Slide2Birthwort Family
The
Aristolochiaceae
, or the Birthwort family, are a family
of flowering plants with 8 genera and about 400 species
belonging
to the order Piperales.
The
type genus is
Aristolochia
L
. The
Aristolochiaceae are
magnoliids, a basal group of
angiosperms which are not part of the large categories of
monocots or
eudicots
. Some
newer classification schemes, such as the Update of the
Angiosperm Phylogeny Group, place the family Aristolochiaceae in the order
Piperales, but it is still quite
common,
for the Aristolochiaceae to be assigned, sometimes with some other families, their own order (
Aristolochiales)
.
Slide3Birthwort Family
They are mostly
perennial,
herbaceous plants,
shrubs, woody
vines or even
lianas. The membranous, cordate simple
leaves are spread out, growing alternately along the stem on leaf stalks. There are no
stipules. The bizarre
flowers are large to medium-sized, growing in the leaf axils. They are bilaterally or radially symmetrical.
Many members of Aristolochia and some of Asarum contain the toxin
aristolochic acid, which discourages
herbivores and is known to be
carcinogenic in
rats. Aristolochia itself is carcinogenic to
humans.

Slide6Wild Ginger
Asarum
consists low-growing herbs , that are distributed over the north temperate zones with most species in Asia (mainly China, Japan and Vietnam), North America and one species in Europe
.
Biogeographically,
Asarum
originated in
Asia. They
have characteristically kidney-shaped leaves, growing from
creeping rhizomes. They bear small,
axillary
brown
or
reddish
flowers.
Slide7Wild Ginger
Asarum canadense is native to the forests of eastern
North America. It is found from the
Great Plains east to the
Atlantic Coast, and from southeastern
Canada south to approximately the
fall line in the southeastern
United States.
The plant is called wild ginger because the
rhizome tastes and smells similar to that of
ginger root, but the two are not particularly related. The root can be used as a
spice, but is a potent
diuretic, or urinary stimulant.
