Linn. 14, Or. 2, Nat. Or. Verbenacea. These plants 
are rapid growers, forming small bushy shrubs, 
and producing their pink, yellow, orange, or 
changeable-coloured heads of flowers in great 
abundance, which have a somewhat agreeable 
aromatic flavour. Any loamy soil suits them ; and 
they are increased readily Iw cuttings in sand, in 
heat. Synonyme: \. parvifaiia.

Larch, see Ldrix. 
Larix, Decandolle. From tne Celtic, lar, fat ; on 
account of the tree producing an abundance of 
resin. Linn. 21, Or. 10, Nat. Or. Conifera. All 
the species of this genus are highly ornamental, 
and some of them are extensively cultivated for 
their timber, which is adapted to a variety of use- 
ful purposes. The larch grows rapidly in almost 
any soil, and in any situation, yet its timber can 
only be brought to perfection when the trees are 
grown in a clear drj' atmosphere, on a celd-bottomed 
soil, rather moist on the surface. Young plants are 
obtained from seed, which should be sown in April, 
on finely -prepared soil. After the seeds are sown, 
a light roller should bje drawn over the bed, to 
press the seeds firmly into the earth, and they 
should then have a thin covering of soil. The 
plants are generally allowed to remain two years 
in the seed-bed, and afterwards planted into nursery 
lines, or where they are finally to remain. As the 
Larch vegetates earlier than most other trees, and 
suflFers more if removed after it has begun to grow’, 
it ought to be transplanted in autumn, or early in 
spring. We have adopted the names of the species 
and varieties as given by Mr. Loudon in his very 
valuable work, the Arboretum et Fruticetum Briian- 
nicum. Synonymea: 1. Pinua laricina, P. micro- 
carpa, Abiea microcarpa. 2. L. pendula, Pinua pen-

loam, peat, and sand, is best adapted to the growth 
of these pretty shrubs; and young cuttings will 
root frsely in sand, under a glass.
