Oak \Oak\ ([=o]k), n. [OE. oke, ok, ak, AS. [=a]c; akin to D.
eik, G. eiche, OHG. eih, Icel. eik, Sw. ek, Dan. eeg.]
[1913 Webster]
1. (Bot.) Any tree or shrub of the genus Quercus. The oaks
have alternate leaves, often variously lobed, and
staminate flowers in catkins. The fruit is a smooth nut,
called an acorn, which is more or less inclosed in a
scaly involucre called the cup or cupule. There are now
recognized about three hundred species, of which nearly
fifty occur in the United States, the rest in Europe,
Asia, and the other parts of North America, a very few
barely reaching the northern parts of South America and
Africa. Many of the oaks form forest trees of grand
proportions and live many centuries. The wood is usually
hard and tough, and provided with conspicuous medullary
rays, forming the silver grain.

Poison ivy (Bot.), a poisonous climbing plant (formerly
Rhus Toxicodendron, or Rhus radicans, now classified
as Toxicodendron radicans) of North America. It is
common as a climbing vine, especially found on tree
trunks, or walls, or as a low, spreading vine or as a
shrub. As a low vine it grows well in lightly shaded
areas, recognizable by growing in clusters of three
leaves. Its leaves are trifoliate, rhombic-ovate, and
variously notched. Its form varies slightly from location
to location, leading to some speculation that it may
consist of more than one species. Many people are poisoned
by it, though some appear resistant to its effects.
Touching the leaves may leave a residue of an oil on the
skin, and if not washed off quickly, sensitive areas of
skin become reddened and develop multiple small blisters,
lasting for several days to several weeks, and causing a
persistent itch. The toxic reaction is due to an oil,
present in all parts of the plant except the pollen,
called urushiol, the active component of which is the
compound pentadecylacatechol. See Poison sumac. It is
related to poison oak, and is also called mercury.
Poison nut. (Bot.)
(a) Nux vomica.
(b) The tree which yields this seed ({Strychnos
Nuxvomica). It is found on the Malabar and Coromandel
coasts.
Poison oak (Bot.), a dermatitis-producing plant often
lumped together with the poison ivy ({Toxicodendron
radicans) in common terminology, but more properly
distinguished as the more shrubby Toxicodendron
quercifolium (syn. Toxicodendron diversilobum), common
in California and Oregon. Opinion varies as to whether the
poison oak and poison ivy are only variants of a single
species. See poison ivy, above.
Poison sac. (Zo["o]l.) Same as Poison gland, above. See
Illust. under Fang.
Poison sumac (Bot.), a poisonous shrub formerly considered
Rhus+({Rhus+venenata" rel="nofollow">to be of the genus Rhus ({Rhus venenata), but now
classified as Toxicodendron vernix; -- also called
poison ash, poison dogwood, and poison elder. It has
pinnate leaves on graceful and slender common petioles,
and usually grows in swampy places. Both this plant and
the poison ivy ({Toxicodendron radicans, formerly Rhus
Toxicodendron) have clusters of smooth greenish white
berries, while the red-fruited species of this genus are
harmless. The tree ({Rhus vernicifera) which yields the
celebrated Japan lacquer is almost identical with the
poison sumac, and is also very poisonous. The juice of the
poison sumac also forms a lacquer similar to that of
Japan.
[1913 Webster +PJC]
Syn: Venom; virus; bane; pest; malignity.
Usage: Poison, Venom. Poison usually denotes something
received into the system by the mouth, breath, etc.
Venom is something discharged from animals and
received by means of a wound, as by the bite or sting
of serpents, scorpions, etc. Hence, venom specifically
implies some malignity of nature or purpose.

was named by the alchemists after the god Mercury, and
designated by his symbol, [mercury].

metals, and is thus used in applying tin foil to the
backs of mirrors, and in extracting gold and silver
from their ores. It is poisonous, and is used in
medicine in the free state as in blue pill, and in its
