Thuja, Linn. From ihyon, a sacrifice ; the resin of 
the Eastern variety is used instead of incense at 
sacrifices. Why it is called Arbor Vita 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 all di.seases. lAnn. 21 , Or. 10, 
Nat. Or. Conifera. In Britain the species of Arbor 
Vita can only be considered as ornamental, low 
shrubs or trees, well deserving of being cultivated, 
especially T.pendula; which, on account of its very 
graceful, long, slender, pendulous shoots, ought to 
be in every collection. The American and European 
J:inc!s 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 protection of the greenhouse. They 
are all 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. pendula, are propagated by cuttings.

ThThbra, Linn. Thymbra is the Greek name of a 
sweet-scented herb. Linn. 14, Or. 1, Nat. Or. 
Labiata. This plant is well adapted for rock-work, 
or growing in pots among alpine plants. A gra- 
velly soil suits it best, and it is readily increased by 
young cuttings or seeds. Synonyms ; 1. T. verti- 
cillata.

Themi s, Linn. Fr om thnnx QS, courag e, strength, the 
smell of thyme*^eing reviving ; or from thuo, to 
perfume, being formerly used for incense in the 
temples. Linn. 14, Or. 1, Nat. Or. Labiuta. Well 
known under shrubs or herbs, preferring an exposed 
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 raier 
species may be grown in pots among alpine plants, 
and protected in winter. The different purposes 
to which Thyme is applied are so well known, as 
not to requite any notice here. Synonymes: 1. T.
