Amyl alcohol \Am"yl al"co*hol\ (Org. Chem.)
Any of eight isomeric liquid alcohols (C5H11.OH),
transparent, colorless liquids. It is the hydroxide of amyl.
Also called amylic alcohol. The amyl alcohol obtained from
fusel oil is mostly isoamyl alcohol (3-methyl-1-butanol or
1-hydroxy-3-methylbutane), with some sec-amyl alcohol
(2-methyl-1-butanol or 2-pentanol), and has a
characteristic peculiar odor. Other than n-amyl alcohol
(also called 1-pentanol) the other isomeric pentanols are
not usually refered to as amyl alcohol. The amyl alcohol
mixture in fusel oil forms a colorless liquid with a peculiar
cough-exciting odor and burning taste. It is used as a source
of amyl compounds, such as amyl acetate, amyl nitrite, 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.

radicans}) in common terminology, but more properly

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. (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]

[1913 Webster]

Vegetable kingdom (Nat. Hist.), that primary division of
living things which includes all plants. The classes of
the vegetable kingdom have been grouped differently by
various botanists. The following is one of the best of the
many arrangements of the principal subdivisions.
[1913 Webster] I. Phaenogamia (called also
Phanerogamia). Plants having distinct flowers and true
seeds. [ 1. Dicotyledons (called also Exogens). --
Seeds with two or more cotyledons. Stems with the pith,
woody fiber, and bark concentrically arranged. Divided
into two subclasses: Angiosperms, having the woody fiber
interspersed with dotted or annular ducts, and the seeds
contained in a true ovary; Gymnosperms, having few or no
ducts in the woody fiber, and the seeds naked. 2.
Monocotyledons (called also Endogens). -- Seeds with
single cotyledon. Stems with slender bundles of woody
fiber not concentrically arranged, and with no true bark.]
[1913 Webster] II. Cryptogamia. Plants without true
flowers, and reproduced by minute spores of various kinds,
or by simple cell division. [ 1. Acrogens. -- Plants
usually with distinct stems and leaves, existing in two
alternate conditions, one of which is nonsexual and
sporophoric, the other sexual and oophoric. Divided into
Vascular Acrogens, or Pteridophyta, having the
sporophoric plant conspicuous and consisting partly of
vascular tissue, as in Ferns, Lycopods, and Equiseta, and
Cellular Acrogens, or Bryophyta, having the sexual
plant most conspicuous, but destitute of vascular tissue,
as in Mosses and Scale Mosses. 2. Thallogens. -- Plants
without distinct stem and leaves, consisting of a simple
or branched mass of cellular tissue, or reduced to a
single cell. Reproduction effected variously. Divided into
Algae, which contain chlorophyll or its equivalent, and
which live upon air and water, and Fungi, which contain
no chlorophyll, and live on organic matter. (Lichens are
now believed to be fungi parasitic on included algae.]
[1913 Webster]

Note: Many botanists divide the Phaenogamia primarily into
Gymnosperms and Angiosperms, and the latter into
Dicotyledons and Monocotyledons. Others consider
Pteridophyta and Bryophyta to be separate classes.
Thallogens are variously divided by different writers,
and the places for diatoms, slime molds, and stoneworts
are altogether uncertain.
