Thka, Linn- Derived from Teha, the Chinese name 
for tea. Linn. 16, Or. 8, Nat. Or. Ternstrbmiaceae. 
For the culture and propagation of these valuable 
plants, see Camellia. They only require to be pro- 
tected from severe frost. All the different kinds 
of tea imported into this country from China, are 
the produce of T. viridis, the differences depending 
entirely upon soil and climate, and the different 
ages at which their leaves are gathered, and the 
modes of drying. Tea is said to be the best of all 
medicines, moderately and properly taken; it is 
gently astringent ; it strengthens the stomach and 
bowels ; and is efficacious against indigestions. It 
refreshes the spirits in heaviness and sleepiness, 
and appears to counteract the effects of inebriating 
liquors. The immoderate use of it is very preju- 
diciad. From Dr. Smith’s experiments, it appears 
that green tea has the power of destroying the sen- 
sibility of the nerves and the irritability of the 
muscles. For a very valuable account of this plant 
see Royle’ s Illustrations of the Himalayan Mountains, 
p. 107. Synonymes: 1. T. chinensis Bohea. 2. T.

Theobboma, Linn. From theos, god, and broma, food ;

The species of Theobroma or Choc^olate-nut grow 
well in a mixture of loam and peat ; and cuttings 
root readily in sand, under a glass, in heat. Seeds 
do not retain their vegetative power for a great 
length of time. The seeds of T. Cacao furnish the 
chocolate of the shops. The seeds are very nourish- 
ing and agreeable to most people, and are, therefore, 
kept in the majority of the houses in America as a 
necessary part of the provisions of the family,

Theophb.asta, Linn. Named after Theophrastus, the 
father of natural history. Linn. 5, Or. 1, Nat. Or. 
Myrsinacece. A small, handsome tree, with a tuft 
of long, evergreen branches at the top of its simple 
stem, something like a palm-tree. It is well worth 
cultivating, on account of its long, holly-like leaves. 
A mixture of peat, loam, and sand, suits it best ; 
and cuttings, with the leaves entire, root readily 
in sand, under a glass, in heat. Bread is said to 
be prepared from the pounded seeds of this tree in 
St. Domingo, w'here it is called Le Petit Coco.

Thermopsis, R. Brorvn. From thermos, a lupine, and 
opsis, resemblance ; because of the resemblance of 
the species to lupines. Linn. 10, Or. 1, Nat. Or. 
Leguminosce. The species of Thermopsis are very 
elegant, but rather difficult to preserve. They 
succeed best in a light, rich soil ; and the safest 
way of increasing them is by seed ; for when the 
plants are separated at the roots they are very liable 
to suffer. Synonymes : 1. Podalyria alpina, Sophora
