THRIET,—botanically Armeria. A genus of 
ornamental, small, evergreen plants, of the plum- 
bago family. It was formerly included in the 
genus statice; and, as now constituted, it com- 
prises two indigenous species, and about 18 exotic 
ones,—all of which have been introduced to Bri- 
tain, and deserve a place in the flower-garden. 
One species is a greenhouse shrub of about 2 feet 
in height ; and all the others are hardy perennial 
herbs, varying in height from 4 to 25 inches. 
Most of the species have pink flowers; and the 
others have either scarlet, crimson, purple, flesh- 
coloured, or white flowers. Nearly all thrive 
best in a soil of sandy loam; and all are propa- 
gable by radical division. 
The sea-side thrift, or sea-pink, Armeria mari- 
tuma, called by the older botanists Statice armeria, 
abounds on the marshy sea-shores of many parts 
of Britain. It occurs chiefly in places which are 
regularly overflown at high water; and it some- 
times adorns great tracts of sea-marsh, and ren- 
ders them deeply verdant at all seasons, and 
brilliantly beautiful during the season of bloom ; 
and it is raised and cultivated in many a flower- 
garden as an edging for borders. Its leaves are 
very narrow, short, and plain; its stems seldom 
rise more than 4 inches high; and its flowers 
grow in small dense heads at the top of the stems, 
and have a red or flesh colour, and bloom from 
May till July—The mountain thrift, Armeria 
montana, grows wild on some of the lofty moun- 
tains of the Scottish Highlands, and is about the 
same height as the preceding, and has pink-col- 
oured flowers, and blooms in May and June. 
The common thrift, Armeria vulgaris, is a na- 
tive of the Alps and of other cold mountains of 
Continental Europe, and was long ago introduced 
to Britain, and has long been more or less es- 
teeined as an edging-plant for flower-borders, 
and is often mistaken for the sea-side thrift. 
Its roots are fibrous, and divide into heads; its 
leaves are numerous, narrow, and grass-like, and 
have three corners at their base, and sit close to 
the root-heads; the stems rise from the embrace 
of the mutually overlying parts at the bases of 
the leaves, and are naked and about 6 inches 
high ; and its flowers grow in heads, on one com- 
mon scaly calyx, at the top of the stems, and 
till August. A variety of this species has bright 
red flowers, and makes a much better appear- 
ance, and is more esteemed for edgings, than the 
normal plant.—The broad-leaved thrift, Arme- 
ria latifolia, has much larger leaves, and much 
loftier stems, than the common thrift, and car- 
ries light red flowers from May till July; and it 
was introduced to Britain upwards of a century 
ago, and makes considerable claims on the culti- 
vator’s attention; but it differs from almost all 
the other thrifts in loving a soil of a somewhat 
peaty kind. 
THRINCIA. A genus of yellow-flowered her- 
baceous plants, of the succory division of the 
composite order. The simple-haired species, 7’. 
hirta, grows wild in the grass lands of some parts 
of Britain; and is perennial-rooted, and has a 
height of about 20 inches, and blooms in July 
and August. Two annual species, and a tuber- 
ous-rooted one, all hardy and about a foot high, 
have been introduced from other countries; but 
neither these species, nor the indigenous one, 
possess much interest. 
THROATING. The mowing of beans against 
their bending. This is done only with a thin 
crop. 
THROATWORT,—botanically Zracheliwm. A 
genus of exotic, ornamental, herbaceous plants, 
of the bellflower family. The blue ‘species, 
Trachelium ceruleum, grows naturally in shady 
woods in many parts of Italy, and was introduced 
to Britain in 1640. Jt is a hardy biennial or 
short-lived perennial. Its root is fleshy and 
tuberous, and sends out many wide-spreading 
fibres; its radical leaves are ovate-lanceolate, 
serrate, pointed, and about two inches long and 
one inch broad; its stems are irregularly gar- 
nished with similar leaves to the radical ones, 
and have a height of from 18 to 25 inches; and 
its flowers grow in compound, many-flowered 
umbels, and have a small funnel-shaped corolla 
of an azure colour, and bloom from July till 
September. This plant is propagated from au- 
tumn-sown seeds, and loves a soil of rich mould, 
and also thrives well and maintains itself for an 
indefinite period and makes a fine appearance 
upon old walls which contain a sufficient quan- 
tity of soil for the lodging of its seeds and the 
anchoring of its roots—The name throatwort is 
likewise borne by a beautiful indigenous plant 
of the bellflower genus. See the article Brni- 
FLOWER. 
THRUSH,—scientifically Zurdus. A large and 
interesting group of passerinous song-birds. They 
have a compresed and arcuated bill, not hooked 
in the point, and graduating off, in some of the 
species, into a resemblance to that of the shrikes; 
and they have solitary habits, and feed for the 
most part on berries or similar fruits. One great 
subdivision of them, comprising the blackbird 
and the brown thrushes, have the colours of the 
plumage uniform or distributed in large masses ; 
have a pale purple colour, and bloom from June |and another large subdivision, comprising the 
THRUSH. | |
