T H Ú J A , Linn. From thyon, a sacrifice ; the
resin of the Eastern variety is used instead of
incense at sacrifices. Why it is called Arbor
Vitoe is not known, unless it be on account of
the supposed medicinal qualities of its berries.
In the East, the cypress is called the tree of
life ; and its berries are considered a cure for
THU 557 THY
all diseases. Linn. 21, Or. 10, Nat. Or. Pináceas.
In Britain the species of Arbor Vitm
can only be considered as ornamental, low
shrubs or trees, well deserving of being cultivated,
especially T. péndula; which, on account
of its veiy graceful, long, slender, pendulous
shoots, ought to be in every collection.
The American and European kinds succeed
well in any soil or situation, but prefer low,
sheltered, and swampy places. ^ The more
tender species, natives of China, require,
when young, the j)rotection of the greenhouse.
They arc ail readily increased by seeds, either
imported from the places of their natural
growth, or gathered from the trees in this
country ; some of the rarer kinds, as T. yèndula,
are propagated by cuttings. Synonymes :

of a sweet-scented herb. Linn. 14, Or. 1,

plants. A gravelly soil suits it best, and it is
readily increased by young cuttings or seeds.

TiiYMELElcEiE, or DAPHNADS. The Mezereon
{Daphne Mezereum) and Spurge laurel {Ddphne

THVMUS, Linn. From thiimos, courage, strength,
the smell of thyme being reviving ; or from
thuo, to perfume, being formerly used for incense
in the temples. Ldnn. 14, Or. 1, Nat.
Or. Lamiacece. Well-known under shrubs or
herbs, preferring an ex])osed situation, and a
dry, light, sandy soil. They are of very easy
culture, and may be increased with facility
either by divisions, slips, cuttings, or by seeds
sown in March or April. Some of the rarer
species may be grown in pots among alpine
plants, and protected in winter. The diiforent
pur
wel
poses to which Thyme is applied are so
known, as not to require any notice here.
