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.[5][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.[6] Fruits are red and the plant grows grows from a coated bulb 2-3 in (5.1-7.6 cm) below the soil surface.[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.[7]
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.[7]
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.[8][6] In Virginia, at least 16 species serve as pollinators to A. muscitoxicum, including Trichiotinus affinus (hairy flower scarab), Anoplodera octonotata, A. vittata, A. circumdata, Grammoptera haematites, Leptura lineola, Encyclops coerulea, Callimoxys sanguinicollis, Odontota dorsalis, Epargyreus clarus (silver-spotted skipper), Celastrina argiolus (holly blue), Papilio glaucus (eastern tiger swallowtail), Colias philodice (common sulphur or clouded sulphur), Apis mellifera (European honey bee), and Xylocopus americanus (carpenter bee).[8]
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.[9] It is also poisonous to other animals, being capable of killing a sheep within 24 hours of consumption and even sicken or kill larger cattle including mules and horses. Such poisonings usually occur in the spring when the 4-6 in (10.2-15.2 cm) green grass-like leaves start to grow.[3]
Conservation and Management
Cultivation and restoration
Propagation can be performed by planting seeds when ripe in the spring or through rood divisions.[4]
