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 (according to [a
href="http:]/www.jaxmed.com/articles/Diseases/poison_ivy_dermatitis.htm">Charles
H. Booras). See Poison sumac. It is related to {poison
oak}, and is also called mercury.

radicans}) in common terminology, but more properly

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. (Zool.) Same as Poison gland, above. See
Illust. under Fang.
Poison sumac (Bot.), a poisonous shrub formerly considered
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]

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 (according to [a
href="http:]/www.jaxmed.com/articles/Diseases/poison_ivy_dermatitis.htm">Charles
H. Booras). See Poison sumac. It is related to {poison
oak}, and is also called mercury.

in California and Oregon. Opinion varies as to whether the
poison oak and poison ivy are only variants of a single

Poison sumac (Bot.), a poisonous shrub formerly considered

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.

Usage: Poison, Venom. Poison usually denotes something

Mercury has a molecule which consists of only one atom. It
was named by the alchemists after the god Mercury, and
designated by his symbol, [mercury].

Note: Mercury forms alloys, called amalgams, with many
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
compounds as calomel, corrosive sublimate, etc. It is

Poison sumac (Bot.), a poisonous shrub formerly considered
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.

Usage: Poison, Venom. Poison usually denotes something
received into the system by the mouth, breath, etc.

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 (according to [a
href="http:]/www.jaxmed.com/articles/Diseases/poison_ivy_dermatitis.htm">Charles
H. Booras). See Poison sumac. It is related to {poison
oak}, and is also called mercury.

lumped together with the poison ivy ({Toxicodendron
radicans}) in common terminology, but more properly

in California and Oregon. Opinion varies as to whether the
poison oak and poison ivy are only variants of a single
