Common Name: fly-poison[1][2]

Taxonomic Notes

Synonyms: A. muscaetoxicum;[1] Chrosperma muscaetoxicum; Zigadenus muscitoxicus;[1][2]

Description

Amianthium muscitoxicum is a monoecious perennial forb/herb.[2] It has narrow elongated leaves and reaches lengths of 12-24 in (30-61 cm). Flowers are initially white, but turn a bronzy-green, and occur in dense showy racemes. All parts of the plant are poisonous, containing a very toxic alkaloid.[3] In a study, the average fruit set, seeds per fruit, and total seeds per plant ranged from 0.59-0.67, 1.72-2.27, and 16.7-20.7, respectively, depending upon the pollination distance.[4]

Distribution

This species occurs from southern New York, Pennsylvania, Missouri, and Oklahoma, southward to the Florida panhandle, Mississippi, and Arizona.[1]

Ecology

Habitat

A. muscitoxicum occurs from 5-1,600 m in elevation across a wide variety of mesic to dry forests, pine savannas, sandhills, and meadows.[1]

Phenology

In the Southeastern and mid-Atlantic United States, flowering occurs from May through July and fruiting from July through September.[1]

Seed bank and germination

Despite being present in a North Carolina disturbed longleaf pine habitat, no evidence of its presence in the seed bank was found.[5]

Pollination

The distance of pollinating neighbors has some influence on the production and weight of seeds. However, heterogeneity between plants accounted for a greater amount of variance between seed production and weight.[4]

Use by animals

Humans use it to kill flies by taking the pulp from crushed bulbs and mixing it with sugar.[3] Native Americans would also use A. muscitoxicum to kill crows and as a severe cure for the itch.[6]

Conservation and Management

Cultivation and restoration

Propagation can be performed by planting seeds when ripe in the spring or through rood divisions.[3]
