SILENE NIVEA (Nutt.)
HABIT: Erect or leaning, herbaceous, rhizomatous perennial,
2-7 dm.; flowering June, July; fruiting July, August.
SIMILAR SPECIES: This species has distinctive characters that
set it apart from the similar Silene noctiflora and Lychnis alba. S.
nivea has mostly glabrous to puberulent stems, long, narrowly-lanceolate
leaves, a few-flowered, leafy inflorescence with the leaves appearing axillary,
a tubular-campanulate calyx, and slightly notched petals. L. alba has coarsely pubescent stems,
glandular above, lanceolate to broadly elliptic leaves, a much-branched
inflorescence with foliar primary bracts, a tubular calyx, and deeply-bilobed
noctiflora has coarsely hirsute
stems, ovate-lanceolate to elliptic-lanceolate leaves, a loosely-branched
inflorescence, an ovoid-campanulate calyx, and deeply-bilobed petals.
TOTAL RANGE: PA, MD, and VA, w. to TN, MN, SD, NE, and MO.
STATE RANGE: There are post-1960 specimens from Butler
County, and a dubious collection from Wood County. There are pre-1960 records
from 3 other counties of southwest Ohio: Clermont, Greene, and Hamilton.
STATE STATUS: 1980-1981: Presumed Extirpated, 1982 to
HABITAT: Rich woods and alluvium, disturbed floodplains and
HAZARDS: Drying of habitat; soil compaction; casual picking
of conspicuous flowers.
RECOVERY POTENTIAL: Unknown, but possibly good, as evidenced
by its occurrence in disturbed situations.
INVENTORY GUIDELINES: Collect mature flowering or fruiting
material with a small portion of the rhizome; avoid over-collecting.
COMMENTS: This species should be sought throughout southwest
Ohio. It may be overlooked because it resembles other white-flowered campions
(see Similar Species).
