Taxonomic Notes

Synonym: Allium bivalve;[1][2] Ornithogalum bivalve[2]

Description

Nothoscordum bivalve is a bulbous[3] monoecious perennial forb/herb.[2] It is an onion-like plant but typically lacks an odor.[1]

Distribution

This species is found from southeastern Virginia, westward to southern Ohio and Kansas, southward to central peninsular Florida, Texas, and South America.[1]

Ecology

Habitat

N. bivalve occurs around granite flatrocks, in various glades and barrens, open woodlands, along roadsides, fields,[1][3] disturbed soils, low sandy woods, meadows, prairies, parking strips of towns, and rocky glades of limestone, chert, granite or sandstone. In Tennessee cedar (limestone) glades, N. bivalve is most abundant where soil is 10-15 cm deep. It can be found in glades that are flooded during winter and early spring and in those that are unflooded. During summer months in this habitat, soils moisture is frequently below the wilting coefficient.[3]

Associated species in Tennessee glades include Erigeron strigosus, Hypericum sphaerocarpum, Isanthus brachiatus, Isoetes butleri, Ophioglossum engelmanni, Petalostemon gattingeri, Psoralea subacaulis, Ruellia humilis, Satureja glabella, Scutellaria parvula, Senecio smallii, and Sporobolus vaginiflorus.[3]

Phenology

In the southeastern and mid-Atlantic United States, N. bivalve flowers from mid-March through mid-May and in September through December. Fruiting occurs in May through June and from October through January.[1] For the Florida panhandle, reports of flowering primarily occur from January through May, peaking between February and April. Records of flowering also occurred in September through November, but in reduced numbers compared to the spring.[4]

Use by animals

Herbivory by grazers is low for this species,[5] but trace amounts have been found in white tailed deer rumen of southern Texas.[6] Relative abundance peaks in properly grazed prairies and overgrazed but uneroded prairies.[5]
