413. THRINAX ARGENTEA.--This beautiful palm is called the Silver Thatch

palm of Jamaica, and is said to yield the leaves so extensively

used in the manufacture of hats, baskets, and other articles. It

is also a native of Panama, where it is called the broom palm, its

leaves being there made into brooms.

414. TILLANDSIA ZEBRINA.--A South American plant of the pineapple

family; the bottle-like cavity at the base of the leaves will

sometimes contain a pint or more of water, and has frequently

furnished a grateful drink to thirsty travelers.

415. TINOSPORA CORDIFOLIA.--A climbing plant, so tenacious of life that

when the stem is cut across or broken, a rootlet is speedily sent

down from above, which continues to grow until it reaches the

ground. A bitter principle, _calumbine_, pervades the plant. An

extract called galuncha is prepared from it, considered to be a

specific for the bites of poisonous insects and for ulcers. The

young shoots are used as emetics.

416. TRIPHASIA TRIFOLIATA.--A Chinese shrub, with fruit about the size

of hazelnuts, red-skinned, and of an agreeable sweet taste; when

green, they have a strong flavor of turpentine, and the pulp is

very sticky. They are also preserved whole in sirup, and are

sometimes called limeberries.

417. TRISTANIA NERIIFOLIA.--A myrtaceous plant from Australia, called

the turpentine tree, owing to its furnishing a fluid resembling

that product.

418. URCEOLA ELASTICA.--A plant belonging to the _Apocynaceæ_, a native

of the islands of Borneo and Sumatra, where its milky juice,

collected by making incisions in its soft, thick, rugged bark, or

by cutting the trunk into junks, forms one of the kinds of

caoutchouc called juitawan, but it is inferior to the South

American, chiefly owing to want of care in its preparation, the

milky juice being simply coagulated by mixing with salt water,

instead of being gradually inspissated in layers on a mold. The

fruit contains a pulp which is much eaten by the natives.

419. URENA LOBATA.--A malvaceous plant, possessing mucilaginous

properties, for which it is used medicinally. The bark affords an

abundance of fiber, resembling jute rather than flax or hemp.

420. UVARIA ODORATISSIMA.--An Indian plant which is supposed to yield

the essential oil called Ylang-Ylang, or Alan-gilan. This oil is

obtained by distillation from the flowers, and is highly esteemed

by perfumers, having an exquisite odor partaking of the jasmine

and lilac.

421. VANGUERIA EDULIS.--A cinchonaceous plant, the fruits of which are

eaten in Madagascar under the name of Voa-vanga. The leaves are

used in medicine.

422. VANILLA PLANIFOLIA.--The vanilla plant, which belongs to the

orchid family. The fruit is used by confectioners and others for

flavoring creams, liquors, and chocolates. There are several

species, but this gives the finest fruit. It is a climbing orchid,

and is allowed to climb on trees when cultivated for its fruit. In

Mexico, from whence is procured a large portion of the fruit, it

is cultivated in certain favorable localities near the Gulf coast,

where the climate is warm. Much of the value of the bean depends

upon the process of its preparation for the market. In Mexico,

where much care is given to this process, the pods are gathered

before they are fully ripe and placed in a heap, under protection

from the weather, until they begin to shrivel, when they are

submitted to a sweating process by wrapping them in blankets

inclosed in tight boxes; afterwards they are exposed to the sun.

They are then tied into bundles or small bales, which are first

wrapped in woolen blankets, then in a coating of banana leaves

first sprinkled with water, then placed in an oven heated up to

about 140° F. Here they remain for twenty-four to forty-eight

hours, according to the size of the pods, the largest requiring

the longest time. After this heating they are exposed to the sun

daily for fifty or sixty days, until they are thoroughly dried and

ready for the market.

423. VATERIA INDICA.--This plant yields a useful gum resin, called

Indian copal, piney varnish, white dammar, or gum anine. The resin

is procured by cutting a notch in the tree, so that the juice may

flow out and become hardened. It is used as a varnish for

pictures, carriages, etc. On the Malabar coast it is manufactured

into candles, which burn with a clear light and an agreeable

fragrance. The Portuguese employ this resin instead of incense.

Ornaments are fashioned from it under the name of amber. It is

also employed in medicine.

424. WEINMANNIA RACEMOSA.--A New Zealand tree called Towhia by the

natives of that country. Its bark is used for tanning purposes,

and as a red and brown dye, which give fast colors upon cotton

fabrics.

425. WRIGHTIA TINCTORIA.--The leaves of this plant furnish an inferior

kind of indigo. The wood is beautifully white, close-grained, and

ivory-like, and is much used for making Indian toys.

426. XANTHORRH[OE]A ARBOREA.--The grass gum tree of Australia, also

called black boy. This is a liliaceous plant, which produces a

long flower-stalk, bearing at the top an immense cylindrical

flower-spike, and when the short black stem is denuded of leaves,

the plants look very like black men holding spears. The leaves

afford good fodder for cattle, and the tender white center is used

as a vegetable. A fragrant resin, called acaroid resin, is

obtained from it.

427. XIMENIA AMERICANA.--A small tree, found in many warm regions;

among others in southern Florida. In Brazil it is called the

Native Plum on account of its small yellow fruits, which have a

subacid and somewhat astringent aromatic taste. The wood is

odoriferous and is used in the West Indies as a substitute for

sandalwood.

428. YUCCA AL[OE]FOLIA.--The yucca leaves afford a good fiber, and some

southern species are known as _bear's grass_. The root stems also

furnish a starchy matter, which has been rendered useful in the

manufacture of starch.

429. ZAMIA FURFURACEA.--This plant belongs to the order _Cycadaceæ_,

and is grown to some extent for the starchy matter contained in

the stem, which is collected and used as arrowroot; but it is not

the true arrowroot, that being produced by a species of _Maranta_.

430. ZAMIA INTEGRIFOLIA.--The coontie plant of Florida. The large

succulent roots afford a quantity of arrowroot, said to be equal

to the best of that from Bermuda. The fruit has a coating of an

orange-colored pulp, which is said to form a rich edible food. It

was from the roots of this plant that the Seminoles of Florida

obtained their _white meal_.

431. ZINGIBER OFFICINALE.--This plant is cultivated in most warm

countries for the sake of its rhizomes, which furnish the spice

called ginger. It is prepared by digging up the roots when a year

old, scraping them, and drying them in the sun. Ginger, when

broken across, shows a number of little fibers embedded in floury

tissue. Its hot pungent taste is due to a volatile oil. It also

contains starch and yellow coloring matter. Ginger is used for

various medicinal purposes, and in many ways as a condiment, and

in the preparation of cordials and so-called teas.
