Flowers of the Cucumber, 
Melon, &c., are produced by what are known as monæœcious 
plants, i.e., having male and female organs in different 
flowers, but on the same plant. In the Strawberry, &c., 
Barren Flowers are generally the result of unfavourable 
surroundings, or unskilful cultivation. A good example of 
Barren Flowers is seen in the ray-florets of many 
Composite plants, which are frequently really 
neuter, having neither male nor female organs. 
BARREN SOILS. A term signifying such 
The term can 
almost any soil may be rendered capable of afford- « 
ing a basis for some kind of vegetable life, arboli 
real or other. The question of planting up the 
enormous quantity of what is now waste land, might well 
engage the most practical consideration. Of course, the 
natural state of any land will, to a great extent, determine 
what would be its ultimate condition, after all that could 
be effected by mechanical agency has been accomplished. 
Drainage, irrigation, enrichment, pulverisation, are all 
matters which can only be considered upon a particular 
basis; but we doubt not that the thousands of acres of 
land now practically almost useless, might, by the adop- 
tion of proper means, be rendered fairly remunerative.

GTONIA (named after the Hon. Daines 
n, F.RS.). ORD. Myrtacem A genus of stove 
- evergreen ee, very difficult to cultivate. 
Flowers- large, racemose. Leaves opposite or whorled, 
generally obovate; margins ed or-entire. Fruit one- 
seeded, fleshy. They require a compost of two parts loam, 
one peat, and one sand. ~~ air should be given in abun- 
dance, and a moist atmosphere times maintained, the 
temperature ranging from 65deg. 95deg. Propagated 
by cuttings obtained from the lateral shoots; these, taken 
off at a joint when the.wood is ripe, planted in sand, with 
a hand glass ovpr them, root readily. The cuttings should 
not be stripped of any of their leaves.

BARROW. Garden Barrows are very numerous, both 
with and without wheels. The Flower-pot Barrow has a 
wheel and a flat surface, on which plants, pots, or leaves are 
placed, either directly, or, when small, in shallow baskets. 
The Haum Barrow is an open box or case, of wicker or 
other work, placed on, or suspended from, a pair of handles, 
with or without a. wheel, and is useful for carrying litter, 
leaves, &c. The Water Barrow, instead of a box, contains 
a barrel, tub, or cistern, in which fluid manure, or ordinary 
water, is conveyed to different parts of the garden. The 
Hand-barrow is a frame of wood, carried by two levers, 
which form four handles; for removing large pots or tubs 
of trees or shrubs it is very useful,

BARTONIA (in honour of Benjamin S. Barton, M.D. 
formerly Professor of Botany at Philadelphia). ORD. Loa- 
sacee. Hardy annuals or biennials, downy, with stiff and 
bearded hairs, This genus is now placed under Mentzelia in 
most standard botanical works. Flowers “ay yellow, 
large, terminal, expanding in the evening, w. are very 
fragrant, and becoming reddish as they fade. Leaves alter- 
nate, interruptedly pinnatifid. The species are very showy, 
and well worth growing. Any ordinary garden soil suits 
them. Seeds should be raised in a gentle heat in spring; =)
