FAMILY: Potamogetonaceae (Zosteraceae, Najadaceae)
HABIT: Submersed aquatic with wing-flattened stem and
parallel-sided, grass-like leaves; flowering July-September; fruiting
SIMILAR SPECIES: Resembling P. robbinsii, but
differing in that stipules are not at all adnate to the leaves.
TOTAL RANGE: Que. to n. Alta. and s. B.C., s. to VA, WV, OH,
IN, ne. IL, IA, NE, nw. MN, and n. CA.
STATE RANGE: There are post-1950 specimens from shallow
waters of lakes and ponds in Champaign, Geauga, Logan, Ottawa, Portage, Stark,
Summit, and Williams counties.
STATE STATUS: 1980-1983: Threatened, 1984 to present:
HABITAT: Shallow to deep (7 m.) waters of lakes,
rivers, creeks, and wet swales.
HAZARDS: Unknown, but perhaps turbidity or mechanical
RECOVERY POTENTIAL: Presumed good, owing to the species'
wide range of habitats and its present scattered occurrences in the state.
INVENTORY GUIDELINES: Every effort should be made to obtain
fruiting specimens; however, in the absence of fertile material, sterile
specimens should be collected.
COMMENTS: This species should be sought in suitable
habitats, with special emphasis in western counties.
