SYNONYMS: Stenanthium robustum S. Wats. (= var. robustum
(S. Wats.) Fern.
HABIT: Stems arising from bulbous base are leafy below, reduced
upwards to panicle, 0.25-1.9 m; flowers and fruits June-Sept.
SIMILAR SPECIES: This genus, with only one species in Ohio,
is very distinctive with its long grass-like leaves, panicled inflorescence and
many smallish white flowers. Two types of flowers are present. Flowers of
panicle branches are staminate, whereas flowers of the terminal unbranched axis
TOTAL RANGE: PA, OH, IN and MO, s. to FL and AR.
STATE RANGE: There are post-1960 records from Gallia,
Jackson, Lawrence, Pike and Scioto Counties. There are pre-1960 records from
Adams, Hamilton, Licking and Stark Counties.
STATE STATUS: 1980-1987: Potentially Threatened,
1988 to present: Threatened.
HABITAT: Moist rocky woods, rich wooded slopes; most
frequent on acid soils.
HAZARDS: Possibly overgrowth by woody species as a result of
succession; destruction of habitat by mining or logging.
RECOVERY POTENTIAL: Possibly poor; the species appears to be
difficult to transplant (Deam 1940).
INVENTORY GUIDELINES: Collect mature flowering specimens.
COMMENTS: Two intergrading varieties occur in Ohio. The var.
robustum is larger with wider leaves and a denser, longer panicle. The
var. robustum has erect fruits, whereas var. gramineum has
deflexed fruits. The species should be sought in southern Ohio.
