Common
Name: Fly Poison, Stagger
grass, Crow poison - The high
toxicity of the plant to fauna is reflected in its baneful name.
Scientific
Name: Amianthium muscaetoxicum – The
Greek word for pure is amiantos which,
when coupled with the word for flower, anthos
produces the generic name ‘pure flower.’ This is alleged to indicate that the
flower, unlike most other lilies, lacks nectar producing glands (nectaries) at
the base of the tepals. The specific
name is literally Latin for fly poison (musca toxicum). It
is alternatively listed as Chrosperma
muscaetoxicum in some older texts and it is also frequently found in the
genus Zigadenus. The generic
confusion is somewhat perplexing, as the plant is a monotype – it is the only
species in the genus.
The various common names of this ubiquitous and prolific spring
flower attest to its substantive toxic properties that were well known to the
Native American population that preceded European colonization. The Cherokee used
the plant both as a medicinal and as a toxin; the root was ground to make a
poultice for application to treat severe itching and alternatively mixed into
an otherwise attractive morsel as a means to poison crows. It is implicit in
this application that the Cherokee sought to exterminate the persistent corvine
marauders that would otherwise vandalize their cornfields - the same rationale
that motivated the later use of the scarecrow. The Indian herbalism was adopted
by the European colonists who parlayed the toxic plant into a potent means to
eradicate the ubiquitous flies, resulting in the widely used name ‘fly poison’
as a mnemonic descriptor. The sobriquet ‘stagger grass’ was also coined by the
colonists to describe the effects that ingestion of A. muscaetoxicum had on the herd animals that they introduced to
the cleared woodlands of the early settlements.
Grazing animals will generally shun poisonous plants as the
inherent bitterness of the alkaloid toxins will minimize their exposure in
favor of greener pastures. However, when there is a dearth of alternative
fodder vegetation for the grazer, the likelihood of toxic plant consumption
increases. This is exacerbated by the benign appearance of the immature plant,
a veritable tuft of proffered nutrition.
A 1913 citation in the U. S.
Department of Agriculture Farmer’s Bulletin enjoined farmers to “recognize
this fact and take a few obvious precautions,” such as: don’t let your animals
graze on the range when there is nothing to graze on; and to keep animals away
from poisonous plants. Special precautions are enjoined when animals are in
transit from one location to another over commonly used trails, as most of the
good fodder would have been consumed, leaving only the poisonous
leftovers. In addition to stagger grass,
the Bulletin also warns against milkweed, larkspur, wild cherry, and water
hemlock or cicuta.
