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).[4] However, earlier sources report it reaching heights of 1.5-4 ft (0.46-1.22 m).[3] 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.[4] 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.[5] Fruits are red.[3]
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] It is reported to grow in Virginia at an elevation of 4,000 ft (1,219 m) and inhabits sandy soils throughout its range.[3] In a North Carolina longleaf pine study, A. muscitoxicum vegetation was present only in disturbed sites.[6]
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.[6]
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.[5]
Use by animals
Humans use it to kill flies by taking the pulp from crushed bulbs and mixing it with sugar.[4] Native Americans would also use A. muscitoxicum to kill crows and as a severe cure for the itch.[7]
Conservation and Management
Cultivation and restoration
Propagation can be performed by planting seeds when ripe in the spring or through rood divisions.[4]
