HABIT: Erect perennial herb to 6 dm.; flowering June, July,
SIMILAR SPECIES: Sisyrinchium montanum is similar to
the common Sisyrinchium angustifolium, but can be distinguished by the
following characters: S. montanum - stems simple, spathes terminal, spathe-bracts unequal, pedicel
more or less ascending and rarely exceeding inner bract; S. angustifolium
- stems forking, spathes on peduncles from axils of leaf-like bracts,
spathe-bracts subequal, pedicels long, slender, outwardly arching or recurving
and much overtopping these spathes.
TOTAL RANGE: W. Nfld. to n. B.C., s. to Que., Ont., NY, NJ,
PA, n. OH, n. IN, n. IL, n. IA, NE, CO, NM; along mts. to VA and NC.
STATE RANGE: A post-1960 specimen exists only from Erie
County. 1955 records exist from Cuyahoga, Portage, and Summit counties. Braun
(1967) also lists a record from Clinton County.
STATE STATUS: 1980-1983: Threatened, 1984-1989: Endangered, 1990-1993:
Presumed Extirpated, 1994 to present: Endangered.
HABITAT: A variety of moist open situations: sandy or
gravelly shores, rock crevices, meadows, mixed woods; especially in disturbed
areas and clearings, old railroad beds, banks of ditches, and roadsides through
HAZARDS: Overshading by woody species as a result of
RECOVERY POTENTIAL: Presumed excellent due to its
generalized habitat and tolerance of disturbance.
INVENTORY GUIDELINES: Mature flowering or fruiting material
is needed for positive identification. Note the color of the spathes and the
connation of the outer bract-margins.
COMMENTS: This species may be more frequent than the records
indicate. It may have been overlooked due to its habit of occurring in
scattered local populations, its resemblance to the more common S. angustifolium,
and its occurrence in disturbed habitats. It should be sought throughout
authors divide this species into two varieties. Under this concept, Ohio plants
are the var. crebrum Fern. The typical variety is western in range. Var.
crebrum is erroneously treated as S. angustifolium by some
authors. Longstanding taxonomic and nomenclatural difficulties with this genus
are clarified by Ward (1968).
